'''The Royal Jelly''' ('''"TRJ"''' for short) is the [[list of jellies|jelly]] boss of [[the Slime Pits]]. Located in the center of Slime:5, it will not emerge until you've entered the stone structure it resides in (or you make enough [[noise]] nearby to awaken it), giving you plenty of time to clear the rest of the floor first.

'''The Royal Jelly''' (or '''TRJ''') is the [[list of jellies|jelly]] boss of [[the Slime Pits]], located on Slime:5. It has an impressive amount of [[HP]], powerful [[acid]]ic melee attacks, exceptional speed, and an unusual defense mechanism: whenever it's damaged, it spawns various powerful jelly-type monsters to attack you ([[azure jellies]], [[quicksilver ooze]]s, [[rockslime]]s, and [[acid blob]]s). These monsters don't count as [[summon]]s, but aren't worth XP. Unlike most other monsters, TRJ can choose to actively retreat behind its other jellies.

==Strategy==
 +
The Royal Jelly is a formidable foe. Trying to run at it with an [[axe]] will likely lead to your death, even with rCorr, as you'll be quickly surrounded by 8 high-level jellies.
 +
 
 +
Many strategies exist to take on TRJ. No matter what you're doing, it is recommended to have corrosion resistance, clear the rest of the floor, and use all sorts of buffs ([[haste]], [[might]], [[brilliance]]...). These not only increase your chance of winning, but also help you if something goes terribly wrong.
 +
 
 +
*'''Corridor fighting'''. Fighting a group of monsters in a corridor is usually a good idea, and TRJ isn't any different. The corridors available might not be perfect, but they can allow you to fight 2-3 slimes at a time instead of 8 - already a huge improvement.
 +
:By using [[summon]]s ([[scroll of summoning]], [[phantom mirror]], [[Summoning|spells]]...) in the corridor, you can prevent TRJ's reinforcements from attacking you, turning it into a fight in your favour. Summons can also prevent TRJ from retreating. Melee, ranged weapons, and single-target spells (like [[Iron Shot]]) all work well in this position. See the [[#Gallery|Gallery]] section for a demonstration.
 +
 
 +
*'''[[Torment]] + [[Scroll of immolation|Immolation]]'''. Slimes are natural monsters, so they are vulnerable to torment's half-HP effect. TRJ spits out other jellies, which are perfect targets for immolation's explosion effect. See TRJ at the edge of sight, torment once, use immolation, then find a way to ignite it (usually a strong ranged attack, preferably piercing). Some characters will want/need to use torment a second time.
 +
:The big risk of this strategy is that torment also reduces your HP by half (unless immune). A [[potion of lignification]] gives torment immunity, though it also melds armour and makes you stationary. If you are confident in your damage, doing this "raw" or with some rN+ can work out fine. Also, note that [[rockslime]]s are resistant to fire and won't take much damage from immolation explosions.
 +
:*'''Snakebombing'''. [[Summon]]s and [[zombie]]s are also affected by immolation. Use the strategy listed above, but after tormenting, create lots of summons (or Wretches, for [[Kiku]] followers). Then, once they are close enough, immolate them. Inner flame jellies and inner flame allies will fight, and one will die, causing the other to be hit by an explosion. A lot of summons (e.g. multiple [[scroll of summoning]], [[Haunt]]...) may be needed. A [[scroll of butterflies]] can work in theory, but is unpredictable. Note that [[Death Channel]]'s spectres cannot be immolated, due to their infinite willpower.
 +
 
 +
*'''Blasting it from range'''. A powerful piercing/AOE/smite-targeted ranged attack can be strong enough to kill TRJ from full [[LOS]] range, whether on its own or when combined with immolation. [[Fire Storm]] and [[Chain Lightning]] will work as you'd expect, but other spells can be used too.
 +
**[[Ignition]] turns the fight into a cakewalk; since jellies always spawn near TRJ, the boss is hit by 9 Ignition explosions at a time. Immolation isn't required here.
 +
**[[Maxwell's Capacitive Coupling]] doesn't have AOE, but instantly kills any monster, TRJ included. Stand on an upstairs, use MCC when TRJ is as far as possible, then retreat upwards to escape the aftermath. Then enter Slime:5 from another staircase, luring the residue one by one.
 +
**[[Discord]]. Turns spawned jellies hostile to each other. Immolate and you win.
 +
**[[Eringya's Noxious Bog]]. Immolation creates a flame cloud every time damage is dealt, including poison damage. So you can haste up, create a bog, and kite TRJ. Once enough jellies have spawned, use immolation, which will eventually trigger an explosion. Ideally, you'll have [[Ignite Poison]] to cause the immolation chain reaction (though Ignite Poison isn't needed).
 +
**For melee characters, throwing [[javelin]]s at high skill (+ immolation) can be used to the same effect. TRJ is vulnerable to [[silver]], so silver javelins are especially effective. Throw until you create a couple slimes, use immolation, then throw to activate the fireworks.
 +
**Lower level spells, such as high-power [[Plasma Beam]], can be used, too.
 +
 
 +
*'''[[Scroll of vulnerability]]'''. At 180 willpower, it's normally hard to use Hexes. Using vulnerability cuts that in half, making it reasonable for repeated hexes to get through. Be ''very'' careful; since vulnerability also cuts your will in half, [[golden eye]]s and [[great orbs of eyes]] can inflict nasty statuses.
 +
**Standard high-tier stab hexes ([[paralysis]], [[Petrify]]) work. These are best used in a corridor, since slimes still spawn when TRJ is disabled.
 +
**[[Polymorph]] turns TRJ into something else. You usually get a [[shard shrike]], [[titan]], [[dragon]] or, if especially lucky, a [[death yak]]. This creates a mass of jellies still, but once you deal with them, no more will spawn from the polymorphed TRJ.
 +
**[[Lugonu]]'s Banish sends TRJ to [[the Abyss]]. Banish doesn't count as a kill, meaning the stone walls won't open. Lugonu worshippers have a way to open stone walls (Corruption), however.
 +
 
 +
*'''Opening the chambers yourself'''. The chambers are blocked by stone walls. There are a few ways to break them ([[Shatter]], [[Fedhas]]' Overgrowth, Lugonu's Corruption). Shatter is extremely loud and will attract just about everything, though you can lure monsters away and take the loot for yourself. Note that Shatter is poor as a combat spell, since jellies are resistant to it.
 +
 
 +
*'''Misc. methods of killing:'''
 +
**Dedicated [[stab]]bers ''can'' attempt to stab TRJ while its sleeping. It often isn't advisable, since you can always fail to one-shot, meaning you'll have to face TRJ and a huge mass of slimes. Even if you do kill, you'll still have to deal with the leftovers.
 +
**Many god abilities can kill TRJ (see "Blasting it from range"). [[Qazlal]]'s Disaster Area + immolation, [[Beogh]]'s smites, or a surge of cards from [[Nemelex]] may be enough to kill.
 +
 
 +
*'''[[Jiyva]]'''. Of course, if you wish to avoid this entire mess, you can simply worship Jiyva and waltz in at 6* of piety. Most of the treasure will inevitably get eaten, but you'll at least be able to make off with the rune and whatever [[artefact]]s were present. As per usual with Jiyva, [[Apportation]] may come in handy.
 +
 
 +
===Escaping===
 +
*Take great care around [[quicksilver ooze]]s. They can [[engulf]] you, rendering unable to use [[spell]]s, [[scroll]]s, or [[god]] abilities until you move a tile or kill the ooze. Being surrounded by 8 jellies is already deadly, being unable to [[blink]] or [[teleport]] out makes it even worse.
 +
**[[Amphibious]] and [[unbreathing]] characters are immune to engulf.
 +
*Haste can let you run away from most jellies if you are not already in melee range. Only [[quicksilver ooze]]s are outright faster than a hasted Human, though TRJ is only slightly slower than that. Both haste and [[Swiftness]] can be used to outrun these two. If you can get to the stairs without any adjacent jellies, you're safe.
 +
*TRJ will not follow you upstairs, but its generated slimes will. If you plan on running back upstairs mid-fight, expect some of its spawns to follow you.
 +
:If you've accidentally created an army of jellies and need to abort, heal up and stair dance so you can clear out the reinforcements without dealing with too many of them at a time. Entering the floor from different staircases will let you avoid being immediately surrounded.
  
==Tips & Tricks==

===Tips & Tricks===
===How To Kill It===
+
*TRJ retreats behind its spawned jellies periodically. Use piercing, AOE, or smite-targeted attacks that can hit TRJ past its reinforcements. Otherwise, you'll need to fight through or reset the fight.
*Melee fighters should ''not'' simply charge in and bash the thing. Even with corrosion resistance and heavy armour, having eight corrosive opponents attacking you repeatedly will quickly send your offensive capabilities and your AC plummeting, leaving you weak and very vulnerable. Always soften it up before engaging it in melee, and buff heavily: Potions of haste, might, and/or brilliance can help you deal lethal damage to TRJ before its reinforcements make life unbearable. [[Berserk]]ing also works, but it greatly limits your other options and might run out and leave you helpless while surrounded by angry jellies.
+
*Watch out when using [[distortion]]. Banish doesn't count as a kill, so if you banish TRJ without a way to break through stone walls, you'll need to go to the Abyss and kill it.
*[[Stealth]]y [[stab]]bers may be tempted to try to kill it in a single blow, followed by a timely teleport to safety. This is entirely possible, but TRJ has enough HP to survive all but the most highly-skilled assassination attempts. Furthermore, several enemies guard the corridors leading to its chamber; should any of them wake up, the noise you make while fighting them might be enough to also wake TRJ. Try it at your own risk: equip a [[dagger]] for maximum stabbing damage, and be prepared to change strategies should it suddenly wake up.
 
*Fighting TRJ in one of the central corridors restricts how many monsters can reach you. Just be prepared for the angry jelly mob once you're done.
 
*TRJ retreats behind its spawned jellies periodically, forcing you to fight through them. Attack wands, [[bolt spells]], weapons of [[penetration]], and [[smite]]-targeted attacks will all help to pierce through the surrounding jellies. Or, summon your own allies while adjacent to TRJ and box it in before attacking (works best in the corridors).
 
*Ranged weapon fighters can just pelt the Royal Jelly with projectiles. Kiting it will still be difficult, as it's almost as fast as a [[centaur]] and you'll likely have to deal with the ranged attacks of the acid blobs it spawns.
 
*[[Banish]]ing TRJ via [[Lugonu]]'s [[ability]] doesn't unlock the vault, meaning you'll need some way to bypass [[stone wall]]s. Corrupting the floor will open the vaults easily, though [[Shatter]] can also do so without unleashing an abyssal horde. Failing all else, a trip to the [[Abyss]] to kill TRJ will be necessary.
 
*TRJ is a natural creature, and thus vulnerable to [[torment]]. Reading two or three [[scrolls of torment]] will drop it to near death, and a few [[bolt spells]] or [[smite]]-targeted attacks will kill it despite the surrounding army. Just be aware that this strategy will also leave your own HP dangerously low (rN+++, [[Statue Form]], or being [[undead]] are highly recommended).
 
*If you decide to use summoning magic, you can't do better than [[Dragon's Call]]. Interspersing this with other high-level summons can create a wall of units capable of matching TRJ's allies. You'll need to plan ahead, of course: 18 or 19 Summonings skill, high intelligence, a ring of [[wizardry]], and [[Recall]] are the bare minimum, with a method of [[channeling]] or spare [[potions of magic]] being highly recommended.
 
*Worshipers of [[Trog]] can also benefit from summons; a small pack of berserk [[iron troll]]s or [[stone giant]]s should survive long enough to deal tremendous damage to TRJ before being dissolved.
 
*Attack TRJ 1-2 times so it spawns jellies/oozes, read a [[scroll of immolation]], then kill any of the spawns to set off a chain reaction. This strategy risks self-immolation, so ensure that you can kill one of the spawns at a distance immediately after reading the scroll ([[orb of destruction]] or a cloud spell work well). Being [[haste]]d helps, giving TRJ less time to respond to your appearance and move out of explosion range. Having rF+++ or a [[potion of resistance]] is useful as a failsafe in case you get caught in the blast.
 
*Spawned jellies are unaffected by several combat [[Necromancy]] spells like [[Borgnjor's Vile Clutch]], [[Infestation]], or [[Death Channel]], and nothing in the Slime Pits can be [[Animate Dead|zombified]] or turned into [[Simulacrum|simulacra]]. Characters relying on Necromancy should consider avoiding TRJ until other means of fighting it are acquired (though [[Agony]] will chew through its HP if you can manage to get past its magic resistance). [[Infestation]] on the jellies TRJ spawns works like a charm, turning his strength against him.
 
*TRJ can be [[wand of polymorph|polymorphed]] if your [[Evocations]] is fairly high and you reduce its MR with a [[scroll of vulnerability]] or two, but this is generally inadvisable. Succeeding will immediately create a very large number of jellies, and due to TRJ's high [[HD]], whatever it turns into will also be dangerous; expect [[titan]]s, high-end [[dragon]]s, or [[list of birds|shrikes]]. If you ''do'' manage to polymorph TRJ, it will no longer spit out extra jellies every time it's hit and killing it will still unlock the rune vaults; after dealing with the army of jellies, taking a polymorphed TRJ down will be fairly simple by comparison.

Useful Info

The Royal Jelly (or TRJ) is the jelly boss of the Slime Pits, located on Slime:5. It has an impressive amount of HP, powerful acidic melee attacks, exceptional speed, and an unusual defense mechanism: whenever it's damaged, it spawns various powerful jelly-type monsters to attack you (azure jellies, quicksilver oozes, rockslimes, and acid blobs). These monsters don't count as summons, but aren't worth XP. Unlike most other monsters, TRJ can choose to actively retreat behind its other jellies.

Killing the Royal Jelly causes two things to happen:

  • The translucent walls of the four central vaults that the Royal Jelly guarded will come crumbling down, allowing you access to the slimy rune of Zot and the piles of treasure.
  • Jiyva, the god of slimes, immediately ceases to exist once its biggest sentient worshiper dies. You can prevent this by worshiping Jiyva yourself before killing TRJ, but killing such a high-ranking jelly will result in penance. Note that you can't escape divine wrath by killing TRJ.

TRJ can't pursue you through stairs, allowing you to abort attempts at killing it that you don't feel confident you can complete.

Strategy

The Royal Jelly is a formidable foe. Trying to run at it with an axe will likely lead to your death, even with rCorr, as you'll be quickly surrounded by 8 high-level jellies.

Many strategies exist to take on TRJ. No matter what you're doing, it is recommended to have corrosion resistance, clear the rest of the floor, and use all sorts of buffs (haste, might, brilliance...). These not only increase your chance of winning, but also help you if something goes terribly wrong.

  • Corridor fighting. Fighting a group of monsters in a corridor is usually a good idea, and TRJ isn't any different. The corridors available might not be perfect, but they can allow you to fight 2-3 slimes at a time instead of 8 - already a huge improvement.
By using summons (scroll of summoning, phantom mirror, spells...) in the corridor, you can prevent TRJ's reinforcements from attacking you, turning it into a fight in your favour. Summons can also prevent TRJ from retreating. Melee, ranged weapons, and single-target spells (like Iron Shot) all work well in this position. See the Gallery section for a demonstration.
  • Torment + Immolation. Slimes are natural monsters, so they are vulnerable to torment's half-HP effect. TRJ spits out other jellies, which are perfect targets for immolation's explosion effect. See TRJ at the edge of sight, torment once, use immolation, then find a way to ignite it (usually a strong ranged attack, preferably piercing). Some characters will want/need to use torment a second time.
The big risk of this strategy is that torment also reduces your HP by half (unless immune). A potion of lignification gives torment immunity, though it also melds armour and makes you stationary. If you are confident in your damage, doing this "raw" or with some rN+ can work out fine. Also, note that rockslimes are resistant to fire and won't take much damage from immolation explosions.
  • Snakebombing. Summons and zombies are also affected by immolation. Use the strategy listed above, but after tormenting, create lots of summons (or Wretches, for Kiku followers). Then, once they are close enough, immolate them. Inner flame jellies and inner flame allies will fight, and one will die, causing the other to be hit by an explosion. A lot of summons (e.g. multiple scroll of summoning, Haunt...) may be needed. A scroll of butterflies can work in theory, but is unpredictable. Note that Death Channel's spectres cannot be immolated, due to their infinite willpower.
  • Blasting it from range. A powerful piercing/AOE/smite-targeted ranged attack can be strong enough to kill TRJ from full LOS range, whether on its own or when combined with immolation. Fire Storm and Chain Lightning will work as you'd expect, but other spells can be used too.
    • Ignition turns the fight into a cakewalk; since jellies always spawn near TRJ, the boss is hit by 9 Ignition explosions at a time. Immolation isn't required here.
    • Maxwell's Capacitive Coupling doesn't have AOE, but instantly kills any monster, TRJ included. Stand on an upstairs, use MCC when TRJ is as far as possible, then retreat upwards to escape the aftermath. Then enter Slime:5 from another staircase, luring the residue one by one.

Once enough jellies have spawned, use immolation, which will eventually trigger an explosion. Ideally, you'll have Ignite Poison to cause the immolation chain reaction (though Ignite Poison isn't needed).
    • For melee characters, throwing javelins at high skill (+ immolation) can be used to the same effect. TRJ is vulnerable to silver, so silver javelins are especially effective. Throw until you create a couple slimes, use immolation, then throw to activate the fireworks.
    • Lower level spells, such as high-power Plasma Beam, can be used, too.
  • Scroll of vulnerability. At 180 willpower, it's normally hard to use Hexes. Using vulnerability cuts that in half, making it reasonable for repeated hexes to get through. Be very careful; since vulnerability also cuts your will in half, golden eyes and great orbs of eyes can inflict nasty statuses.
    • Standard high-tier stab hexes (paralysis, Petrify) work. These are best used in a corridor, since slimes still spawn when TRJ is disabled.
    • Polymorph turns TRJ into something else. You usually get a shard shrike, titan, dragon or, if especially lucky, a death yak. This creates a mass of jellies still, but once you deal with them, no more will spawn from the polymorphed TRJ.
    • Lugonu's Banish sends TRJ to the Abyss. Banish doesn't count as a kill, meaning the stone walls won't open. Lugonu worshippers have a way to open stone walls (Corruption), however.
  • Opening the chambers yourself. The chambers are blocked by stone walls. There are a few ways to break them (Shatter, Fedhas' Overgrowth, Lugonu's Corruption). Shatter is extremely loud and will attract just about everything, though you can lure monsters away and take the loot for yourself. Note that Shatter is poor as a combat spell, since jellies are resistant to it.
  • Misc. methods of killing:
    • Dedicated stabbers can attempt to stab TRJ while its sleeping. It often isn't advisable, since you can always fail to one-shot, meaning you'll have to face TRJ and a huge mass of slimes. Even if you do kill, you'll still have to deal with the leftovers.
    • Many god abilities can kill TRJ (see "Blasting it from range"). Qazlal's Disaster Area + immolation, Beogh's smites, or a surge of cards from Nemelex may be enough to kill.
  • Jiyva. Of course, if you wish to avoid this entire mess, you can simply worship Jiyva and waltz in at 6* of piety. Most of the treasure will inevitably get eaten, but you'll at least be able to make off with the rune and whatever artefacts were present. As per usual with Jiyva, Apportation may come in handy.

Escaping

  • Take great care around quicksilver oozes. They can engulf you, rendering unable to use spells, scrolls, or god abilities until you move a tile or kill the ooze. Being surrounded by 8 jellies is already deadly, being unable to blink or teleport out makes it even worse.
  • Haste can let you run away from most jellies if you are not already in melee range. Only quicksilver oozes are outright faster than a hasted Human, though TRJ is only slightly slower than that. Both haste and Swiftness can be used to outrun these two. If you can get to the stairs without any adjacent jellies, you're safe.
  • TRJ will not follow you upstairs, but its generated slimes will. If you plan on running back upstairs mid-fight, expect some of its spawns to follow you.
If you've accidentally created an army of jellies and need to abort, heal up and stair dance so you can clear out the reinforcements without dealing with too many of them at a time. Entering the floor from different staircases will let you avoid being immediately surrounded.

Tips & Tricks

  • TRJ retreats behind its spawned jellies periodically. Use piercing, AOE, or smite-targeted attacks that can hit TRJ past its reinforcements. Otherwise, you'll need to fight through or reset the fight.
  • Watch out when using distortion. Banish doesn't count as a kill, so if you banish TRJ without a way to break through stone walls, you'll need to go to the Abyss and kill it.

History

  • In 0.31, TRJ became immune to throwing nets. Also, many new Slime:5 layouts were added. As some don't have convenient corridors, certain strategies are harder to use. Previously, there was only one vault.
  • Prior to 0.27, death oozes were created, instead of quicksilver oozes and rockslimes.
  • Prior to 0.23, exploding the Royal Jelly with Uskayaw's Grand Finale didn't generate any jellies.
  • Prior to 0.19, the Royal Jelly could eat items and could heal itself when shot with anything other than stones.
  • Prior to 0.16, the Royal Jelly did not immediately spit out a large number of jellies when polymorphed, making it a viable combat strategy.
  • Prior to 0.15, hitting the Royal Jelly could generate brown oozes as well.
  • Prior to 0.11, the Royal Jelly was not able to regenerate naturally. This made the fight much easier to complete over several small assaults.
