Orb of Destruction
| Conjures an orb made of pure destructive magic. Compared to most other projectiles, these orbs travel at a relatively slow pace. The orbs home onto their targets, yet because of their huge inertia, especially agile opponents may be able to outmanoeuvre them. The orbs need some time to stabilize, and a nascent orb will deal reduced damage.
Residents of the dungeon are able to maintain the orb until it impacts a target, but when cast by you the orb will dissipate upon leaving your line of sight.
|A conjured globe of pure magic that homes onto a designated target, albeit with massive inertia. A smart and agile person may move out of its path, causing it to miss its target. It cannot be avoided by Dodging skill, and is able to make sharp turns to hit adjacent targets.|
Orb of Destruction (often abbreviated OoD or IOoD, the I standing for "Iskenderun's") is a level 7 Conjurations spell which launches an orb of energy (speed 30, effectively indestructible) to attack your enemies. The orb itself is extremely powerful, dealing 9d21 damage at maximum power and range. This can potentially kill a Pandemonium lord with 3 or fewer casts. Creatures killed by this spell are typically blown apart into gory chunks (and, unlike a wand of disintegration, willpower has no effect), although any dragon capable of leaving a hide will not explode when it dies.
However, this spell is not without its flaws: the orb can stray off course and hit the wrong target or crash harmlessly into a wall, the spell does not reach its target instantaneously, and the orb deals much less damage when cast at close range to the target. As alluded to in the flavour text, the player spell is inferior to the monster version: your orb will dissipate when it leaves your line of sight, but an enemy's orb will continue to move around until it hits something. Unique among all spells in the game, this spell cannot be evaded by high EV but can be blocked by high SH.
While accuracy is tied only to spell power, its damage output also depends on the range:
- Range 1: 30% damage
- Range 2: 60%
- Range 3: 90%
- Range 4+: 100%
Sending a volley of orbs against a single dangerous monster is very effective. However, you should never send one out when the previous one is still adjacent to you as the orbs will collide, resulting in a large explosion and injuring you. This is especially likely to happen when hasted; make sure each orb has traveled at least one square away from you before launching the next one.

Tips & Tricks
- Due to the orb's predilection for swerving into walls, when in narrow hallways, launch at short range, since the orb will often fail at distances greater than 3-4 tiles (or use another spell better suited to the task). When launching an orb in wider hallways, situate yourself on the wall opposite from the one your target is nearest:
Example 1: Example 2: ########### ########### .@....M.... ......M.... ........... .@......... ########### ########### Bad: Risks hitting wall. Better: Much less risk.
- Orbs of Destruction are very effective against statues and other foes which have high resistance to elemental damage.
- When stair-dancing, orbs can be used as a fire-and-forget missile. Stand on the stairs, fire off an orb at the most dangerous target four or five squares away (for full power), then use the stairs. Since you still count as being on the current level while climbing the stairs, the orb doesn't dissipate immediately and has two turns of travel time -- enough to hopefully strike its target.
- This tactic is most effective while stair-dancing against a single powerful enemy; once the stairs have been surrounded by multiple foes, Orb of Destruction loses much of its effectiveness.
- Since orbs explode the corpses of enemies when they kill them, don't use an orb if you would like to harvest troll leather armour. Scale-bearing dragons do not explode and will still leave corpses, however.
- You can make an orb vs. orb situation work for you if you also have Blink or can retreat quickly: you can blink away safely while the enemy takes damage when the orbs collide.
- The spell is not too loud, except for when two orbs collide. Should this occur, be prepared for a swarm of curious enemies making a bee-line for you. This is an excellent technique for attracting half a dungeon level or dangerous uniques to one area of the dungeon, while you then start exploring from a different stairway.
- Be very careful when using this spell against monsters wearing shields (eg, Louise, Donald, Mennas). They will frequently block it, which can easily make the spell an expensive waste. Occasionally, monsters may even reflect the orb back at you!
- If you can see through a wall, the orb won't dissipate if you hide behind it. Ashenzari worshipers can have transparent walls whenever they want.
- Each casting of OoD creates a trail of short-lived purple clouds behind it. These are harmless, but can get in the way of any cloud spells you may wish to cast.
Defending Against IOODs
- Moving out of the way is the simplest way to avoid orbs of destruction, though the orbs' ability to home in on you makes this more difficult than it sounds. In particular, orbs can swerve to hit you any time you're adjacent to them, even if they're currently traveling past you. Walk perpendicular to the orb's path and start moving early, as you'll need some space to pull this off. In tight quarters without much empty space to maneuver in, ducking behind cover, such as around a corner or behind another monster, can also be effective.
- You can summon a Fulminant Prism right in front of an incoming orb. This will usually result in the orb and the prism destroying each other, making this an effective defense so long as you're not adjacent to the prism.
- Summoned creatures, undead thralls, or temporary allies can take the hit for you. Switch positions with your minion before the orb hits.
- Blinking at the last possible moment has a decent chance of putting you out of the orb's current trajectory, and if there's a wall behind you, the orb will be destroyed. Controlled blinking with a scroll of blinking is significantly safer, but teleporting usually takes too long (unless it's via a teleport trap).
- Firing your own orb at the caster will usually result in the orbs colliding and exploding violently. A bit expensive and dangerous in close quarters, but effective.
- Characters with high SH will occasionally block orbs, negating them entirely. This isn't something to rely upon, but it's nice when it happens.
- Being adjacent to the caster reduces the orb's damage tremendously.
- Note that you can never run faster than the orb. It has move delay of 3.33; even a hasted spriggan has a move delay of 4. Your only options are to block it or get out of the way.
- in 0.28, Orbs of Destruction were penalized more for short range. The power formula was also changed, making the spell a bit weaker.
- Prior to 0.20, Orb of Destruction could destroy dungeon features like doors, statues, or rock walls.
- Prior to 0.14, Orb of Destruction was available in the Book of Annihilations.
