A pulsating mass of acidic protoplasm. It can and will eat almost anything, and grows a little each time... “Beware of the Blob! It creeps And leaps and glides and slides Across the floor Right through the door And all around the wall, A splotch, a blotch...” -Burt Bacharach, “Beware of the Blob”

Useful Info

Jellies are obnoxious opponents which introduce the player to the concept of corrosion, a stackable debuff which inflicts a negative slaying bonus and an AC penalty. These attacks also deal heavy acid damage, though you can reduce this significantly by filling as many armour slots as you can, especially the cloak.

Jellies also consume any ammo fired at them, items they come across, or doors they pass through while wandering the Dungeon. Doing so heals them, and if they consume enough items they'll split, creating a second identical jelly. Although fairly weak, these opponents can destroy valuable items and permanently weaken your equipment.

Tips & Tricks

• When you hear 'a slurping noise', it means a jelly has just eaten something. If you're in the habit of leaving items monsters won't use lying around, consider picking them up for safe-keeping until the jelly situation is taken care of. Fortunately, they can't eat stones, large rocks, or artefacts.
• While jellies will not attack other living monsters, they will happily devour the corpses of the fallen along with whatever they were carrying. Try to kill the jelly before taking out anything else if you want corpses or loot.
• If at all possible, you should fight jellies using ranged attacks to avoid their acid. While they will simply consume ammunition fired into it, they cannot eat spell projectiles; magic is far and away the best means of dealing with them (including summons). Failing that, characters lacking magic can simply throw common stones or large rocks at the jelly, or use weak attack wands that would otherwise go to waste, at the very least softening the jelly up before you engage it in melee.
  • Bear in mind that sling bullets can be eaten. Sling users should quiver stones before attacking.
• Artefact weapons and armour are immune to corrosion, as are weapons or armour with a +5 or higher enchantment level (for weapons, only the damage enchantment counts).
• If you lack alternatives, you can simply wield a trash weapon you don't care about, march right up, and pound the thing. They lack any serious durability, but consider swapping out any useful ego armour you don't want to risk damaging.
• Wearing an amulet of resist corrosion or a source of preservation will greatly reduce the chance of corrosion. Crystal plate mail also resists corrosion most of the time. Bear in mind that these only reduce the chance, and are not guaranteed to save your gear.

History

Prior to 0.14, jellies would not split no matter how many items they consumed.

Prior to 0.13, jellies were more durable and hit harder, but only had speed 9.
