It creeps
And leaps

Across the floor
Right through the door

A splotch, a blotch...”

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 significant amounts of acid damage, though you can reduce this significantly by filling as many armour slots as you can, especially the cloak.

Jellies also consume any items lying on the ground that the player has not seen, 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 weaken you for a time.

Tips & Tricks

  • When you hear 'a slurping noise', it means a jelly has just eaten something. Jellies will only eaten items that the player has not seen, so it is safe to drop items without fear of jellies eating them. Fortunately, they can't eat stones, large rocks, or artefacts.
  • If at all possible, you should fight jellies using ranged attacks to avoid their acid. 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 engaging it in melee.
  • Wearing a ring of resist corrosion or another source of rCorr will greatly reduce the chance of corrosion, as well as the damage you sustain.


Prior to 0.17, jellies would eat items on the ground that the player had seen.

Prior to 0.15, jellies were notorious for permanently weakening weapons and armour used in combat against them. The corrosion overhaul changed this.

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.
