A blue jelly, j, is a type of monster that appears in NetHack. Like most jellies, it is eyeless, amorphous, and sessile.
A blue jelly has a passive attack that triggers if attacked in melee, and deals cold damage dependent on the attacker's level that increases the jelly's HP by half the damage inflicted[1][2][3][4] - if enough HP is gained from this, the jelly will undergo division, halving its HP rounded up and creating a second jelly with almost the same amount of HP.[5][6][7] Blue jellies possess poison resistance and cold resistance.
Eating a blue jelly corpse of tins has a roughly 2⁄15 chance each of conferring cold resistance or poison resistance.
Generation
Randomly generated blue jellies are always created hostile.
Blue jellies appear among the j that make up the second quest monster class for Knights, and makes up 6⁄175 of the monsters that are randomly generated on the Knight quest.
Strategy
Avoid attacking a blue jelly in melee unless you have cold resistance, as blue jellies are much tougher than might be expected, and their cold passive attack can be deadly to inexperienced players. At their base level, they do (4+1)d6 damage, which gives a range of 5–30, and they can be generated at much higher levels.
While ranged attacks are preferable, but make sure you have enough options to finish the job—you won't be able to retrieve that lovely stack of daggers until the jelly is dead. The aklys is a solid option that likely should be used first - at worst, the aklys has a 1% chance that it will fail to return, but you will most likely do enough damage that you can kill the jelly with any remaining projectiles, preserving valuable darts, wand charges and/or other items.
Blue jellies are frequently employed for boulder forts, stashes, and the like since they are completely immobile.
History
The blue jelly first appears in NetHack 3.0.0.
Encyclopedia entry
I'd planned how to prevent the lock from sealing behind me; it required a temporary sacrifice, not cleverness. I used the door itself to help me cut off a portion of my body, after shunting all memory from the piece to be abandoned. The piece, looking inexpressibly dear and forlorn for a bit of blue jelly, would force open the outer door until I returned and rejoined it.
