A '''chrysalis''' is a type of [[crystal]] [[gem]] that appears in [[dNetHack]], [[notdNetHack]] and [[notnotdNetHack]]. It is a [[Engraving#Quality|soft]] and has a [[Object materials (dNetHack)|base material]] of [[flesh]].

There are seven types of chrysalises:
* '''novel Hedylidae chrysalis'''
* '''novel Hesperiidae chrysalis'''
* '''novel Lycaenidae chrysalis'''
* '''novel Nymphalidae chrysalis'''
* '''novel Papilionidae chrysalis'''
* '''novel Pieridae chrysalis'''
* '''novel Riodinidae chrysalis'''

==Generation==
Chrysalises do not randomly generate.
There is a {{frac|10}} chance of a chrysalis being generated in the [[Undead Hunter quest]] home, in the [[hidden door|hidden]] corridor left of [[Vicar Amalia]].
The chance of a chrysalis generating depends heavily on how many [[preservation]] upgrades they have claimed. At least 3 preservation upgrades must have been claimed for chrysalises to start generating:
* {{frac|900}} with only 3 preservation upgrades.
* {{frac|600}} with at least 6 preservation upgrades.
* {{frac|300}} with all 7 preservation upgrades.
Additionally, the sum of [[hero]]'s rot [[impurity]] and total impurity is subtracted from these base chances.
The resulting chances are then altered depending on a number of factors:
* Halved if the hero also possesses the "rot kin" (see {{sa|Description|description}}) research upgrade.
* Divided by a factor of 3 if the hero currently has both the eye and defilement [[thought]]s slotted and active.
** Halved if only the eye thought is slotted and active.
** Multiplied by {{frac|2|3}} if only the defilement thought is slotted and active.
* Halved if both the hero currently has both the weed and vacuous thoughts slotted and active.
** Multiplied by {{frac|3|4}} if either the weed or vacuous glyph are slotted and active, but not both.

The highest hypothetically achievable odds of a corpse leaving behind a chrysalis are {{frac|2|5}} (40%), assuming maximum impurity scores. However, for most roles, their sum impurity is likely to stagnate around 28–32, putting the odds closer to {{frac|2|13}} (~15%), even otherwise optimal setup.

==Description==
When [[applied]], a chrysalis allows a [[hero]] of any role to advance along the rot research path, granting them one upgrade. The less upgrades have been claimed, the higher the likelihood that a random upgrade will be chosen and applied, instead of the selected one. The following upgrades can be selected:
* Vomit rot: On {{frac|10}} of [[melee]] attacks, or at will, make vomit attack with a range of 2 squares. On hit, afflict the target with {{sa|Caterpillars|caterpillars}}.
* Rot wings: grants [[intrinsic]] [[flying]]
** Send forth a phantom duplicate: Only available after the rot wings upgrade has been claimed. Creates a [[butterfly swarm]] copy of yourself, equipped with your wielded weapons. Costs 45 power and 45 nutrition
* Become followed by the kindred of rot: Rot monsters will start to generate. All [[mindless]] monsters and [[animal]]s generate as [[swollen]], silvergrubs generate from rotting intelligent corpses and all eggs hatch as man-flies. All rot monsters are hostile to all other monsters, except for other rot kin.
** Become uninteresting to beings of rot: Only available after the rot kin upgrade has been claimed. Monsters that are {{sa|Kindred of rot|rot kin}} will be generated [[peaceful]]
* Feast on injury and destruction : Heal by 1.6% of max HP after every melee hit.
* Seek sapivorous immortality: Grants intrinsic [[life saving]] and adds a passive centipede-head disease [[bite]] attack to the hero's attack routine. When the life saving is triggered, the hero will temporarily [[polymorph]]s into a [[centipede]].
* Rot stinger: Adds a passive scorpion stinger attack, and a scorpion stinger disease attack to the hero's melee attack routine. Both attacks will be made [[poison]]ed and disease-inflicting.
* Rot spores: Adds a retaliatory 1d1 disease-inflicting attack.
After the first, successive upgrades require 1 additional chrysalises per claimed upgrade.

[[Eat]]ing a chrysalis grants 1 nutrition, but otherwise wastes the item.

===Caterpillars===
The caterpillars affliction deals damage to a monster based on maximum [[hp]]. Every time it triggers, they take 3.3% of their hp max as damage and a flat 26 points of damage, unless they resist [[disease]]. Disease resistant monsters only take 2% of their hp max as damage and a flat 8 points of damage. Additionally, they will lose 1 [[level]], unless they are [[drain resistance|drain resistant]]. Taking any form of [[Fire (element)|fire]] damage will end the effect prematurely, and otherwise has a {{frac|20}} chance of timing out, counted each turn. While under the affliction, [[spell]]s only deal {{frac|2}} damage, [[pounding]] with [[polearm]]s will be restricted as if the hero was wielding them at Restricted skill, and [[multishot]] will always be a maximum of 1.

==Kindred of rot==
The following monsters are considered kin of rot:
* [[swamp fern]]s
* [[swamp nymph]]s
* [[silvermen]]
* [[man-fly|man-flies]]
* monsters with the swollen [[Monster template|template]]
