A chrysalis is a type of crystal gem that appears in dNetHack, notdNetHack and notnotdNetHack. It is a soft and has a base material of flesh.
Although named differently, all chrysalises are interchangeable and only count towards the total number of chrysalises held in open inventory at a time. The following items are considered 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 1⁄10 chance of a chrysalis being generated in the Undead Hunter quest home, in the 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:
- 1⁄900 with only 3 preservation upgrades.
- 1⁄600 with at least 6 preservation upgrades.
- 1⁄300 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 description) research upgrade.
- Divided by a factor of 3 if the hero currently has both the eye and defilement thoughts slotted and active.
- Halved if only the eye thought is slotted and active.
- Multiplied by 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 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 2⁄5 (40%), assuming maximum impurity scores (which cannot be achieved normally). However, for most roles, their sum impurity is likely to stagnate around 28–32, putting the odds closer to 2⁄13 (~15%), even with an 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. After the first, successive upgrades require 1 additional chrysalises per claimed upgrade. However, when choosing an 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 1⁄10 of melee attacks, or at will, make vomit attack with a range of 2 squares. On hit, afflict the target with 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 animals 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.
- 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 polymorphs 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 poisoned and disease-inflicting.
- Rot spores: Adds a retaliatory 1d1 disease-inflicting attack.
Eating 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 resistant. Taking any form of fire damage will end the effect prematurely, and otherwise has a 1⁄20 chance of timing out, counted each turn. If the hero is afflicted with caterpillars, spells they cast will only deal 1⁄2 damage, the range for pounding with polearms is reduced as if they had no skill in polearms, and they will also lose any multishot bonus they may have had.
Kindred of rot
The following monsters are considered kin of rot:
- swamp ferns
- swamp nymphs
- silvermen
- man-flies
- monsters with the swollen template
