This page is about the spell. For species' innate recuperation, see regeneration rate.


Regeneration is a level 3 Charms/Necromancy spell which temporarily boosts caster's health regeneration.


While active your HP regeneration rate is increased by 100[1]. This effects lasts for 5 + 2d(<power> / 3 + 1)[2] turns. While Regeneration is active and your HP is below maximum, you also hunger significantly more quickly than usual.

For most characters, this means they will gain an additional 1 HP per turn, though this is affected by things such as the Slow Healing mutation (see regeneration rate for details). This effect can more than triple the speed at which you naturally heal, although it's more pronounced for low-level characters or characters with low maximum HP. This helps you recover between battles quickly, but don't expect it to make you invincible during combat; it only marginally increases your chance of survival in most dangerous encounters.

Additionally, characters under the effect of Regeneration will recover from sickness much faster. The increased recovery rate also helps counteract poison damage, making it much easier to simply wait out. As such, Regeneration can help you conserve potions of curing and lessens the need for poison resistance.

Be aware that Regeneration stacks with items that grant similar effects, such as an amulet of regeneration, troll leather armour, or being a troll or vine stalker. The effect does not stack with Trog's Hand, but followers of Trog can't cast spells anyway, so the issue is moot.

Characters who worship good gods will probably want to avoid using Regeneration, as the spell qualifies as Necromancy and will upset them. Also, mummies, deep dwarves and characters in lich form cannot use this spell. Vampires can, but the duration and benefit of the spell is dependent on their current satiation level.

The increase in metabolism can also cause issues, especially in branches with few edible corpses; an amulet of the gourmand is useful for characters making extensive use of Regeneration.

  • Prior to 0.6, the spell increased hunger rate even when at full HP.
