| This spell steals the life of a living creature and grants it to the caster. Life will not be drained in excess of what the caster can capably absorb.
However, attempting to drain an undead or demonic creature will backfire on the caster.
Vampiric Draining is a level 3 Necromancy spell which deals negative energy damage to an adjacent monster and heals you for half the damage dealt (in 0.12 and earlier you can never heal the last HP). This spell does not effect certain monsters. Casting it on plants, constructs, or monsters with life protection will do nothing, while targeting demonic or undead monsters will seriously injure the caster (2d39/2 + 9 HP) (The game warns you about this beforehand).
The spell can only be cast in melee range, and strong monsters can often injure you for more than you are healed. It has a fairly high damage output and utility for a 3rd level spell, and it can be used by bloodless vampires and deep dwarves for healing.
- Although butterflies offer no XP benefits, they can be drained for health like any other living thing. Use 'Z' to cast the spell even though the game prompts you that there are no legal targets.
- Summoned monsters will take damage from the spell normally, but offer no healing.
− In versions 0.12 and earlier there was a bug that made the last HP unhealable by this spell.
