Converts some of the caster's blood into magical energy. The process is painful but never directly lethal. The efficiency of the conversion increases with the spell's power.

Sublimation of Blood is a level 2 Necromancy spell which converts your own HP into MP.

Useful Info

When cast, it returns 1 + X MP, where X is a negative binomial random variable with parameters r = 1 and p = 1 - 6 / power. The average amount of recovered MP per casting is power / 6. Each MP recovered costs you 1 to 4 HP with average 1 + 18 / power HP.[1]

The damage caused by this spell can never kill you, and never reduces more than 90% of your current HP at a time.

Sublimation of Blood can't be learned or cast by the undead, the nonliving (Gargoyle, Djinni, Statue Form), or when standing in Death's Door. Bloodless Vampires are unable to use this spell until turning alive again.

Tips & Tricks

  • Sublimation of Blood has good synergy with Makhleb's healing from kills. Be sure to use other sources of increasing your regeneration rate to regain the lost health quicker.
  • If you're in the heat of battle and intend to use this spell as an emergency MP source, don't let your MP reach 0; you need at least 2 MP to perform the first, hopefully successful, Sublimation spell.
  • If you have a source of increased HP regeneration, a moderate power Sublimination of Blood will allow you to rest for less turns. This can be very tedious.
