Life Tap

The most dedicated of practitioners of the dark arts are willing to sacrifice everything in their pursuit of greater power, and this spell is one example of how far some warlocks are willing to go. When casting this spell, the caster cuts a gash in her own body, using her blood as a reagent. She ritually regains 1 level of spell slots for every 8 hit points she sacrifices in this manner. Each round, starting on the round she casts the spell, she deals damage to herself equal to her caster level or less. She must make a Concentration check to continue casting the spell, as is normal when the spellcaster takes damage while casting. (If the caster fails this Concentration check, the spell ends and she gains spell slots according to the damage she has already dealt.) Once she has drained all the blood she wishes, completing the spell only takes a few moments of incantations and the spell slots are restored. Material Component: The warlock's blood. Focus: A ritual weapon.
