# Details Sangromancy spells allow casters to use their own blood and life force to push their magic beyond normal limits. The more these casters sacrifice, the more powerful their spells. While some train to reduce the strain of this magic on themselves, others use magical items or spellcasting foci to provide a more efficient path to Sangromancy mastery. # Hit Point Dice Sangromancy spells require casters to expend [[Hit Point Dice|Hit Dice]] as part of the casting. However if the caster does not have [[Hit Point Dice|Hit Dice]], it can use the [[Bloodletting]] rules to continue casting the spell.
