Hemomancy
Certain spells included in this supplement have the special tag: hemomancy. Such a spell has an additional cost when it is cast: your own hit points. When you cast a spell with this tag, you must expend a number of hit points during the casting of the spell. The number of hit points you can spend is based on the spell’s level, and is shown in the table below. You may not use temporary hit points to cast hemomancy spells.Hemomancy Spell Table
