Osteomancy draws from sacrifice. Carve your own flesh to enhance these powers.
Ability Score Increase. Increase your Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.
Life Tax. When you cast an osteomancy spell of level 1+, you can sacrifice your life force to empower it, increasing the level this spell is cast at by one. You then roll a number of d6s equal to half the original spell’s level (rounded up, minimum of 1), taking Necrotic damage equal to the number rolled, which cannot be reduced in any way.
