Blood Sacrifice

You offer a sacrifice of your own blood from a self-inflicted wound that infuses with a weapon you are holding or a spell that you cast. While the blood sacrifice is active, your weapon or spell (if the spell has any visual effects) takes on a crimson hue.

When casting this spell, you take 1d4 points of damage. Until the start of your next turn, upon a hit, all attacks that you make against a target inflict an additional 1d8 points of damage.

This damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8). The damage you take also increases as your powers grow stronger. When you reach 5th level, your damage die increases to a 1d6, at 11th level (1d8), and at 17th level (1d10).
