Calling on dark arcane energy to surround and protect you, you sacrifice some of your vitality to manifest an oversoul made of a mixture of arcane energy and your own coagulated blood. You decide what appearance this oversoul will have.
When you cast this spell designate a number of your hit points (This amount can not exceed your hit point maximum) and you take that much necrotic damage (This necrotic damage can not be reduced, ignored, or avoided in any way). Your oversoul gains hitpoints equal to the amount of necrotic damage you took.
When you would take damage from any source while this spell is active, your oversoul instead takes the damage. If the damage your oversoul takes exceeds its remaining hit points, you take the remainder of the damage. This spell lasts until your oversoul is destroyed, you cast this spell again, or you finish a long rest.
* - (A cup or vialof the users blood (which the spell consumes))
