Hemoturgy

You display your understanding of Hemoturgy, the magic of lifeblood. You create one of the following magical effects within range:

• You cause harmless blood to trickle from your eyes, nose, ears, pores, or mouth for 1 minute.
• You cause the air to fill with the metallic taste of blood, and the scent of a butcher shop floor for 1 minute. 
• You cause blood to return to the spot from whence it was spilt, causing blood to recede back into cuts or bodies over the course of 1 minute.
• You create a small incision through which blood is magically drawn, allowing you to take a sample of blood from yourself, a willing creature, or a dead creature.
• You instantaneously slow your pulse down to nothing, though you stay alive.
• You alter the appearance of your eyes for 1 minute to appear bloodshot, ruptured, or as pools of blood, or another similar effect

If you cast this spell multiple times, you can have up to three of its 1-minute effects active at a time, and you can dismiss such an effect as an action.
