To cast this spell, you must expend five hit die, or else the spell fails.   You make a cut upon your hand and raise it above you, allowing the blood to seep down your arms and torso as you mutter dark words. Upon doing this, your non-magical damage rolls are increased by the hit dice expended once per turn, your AC increases by the number of hit dice expended, your hit points and maximum hit points increase by half of the hit dice rolled, and you can also cause yourself to dissipate and apparate to a seperate location you can see within 20 ft. of you as a bonus action. But, while these affects are active, your speed and any creature you have mounted's speed is decreased by 30 feet.
