Blood Mortem

You draw life and energy from willing participants around you, enhancing a creature you touch to their peak potential. 

Target up to 5 willing allies within 30ft of your position; each willing target takes 5d10 necrotic damage and has their maximum hit point reduced by the same amount. these hit points and hit point reduction cannot be regained except by a long rest. *(note: this damage bypasses resistances and immunities)*

For each creature who took damage, choose one ability to apply to your target. you cannot choose the same one more than once. 

- the targets weapon damage rolls gain 1d8 necrotic damage. 

-the target gains a 1d4 to ability checks and saving throws.

-the target gains 5d10 temporary hit points

-the target gains resistance to one damage type of your choice.

-the target gains a 1d4 bonus to attack rolls.

when the effects of the spell wears off, the target must make a constitution saving throw against your spell save DC; on a failed save, they suffer one level of exhaustion, as the large surge of power leaves their body, leaving them drained.
