Create Bloodstone

You perform a quick ritual, imbuing a gem with your own vitality. As part of the casting, you expend one of your own hit die to be used by yourself or another creature you give the created bloodstone to. The stone and its hit die can be utilized once within the next eight hours, in one of two ways:

HEAL: As a bonus action, the creature holding the bloodstone can restore hit points to themselves or a creature they touch. The amount restored equaling to a roll of the hit die imbued into the stone (plus the casters Con modifier). Once used in this way, the die is expended.

HARM: As a bonus action, the creature holding the bloodstone can imbue their next weapon attack with additional damage. The damage is necrotic, equaling to a roll of the hit die imbued into the stone (plus the casters Con modifier). Once used in this way, the die is expended. The die and damage are not lost on missed attacks, but persist until an attack is successful.

At Higher Levels. When you cast this spell using a spell slot of 2nd or higher, you can expend one additional hit die into the gem for each slot level above 1st.
