Aspect of Greed

You imbue a creature with dark power. Choose a willing creature within range. Whenever a creature within 60 feet of the target of the spell regains hit points, the creature can use their reaction to regain the hit points instead of the creature that normally would regain the hit points. This comes with a cost; if a creature casts a healing spell within 60 feet of you, you must use this reaction to regain hit points instead of them if you are able to. If the creature is under the effects of an Aspect of Wrath spell, the effect of the spell no longer requires your reaction.
