You create an aura of negative energy that weakens the life force of nearby creatures. Creatures within 15 feet of you can't regain hit points and have disadvantage on death saving throws, saving throws against exhaustion, and saving throws against effects that would reduce their hit point maximum.

On each of your turns before the spell ends, you can use your bonus action to temporarily disable the field until the start of your next turn.
