Suppress Regeneration

You temporarily remove the ability to regenerate from a creature you can see within range. The target must make a Constitution saving throw. On a failed save, the target can't regain hit points from the Regeneration trait or similar spell or trait for the duration. The target can receive magical healing or regain hit points from other traits, spells, or actions, as normal. At the end of each of its turns, the target can make another Constitution saving throw. On a success, the spell ends on the target.
