While the spell lasts, you can use one of the following options, ending the spell immediately:

Liberation. When you fail a saving throw to avoid or end the Frightened, Grappled, or Restrained condition, you can take a Reaction to succeed on the save instead.

Respite. As a Magic action, you or an ally within the area regains Hit Points equal to 4d10 plus your spellcasting ability modifier.
