Shackled Spellcasting

You have learned to work spells within the boundaries unique to bondage. If your speech is inhibited, such as by a gag or mouth covering, you can ignore the Verbal components for spells. This does not overcome the effects of the Silence spell.

In addition, if you are Restrained or bound, you can ignore Somatic components for spells, and spell attack rolls are not made at Disadvantage for being Restrained.
