Learned From Choker

Your hand bends and twists, seeking the throat of a creature you are grappling. You establish a choke hold, preventing that creature from speaking or casting spells with verbal components for the duration of the grapple. This spell is ineffective against creatures that do not have, or speak using, throats, as well as any creature that is immune to critical hits.

You can cast this spell with no penalty while grappling.
