Quote:Cast a Spell while Grappled
You can attempt to cast a spell while grappling or even while pinned (see below), provided its casting time is no more than 1 standard action, it has no somatic component, and you have in hand any material components or focuses you might need. Any spell that requires precise and careful action is impossible to cast while grappling or being pinned. If the spell is one that you can cast while grappling, you must make a Concentration check (DC 20 + spell level) or lose the spell. You don’t have to make a successful grapple check to cast the spell.
[OoC: To cast a spell while grappled it either has to be a spell with no material component or you must have the Material component in your hand. Both spells you want to cast need a material component.
Regarding Hit Points: I know. If you look at the long line of numbers it says "0 damage."]
