Nonlethal Spell
You can alter offensive spells to be less deadly. If your next action is to Cast a Spell that deals damage and doesn't have the death or void trait, that spell gains the nonlethal trait.
Traits
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
Spellshape actions tweak the properties of your spells. You must use a spellshape action directly before casting the spell you want to alter. If you use any action (including free actions and reactions) other than casting a spell directly after, you waste the benefits of the spellshape action. The benefit is also lost if your turn ends before you cast the spell. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
