An action with this trait requires a degree of mental concentration and discipline.
Spellshape
Actions with the spellshape trait 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. Any additional effects added by a spellshape action are part of the spell's effect, not of the spellshape action itself.
You attune your great skill in performing to another, granting them a small measure of your skill as though anyone could do it. If your next action is casting a composition spell with an emanation area, its area spreads from a willing ally of your choice within 60 feet instead of you.
If you have Directed Audience, you can have that cone originate from the ally instead.
