An action with this trait requires a degree of mental concentration and discipline.

Light effects overcome non-magical darkness in the area, and can counteract magical darkness. You must usually target darkness magic with your light magic directly to counteract the darkness, but some light spells automatically attempt to counteract darkness.

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. 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.
