An action with this trait requires a degree of mental concentration and discipline.
Manipulate
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 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.
Wizard
This indicates abilities from the wizard class.

Your summoned creature appears in a detonation of arcane runes. If your next action is to Cast a Spell with the summon trait, all creatures in a 10-foot emanation around the creature you summoned take 1d4 fire damage per spell rank. If the creature summoned has the acid, cold, electricity, sonic, or spirit trait, you can deal damage of that type instead.
