Portentous Spell [one-action] Feat 16Manipulate Mental Oracle Spellshape Visual Source Player Core 2 pg. 143
Your spellcasting is rife with strange lights, mild fumes, and other captivating effects that befuddle your foes. If the next action you use is to
Cast a Spell, any creature that attempts to use a reaction triggered by your Cast a Spell activity takes a –2 circumstance penalty to attack rolls and skill checks rolled as part of the reaction. In addition, if the spell includes a spell attack or requires a saving throw, creatures you hit or that fail their saves are
fascinated with you until the start of your next turn.
Traits
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.
Mental: A mental effect can alter the target’s mind. It has no effect on an object or a mindless creature.
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. 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.
Visual: A visual effect can affect only creatures that can see it. This applies only to visible parts of the effect, as determined by the GM.
