Portentous Spell [one-action] Feat 16Legacy Content
Manipulate Mental Metamagic Oracle Visual Source Advanced Player's Guide pg. 81 2.0
Your spellcasting is rife with strange lights, esoteric gestures, 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 roll 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.
Metamagic: Actions with the metamagic trait, usually from metamagic feats, tweak the properties of your spells. You must use a metamagic action directly before Casting the Spell you want to alter. If you use any action (including free actions and reactions) other than Cast a Spell directly after, you waste the benefits of the metamagic action. Any additional effects added by a metamagic action are part of the spell’s effect, not of the metamagic 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.
