Elaborate Flourish Feat 4
Source Pathfinder Advanced Player's Guide
You embellish your spellcasting with entrancing flourishes and grand pronouncements, making it harder to identify or counter.
If the next action you use is to Cast a Spell, creatures with the ability to Cast that Spell don't automatically know what the spell is.
In addition, creatures that witness your spellcasting take a -2 circumstance penalty to checks to identify the spell with Recall Knowledge and checks to counteract the spell during its casting (such as with Counterspell).
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ConcentrateAn action with this trait requires a degree of mental concentration and discipline.
ManipulateYou 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.
MetamagicActions 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.
SorcererThis indicates abilities from the sorcerer class.
