Scintillating Spell Feat 16
Source Pathfinder Advanced Player's Guide
Your spells become a radiant display of light and color.
If your next action is to Cast a Spell that doesn't have the darkness trait, has no duration, and requires creatures to attempt a Reflex save, the spell explodes in a spray of scintillating lights, in addition to its other effects.
Each creature that failed its Reflex save against the spell is Dazzled for 1 round, and those who critically failed are instead Blinded for 1 round.
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.
LightLight 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.
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.
