You are adept at picking up magic training along the road.
Prerequisites: Spells known class feature; primary spellcasting ability score 15; Spellcraft 2 ranks
Benefit: If you beat the DC to identify a spell being cast by 10, you may add that spell to your “spells known” list for the next 8 hours. This spell must be on your spell list. You must have a clear view of the spellcaster and be able to hear any verbal components for this feat to function. Still spell and Silent spell foil the use of Spell Knack.
After 8 hours, your knack fades and you lose your inspiration for that spell. You may not use Spell Knack on that spell again for a number of days equal to the spell’s level.
A version of Quick Mnemonic for spontaneous casters. The reason it’s more limited–you can’t use Spell Knack on the same spell twice for a while–is to prevent cheaters from having two spellcasters in the party who just keep learning spells from each other.
I’ve also gone back and lowered the cost associated with Quick Mnemonic, because I think it was too harsh. Anyway, enjoy this feat and start using the enemy’s powers against them!
