Benefit You gain a +1 trait bonus on Knowledge (arcana) checks, and Knowledge (arcana) is a class skill for you. If you cast arcane spells, pick three spells on your spell list. You are particularly adept at casting these spells, so they function at +1 caster level when you cast them, and their save DCs (if any) gain a +1 bonus.
My question is what spell list should be used here? If it refers to the spells in the wizard's spellbook, it only affects a handful of 1st level & all of the 0-level spells - nice enough for a trait, but not nearly as interesting; if it's referring to the main list of available wizard's spells, it becomes waay cooler...
Your spell list is your class spell list (as modified by archetypes/traits/etc), it is not your current spells known.
If they are higher level spells it will take a while to come online. So the trait rewards patience.
That's what I thought, but wasn't quite sure.
Thanks!
