Wiki doesn't have them up to date yet on new traits. Can we post them here.
I saw these +2 ones but not sure how they were made.
Skillchain bonus 2
Magic Attack bonus 2
Treasure Hunter 2
And any other +2 combos you found.
Orcish Counterstance - Counter
Vapor Spray - Max MP
Thunder Breath - Max HP
Wind Breath - Fast Cast
Barbed Crescent - Dual Wield
Amorphic Spikes - Treasure Hunter (Requires only this + the two Gilfinder spells)
Quadrastrike - Skillchain Bonus
These are the spells and the traits they affect. The Treasure Hunter effect is only TH1, don't believe I've seen any indication that Quadrastrike with the existing Skillchain Bonus combo deals even more damage from the skillchain effect, and there's no boost to Magic Attack Bonus.
