I would like to craft an Alchemical Scepter or an Alchemical Shield for my Sorcerer. Was wondering if the TierIII fire effect Arcane Augmentation IX stacks with itself if i have two scepters. Would it be +4 bonus instead of +2? Or they don't stack togheter?
Tier 3:
Fire: Efficient Metamagic Maximize II, Greater Evocation Focus, Arcane Augmentation IX
