Just read this description on the wiki for the new alchemical crafting:
Arcane Augmentation IX
Effect: Spell Augmentation increases your effective caster level for sorcerer and wizard spells up to the listed level. This does not effect the Archmage spell-like abilities, nor does it effect spells you cast using items.
I guess it never occurred to me that it says "Arcane" augmentation.
Are divines getting the short end of the stick here and missing out or did I miss something? Where would infusions fit into this?
