So I am thinking of building a Mystic Theurge designed for war, going Magus (bladebound) and Warpriest (ACG). And I am unsure if the Arcane Pool enchantment bonus & the Sacred Weapon enchantment bonus abilities stack correctly, given that they are both conferred abilities. According to the written rules they should as the Magus ability, Arcane Pool, is a time based (1 minute/activation) and the Warpriest, Sacred Weapon, is action based (1 round/activation).
Also in the 4th paragraph of the Sacred weapon entry it is stated that, "These bonuses stack with any existing bonuses the weapon may have, to a maximum of +5."
Any thoughts and opinions would be helpful. And an official ruling wouldn't hurt either. ;)
