Arcane Enlightenment (Su)
Source: Advanced Class Guide, p. 43
The shaman’s native intelligence grants her the ability to tap into arcane lore. The shaman can add a number of spells from the sorcerer/wizard spell list equal to her Charisma modifier (minimum 1) to the list of shaman spells she can prepare. To cast these spells, she must have an Intelligence score equal to at least 10 + the spell’s level, but the saving throw DCs of these spells are based on her Wisdom rather than Intelligence. When she casts these spells, they are treated as divine rather than arcane. Each time the shaman gains a level after taking this hex, she can choose to replace one of these spells with a new spell from the sorcerer/wizard spell list.
