Lore of Acavna and Amaznen (Ex): At 2nd level, a child of Acavna and Amaznen is further initiated into the arcane secrets passed down from Azlant. This gives her minor spellcasting abilities and access to lore collected to give her an edge against the enemies of humanity.
The child of Acavna and Amaznen gains a spellbook containing 4 0-level wizard spells of her choice. She can prepare and cast these spells as a wizard, using her fighter level as her caster level. She can prepare a number of 0-level spells each day equal to 1 + 1 per 6 fighter levels.
She also gains a +2 bonus on Knowledge checks relating to Azlant and the Azlanti, and on Knowledge checks to identify and learn the powers and weaknesses of aboleths, demons, serpentfolk, and undead.
This ability replaces the bonus feat gained at 2nd level.
