Aedon good with an already tanky build imo. Archer is the best So he can build AWA/AGI to find traps. With my cleric I can overheal to heal Aedon if anyone bothers him, Stun will also give you aggro for those that didn't know.
On Casual and Normal, double archer can be quite devastating for most areas. Most enemies will die before they get too close. Some boss fights can be a bit brutal as those enemies can close pretty fast (speed potions can be a lifesaver).
On Hard and Ironman, the double archer plan is hindered a bit by the increased defense and attack of enemies.
I think the stun effect from Archery Skill is under-appreciated on this form. Most players seem to go the route of Assassinate. Two archers can stun-lock tough enemies in a surprising amount of times.
