So my rules question:
The archmage path ability Perfect Preparation says a prepared arcane caster no longer needs his spell book to prepare spells.
Does this mean he now prepairs spells like a cleric? Knowing every wis/sor spell (in the case of wizards) and is just limited by his number of prepared spells per level?
What was the intention behind this ability? It leaves alot of guessing.
Id like a dev's perspective on this please. As i know we are all rules lawyers to a point but i need something official ish,
