Honor above all else.

Prerequisites: Crusader

Benefit: You can substitute Charisma for Wisdom for the purpose of all class abilities including spells and powers. For instance Cursader smite damage is calculated using the Charisma modifier and so are number of Paladin spells. On the other hand, perception checks are still wisdom based. You must always be honorous. This means:

You neither gain nor provide advantages by flanking.

You don't gain advantages by attacking prone enemies.

You cannot lie.
