Martial Arcanist

Type of Feat: Class
Prerequisite: Abjurant Champion 5

At 5th level, you master the art of combining your militant and mystical training. From this point on, your caster level in a chosen arcane spellcasting class is equal to your base attack bonus (unless it would otherwise be higher). For example, a 7th-level fighter/1st-level wizard/5th-level abjurant champion has a base attack bonus of +12 (and thus a caster level of 12th). You can apply this benefit to only one arcane class to which you have added spellcasting levels by your advancement as an abjurant champion.
