Spellcasting text and table don't match up.

Casting while in rage should be a level 1 ability.

The thing I don't get is just this... why is it a spellcasting class? It's got nearly nothing to do with spellcasting besides the ability to burn spell slots to increase the duration of your rage, and doesn't even get the ability to cast during it's rage until later on. It would work just fine as a pure melee or ToB prestige class.
