I put the DR and Energy Resist there to show what channeling that kind of power can do to the body, expecially since a failed word can kill a low-level caracter... I probably will tone those down though. The class was originally inspired by the Warlock, he had multiple types of words (Holy, Dark, Draconic, ect...) but it just didn't work-out.
I am in a bit of a conundrum about some of the abilities, I put in the DR, ER, and the Cleric BA/HD because the words have a good chance of failing, and he can only use a few per day reliably... its not exactly what I imagined at first but I am having trouble in scaling the Spell System in a balanced fashion.
