Welp, bar finding and grabbing some more Fiendish Powers, spending some additional cash and fixing all the 'Oh God why did I do that?' 5am mistakes, I think my character is done. I do plan to add to both the personality and appearance sections too.
Feel free to help me find my horrible, horrible mistakes. The maths involved in a 13th level Tristalt game with Templates and unique powers is ridonkulous, and I can't believe I haven't made a few.
