Once upon a time I had come up with a character using the "fey'ri" as the bases for my mage. The unique thing about her was that she was a "balnorn" after much progression. She was a full 20 level warlock / 1 level mind bender / 3 level swashbuckler. My question is simple, is this a class that grants "a lich like template" minus the level adjustment or is it just a pure level adjustment? I'd gave her the lesser native outsider / undying type. I feel plus 2 is enough on the level adjustment. So whatever she misses on not claiming all of her power from birth she'd more than make up with turning into a balenorn. Truely savage, hence her chaotic neutral nature. I'm believing she'll need to take practiced spell caster to take advantage of her warlock levels also to satisfy the lich requirements. Question, what type of armor would best fit her? Also, would you give her a rapier or a whip? Or why not one of each? She's game. Please hit me up if you've for any ideas.
