Saintheart, if I can recommend an alternative for restatting Varanthian:

I rebuilt her as a remorhaz with unarmed swordsage levels and a heavy selection of Desert Wind maneuvers. Since she can use any part of her body for unarmed strikes, she uses superheated bodyslams, adding 8d6 fire damage to attack and getting multiple attacks according to her base attack bonus. Her bite-and-swallow technique actually becomes a secondary natural attack and much less of the main show (and she can reserve the bite-grab combo for an opportunity attack, offering herself a defense against chargers). Further, a remorhaz can burrow, so once she bites and grabs an enemy, she avoids further attack by the simple expedient of burrowing underground, swallowing the PC whole on the next round and burrowing under another PC, then pops up to repeat the trick on the following round. She's very dangerous as an ambush lurker. The swordsage maneuvers like Death Mark, Fire Snake, and Holocaust Cloak improve her ability to attack multiple foes at once.
