List 1: That's the Seven Thousand Cuts Kobold. And I think getting your Marilith out of any DM is a bit hard.
Remember, you get gestalt goodies for staying in your base class. Grab two with reasonable synergy, one of which is flexible (caster, meldshaper, psion etc), and you'll produce a stronger character than most PrCs just from HD, BAB, saves and armor proficiencies.
Ah no fair Callix, I didn't know you were in the thread!
And actually, if I used her in any game I wouldn't take leadership or do the mind swap, I'd just use the base kobold... Which makes at most 250 attacks a round.
My problem, though, is that I'd still rather dip around for special abilities or one time synergies or grab capstone PrC abilities than ride two base classes pasts level 6 or so.
