Yes, yes, I'm quite aware of all that. You'll notice that in post #17 I asked Lord Raven about just that issue, because it seems to me that many inhereted templates could be granted to a character rather than being part of them from the start. Half-Celestial especially seems to be something that the divine spirits could bestow upon an individual if they were worthy. I'm treating Mineral Warrior in this case not just as a stoney-skinned dude, but as someone who's skin was made hard as adimantum as part of the reward process I'm talking about.
Now if LR doesn't see fit to grant my request, I'll obviously have to rework some of the crunchy bits of the character. I may even have to drop the Half-Celestial part, which would be sad since I only decided on it for flavor reasons rather than the stuff it offered (it really isn't worth a +4 LA IMO). Anyway, until LR says otherwise, I'm going with what I have. Thanks for looking it over though Question!
