Really now? I've never played a Galotian before, tend to just go Kui-Tan to have fur and survive Uveto while keeping my gear as obscenely OP as possibly lol.
It's not that bad of a deal since you can still be (mostly) another race. Just the goo hair is constant. You snack on a bunch of terran treats or use skin clear to change your skin back to skin instead of goo.
LUCK from Dhaal combined with thermal/insulated underwear puts you at 45% resistance.
You could just go for one piece of undergarments and LUCK that gives you 35% and a massage from Pippa makes you cold free for an entire 24 hours. You only need 50% freezing resistance to become Uveto immune.
I usually don't bother with that, however. At high enough cold resistance you only take 1 per tile and I play merc which means every encounter I second wind 50% of my health back if I so desire. Might have to change if I make a new character for the psionics.
Now that I think on it. You can get to Uveeto before Zheng Shi I think so the best armor (for mercs) at that point is the Korgii chest piece from doing the Siege. And/or the frostwyrm armor. Both which takes you almost all the way to cold immunity by themselves.
