Dwarf, Badlands

Spell resistance that can't be lowered is a drawback. You know that, right?

Honestly, just because of that, I wouldn't want to play one of these guys, though the 1 LA for modifiers that, while decent, aren't nearly as good as you could get even with a decent template is also off-putting.

Anyway, this is just odd. Ability damage and drain at level 1 are nuts and shouldn't exist, so the possibility that the PCs could be hit by such things at level 1 is nutty. The inability to be buffed and damaging allies for trying alone makes this race unplayable, or at least very weak, and the entire concept of "this race absolutely cannot be this class" is also a design I dislike.

EDIT X2: Also, +1d8 against arcane casters at first level is pretty powerful, while it's mostly worthless later on.
