For some reason or another, my drow's spell resistance isn't adding up to 11+ class level.

Due to a BioWare bug, you'll only get increases to your SR every odd level. It sucks, but it is here to stay. :/

You're not getting it at all (unless you're not supposed to get it before level 5). Are you equipping the drow skin when you log in?

[Edit] Nope, something isn't right.

Yeah, the drow hide is equipped on log-on.

It is hardcoded sir Snoteye.

Yeah, I was looking at EFUSL. It seems it only registers SR when the character is logged out.

You are nuts, sir Snoteye.

When you say sir, I feel all important-like. =)
