How does Drow Spell Resistance work these days? I have not played a Drow in almost a decade. What I remember is that they got a spell resistance equal to 10 + character level (so 11 SR at level 1 and 30 SR at level 20). I just looked at the Drow Race on the DDO Wiki and all I see is that Drow get SR 6. Is that it? They start with 6 SR at level 1 and still only have 6 SR at level 20? I see you can get +2 SR three times in the core stats (so a total of an addition 6 SR if you spend 7 points in the racial core), but that would still only be 12 SR at level 20 (which is such a uselessly low number that it would never take effect).
Am I missing something? Is there more than just this 12 Spell Resistance? If there is only this 12, does it at least stack with items (so an item that gives SR 29 would result in 41 SR if you took the full +12 SR from being a drow)?
