Wiki says: Calm before Storms: +3/6/10 Spell Resistance. Rank 3: You no longer fail Will saves automatically on a roll of 1.
1) Earthgrab is Will save? I don't think so.
2) Are your saving throws high enough? The ability does not make you autosucceed on 1s, but it simply will not autofail. Your total must still be higher than the ability DC.
