I recently reached level 30 in my Holy Curing skill, and got a message saying I now resist Blindness and Poison. The Guide and Skill Builder also indicate I should have received these intrinsic resistances, yet my character sheet doesn't show them, and I can still be blinded(but not poisoned, courtesy of a pair of Mirkwoods I've had since Dungeon Keeper - however, the poison resistance also doesn't appear on the player column of my character sheet).
Edit: Disregard, I was simply misreading the guide.
