The lift that leads you to the first bell tower, from Firelink shrine...drop down the side of the lift that isn't there. Follow it through and there'll be 4 treasure chests. 1 has 4 cracked red orbs or whatever they're called.
Go back to the Undead Asylum and trade 1 of those cracked red orbs with Snuggly. (if you dunno how to do that you're gonna need a video tutorial or someone better than I at explaining). Snuggly gives 2 curse curing things for one of them I believe. The wiki says it's a Resist Curse Stone, but the translations are off and I honestly don't know the name of the curse curing item, lol.
