Seriously? You're going to have this as the end reward of the new saga quest?
Change the +20 water resist to +20 endurance and watch the credits roll in from planar unsocketers while having players feel rewarded for doing your new quest.
I'd be happy to take a full time pay-check and consult 2hrs/wk if you're really struggling on stuff like this.
(and for the idiots who will miss the point - yes, I know it's a copy of the one from the HK event)
