I can garantee you that it adds untop of MoH and ToA Healing bonus on spreadheals. It does not work on any other heals for the group then spreadheals, it does work however on heals you cast on yourself, so lets say with group insta the insta that hits you have effect.
What the last resist is I can not say, simply because my flask isn't high enough level yet
Can not be done anymore with sojourner, so requires much more people these days.
Well, fook it I guess, Statuesque Eye instead. B.t.w I didn't even know it was doable with sojo before, I've done the enc once and ran like hell. Also failed a couple of times when not enough people. Well, thanks for info.
And yes it was (?) doable in 2 ppl but it wasn't easy at all. Afair we spend a few hours (5-7 tries overall) to get the jewel and Krom did it alone playing 2 chars and he's been cursing in /gu and on vent like hell ;p
