I have libram of uther and the holy shield one as well,
Any help would be great
thanks

personally the 4% spell damage reduction wont be that useful from what i have been told by other end game tanks. you could drop the 2 points from that and put them into reckoning OR you could drop the 2 from that and 1 from improved judgement and put it into improved SoC

we got a ret pally who attends every raid, should have said that, his always in melee group so his aura is not gonna help.

I could try reck, thats a good idea i didnt think bout.
Thanks Gustov
