So A buddy of my brought up the idea of trying to use the Jcer necks. There are several different necks that allow you to buff your group. Some of the better buffs are

+20 stam
+34 spell damage
+10 to all stats
+2% crit

for 30 mins

It would be really crazy if any of these buffs stack with themselves. I think tonight I have some experimenting to do. Anyone tried this?
