Rift powerleveling (alts) using Mass Charged Shield

[Helza]

Taken from Dumfawks twitch stream:

If you or an friend have an level 60 Dominator Mage you can cast Mass Charged Shield on your party/raid giving all players the Mass Charged Shield buff for 1hour

Mass Charged Shield
Creates a shield of energy around all group and raid members within 35 meters for 1 hour, causing x to xAir damage to attackers damaging the affected ally. Can occur up to 1 time every second. This counts as an Armor buff. Only 1 Armor may be active at a time. Will not affect allies with an existing Armor buff.

Unlike some other game where buffs casted on players which will be scaled by player level, this buff is an fixed number and will not scale (down), allowing you to kill mobs pretty quickly

(at level 40 he gained around 3 levels an hours)

All you have to do is stay alive, which becomes pretty easy if your an Cleric using Sentinel / Purifier /Warden tree
