1) Log in to a Scourge Warlock
2) Slot Infernal Spheres as one of your Encounter Powers
3) Head to any zone PvP Area
4) Slot a weapon enchantment other than the dread (Prominence works best)
5) Activate Infernal Spheres
^) While Infernal Spheres is active on the Player, any DMG they take multiproc's the weapon enchantment.
After activating Infernal Spheres the weapon enchantment (Prominence) Proc'd about 103 times resulting in the SW being invincible from the heals of infernal spheres as well as the weapon enchantment killing anyone that attacks.
Infernal spheres should NOT multiproc on each strike of the encounter Infernal Spheres and should only Proc 1 -time on the activation of Infernal Spheres.
