[FIXED] [Shaman][Elemental] Chain Lightning and Lava Beam Mastery procs

[Dreadblade]

WoW Freakz spell link: Chain Lightning | Lava Beam | Mastery: Elemental Overload
Bug description: 1. Mastery procs from Chain Lightning and Lava Beam ignore all forms of damage reduction, including Resilience.
2. Sometimes the mastery procs can spawn a new chain resulting in 3 or more hits on the same target (this is NOT due to Echo of the Elements, I had no talents when testing). Check the second video for proof.
Proof:

2. 2 small hits on Dreadfists means that a new chain was spawned from either dummies. 3 or more hits means mastery either procced twice, or there were two chains + mastery.
