Enveloping Shadows - Very useful, in PvE and PvP
settings. Topped with Heightened Senses, you can generally avoid any
AoE attack 19% of the time, without adding together your resistance gear.
This includes PvE boss encounters, PvP
encounters with Frost Nova, Arcane Explosion, Blast Wave, War Stomp,
Fears, etc. It can really screw up an enemy player when you resist an
attack they usually rely on to when.
