Raszageth the Storm-Eater is the final boss of Vault of the Incarnates and notably drops Tier Set tokens for the Helm armor slot as well as the unique bow Neltharax, Enemy of the Sky which has a higher item level than the rest of her loot. Raszageth the Storm-Eater drops high item level loot: 385 (LFR), 398 (Normal), 411 (Heroic), 424 (Mythic). She also drops the Dragonriding customization option Renewed Proto-Drake: Embodiment of the Storm-Eater on Normal difficulty and up. 

This is a three phased fight with two intermissions. Raszageth has several storm and lightning themed abilities that will try to kill players before they are able to defeat her. During the intermissions, your raid will be fighting various reinforcements summoned by Raszaageth to weaken The Vault of the Incarnates.

Phase 2:

• Watch for pushback/damage wave from Tempest Wing.

• Fulminating Charge - debuff that slows and then jumps .. everyone without the debuff run away!  May have to bait by having ranged "buddy" stay with person that has the debuff.

• Volatile current .. same as before.  CC/Int adds.

• Stormsurge - shield on boss.  Break asap.

• Stormcharged buff - positive or negative .. stack with same charge.

Intermission 2:

• Kill big add.  

• Little adds will spawn after he teleports .. CC/slow and kill them before they reach the big add.

• When big add dies, there's a large knockback .. use that to get knocked back onto the first platform.

Phase 3:

• Similar to Phase 2, only with a platform that is slowly reducing in useable size.

• Thunderous Blast - huge damage, whatever tank takes is reflected to raid - use mitigation and raid heals.  Tank swap after.

HEROIC:

• P1: Volatile Spark adds now need to be interrupted TWICE each time.

• Intermission 1: Spread with debuff (blue rings).

• P2: +/- charges .. don't touch opposite charge - AoE damage.

• Intermission 2: Two Stormfiends instead of just one, must die at the same time.  Split raid into two, nuke adds as they cross paths.

• P3: Magnetic charge (big blue circle) - after 8 secs raid gets pulled to them, doing damage reduced by distance pulled - run away.  Be careful not to be pulled through breath, etc.
