Tactics
Raid loosely spread on one side of the boss.
Tanks taunt swap after 2 stacks of Zephyr Slam (damage, knockback and dot).
Conductive spark - keep to yourself, don't spread it, let it expire after 15 seconds.
Avoid Whirlwinds.
Cyclone will pull you towards the boss. Avoid whirlwinds and stay out of melee range of boss.
Volatile Infuser adds need to be tanked.
Take one Infuser to outside edge and kill asap. Interrupt Diverted Essence. Watch out for knockback when it dies. Repeat with 2nd.
Heroic
Split the raid into two. Volatile Infusers now appear one on the boss platform, and one on one of the side platforms, with lots of little adds.
Use the knockback from the Volatile Infuser on the main platform to knock the first group onto the platform with the second Volatile Infuser. Keep it interrupted and kill all the adds asap, using the knockback from the Volatile Infuser to get back onto the main platform.
Whilst on the outer platform, you take ramping damage and gain a debuff meaning the groups have to take turns on the platforms.
