03/22 - Flame Leviathan Testing
The testing of Flame Leviathan is now active on both US and EU PTR Realms. It looks like it will be the last boss test before the next PTR build.

Testing has been cancelled ... Well, that was a short one.

Fight Information
Flame Leviathan Health - 20M (10-Man) / 62M (25-Man)

Every 30 seconds he will switch targets to another siege vehicle, mark them, and follow them around. If you do not have two siege vehicles active then he will pick a different unit.

He has a soft enrange due to Gathering Speed. You have to kite him, thanks to Battering Ram, and it becomes harder and harder to get away from him even with help from Steam Rush.

• Flame Jets: Inflicts 2000 Fire damage to enemies around the caster. 50 yard range. Interruptable.
• Battering Ram: a melee range attack, Rams the target, dealing damage and knocking it forward. Debuffs them with "Battering Ram": Damage taken increased by 100%.
• Gathering Speed: periodically he moves a bit faster by gaining another stack of this buff. The stack is reset when he is stunned by Overload Circuit.
• He also fires rockets constantly at the raid, doing about 700 damage each time they land (about once every 1-2 seconds)
• He has 4 turrets. Passengers in the demolisher can be launched at him where they can destroy the turrets and then hit the Overload Circuit: stuns Flame Leviathan and causes him to take 50% more damage for 10 seconds.

Player Vehicles
The vehicles have a base HP that then increases based on the ilvl of your gear (tip: stop DE'ing trash epics with high ilevels and save them for Ulduar!)

Salvaged Siege Engine
This vehicle demolishes towers as you clear the gauntlet and kites the Flame Leviathan. It can carry a passenger.

Salvaged Demolisher
This vehicle moves slowly but has ranged attacks and can even catapult its passengers. It can carry a passenger, who can grapple the pyrites from the ground and loads them one by one as abilities that deplete them are used. The primary use for them is giving 10 charges to the big nuke.

Salvaged Chopper
This motorcycle model is very fast and moves very adroitly (it can strafe, for example.) It can carry a passenger.

• Sonic Horn: Instant, 20 energy. Sends a wave of force in front of the motorcycle, causing 3150 to 3850 damage to all enemy targets within 35 yards in a frontal cone.

• Speed Boost: Instant, 50 energy. Fires the fuel injectors on the bike, increasing its speed by 100% for 5 seconds. (no cooldown)

Fight Strategy
Just read the StratsFu Strategy Guide.

Do they even test that stuff internally? You cannot kill turrets, so you cannot stun him and reset the speed buff.
There also seems to be some bugs with the pyrite itself.
Further does he get the orbital buff on engage with +0% dmg/hp but he still gains roughly 10milhp ( no towers destroyed).
Also after killing him that way (0 Towers destroyed) we got the achievement for 4 tower hardmode and that normal mode is just boring and way to easy.
Last week with stuns we destroyed him in under 1 minute.

I have a screencap of the announcement on Anasterian (US PvP): testing cancelled.

At least they finally figured out what raiding resto shaman want their relics to look like.

Flame Leviathan 25man - Kill

Quite bugged encounter.
This was supposed to be hard mode, though it diden't work correctly.
We got all 5 achievements none the less though!
