Orbital Devastation (25 player)

Kill the Flame Leviathan on the second tier of hard mode on heroic difficulty.

There are 4 defence towers in the gauntlet leading to the Flame Leviathan which can be activated by talking to the Lore Keeper of Norgannon before talking to Brann to start the gauntlet. Activating a tower and leaving it intact will activate a unique Orbital Defense System on the Leviathan. Each Defense System grants the Leviathan an extra ability, increases his health by 50% (multiplicative!), gives him a unique buff, converts all dropped Emblems of Valor to Emblems of Conquest and increases the number of Emblems. Killing the Leviathan with 2 Defence Systems active is the second tier of hard mode and allows the raid to get the Heroic: Orbital Devastation achievement and 2 Emblems of Conquest.

The Leviathan gains 125% HP and two of the following abilities when 2 Defense Systems are active:

• Tower of Storms: Thorim's Hammer - Physical damage. Extra damage at point of impact. Also increases physical damage by 25%
• 
  
• Tower of Flames: Mimiron's Inferno - Fire damage and a AoE damage zone. Also increases fire damage by 50%
• 
  
• Tower of Frost: Hodir's Fury - Frost damage and entombs vehicles near the impact point in ice. Entombed vehicles are stunned for 1 minute, taking damage over time. The tomb can be destroyed with ignited Tar. Also slows players for 20%
• 
  
• Tower of Nature: Freya's Ward - Nature damage and summons Writhing Lasher and Ward of Life adds. Also descreases fire damage taken by Leviathan by 10%

HP and loot results of leaving up fewer towers with Hard Mode active:
0 Towers | 1 Towers | 2 Towers | 3 Towers | 4 Towers
HP [mln] 70 | 105 | 158 | 236 | 354
Emblems 1 | 2 | 2 | 3 | 3
Loot normal | normal | normal | normal | Normal + hard

566 Shadow Priest and was able to SOLO the 25 man version (Storms and Life) (Frost and Fire being down because Frost one shot vehicles and the fire aoe on the ground)

i think it might be possible to Solo this with 3 towers (frost being down) but that would be extremely difficult to do

If you going for the 3 towers up ... you must absolutely extend the time from 8 to 9 stacks and 9 to 10 stacks to be able to maximize your damage, same thing on the second demolisher, and same thing on the third demolisher, and etc ...

But like i said, 3T up seem impossible

The tactic ... is obviously quite simple

The goal for the first 2 one is to spam the fudge up the pyrite bomb asap (till it's empty) and quickly jump to the second and do the same thing and etc to all of them

It COULD BE possible to solo this (like mentioned earlier) with 3 towers up (frost beign down because the effect is, as you don't know, do a vertical beam and will most likely destroy your demolisher

Life adds is easy to down
Storm should be easy to dodge as well
Fire is RNG side so hope for ya that is going well

But for the 3 towers up .. you need to spread more the demolisher .. because of the fire tower effect

obviously, a movement speed buff is probably NECESSSARY for this... because at the end of Demolisher#1, Flame Leviathan will be at your demolisher (obviously) and when your pyrite is down or the demolisher being destroy,, the chance that if you fall to your , by example, as i use, angelic feather, you could be

A) right go on the ground and get angelic feather and run to the next one or...
B) get smack A.K.A Knockback by "him" and making a vital 1 or 2 second of DPS

During the Demolisher part...you should spam it as usual .. but stop at the stack of 9... wait till it does damage , or until you are near to break, then throw the next pyrite bomb, and repeat...

the goal here is that the stack#9 do extra damage, so be patient and calculate your time is vital for this(i mgiht be too repetitive with my words here and i apologize for it)

Bold/Italic/UnderLine the impotant and the difference between 2 and 3 towers up

PS: With 2 towers up (Life and Storms) i could finish Leviathan (obviously solo) within the pyrite#4 or #5 so i thought that if i wait for pyrite#9 to do extra damage
... it could POSSIBLY do the extra 40-50% health of the (0 towers up)70m*50%=(1 tower up)105m*50%=(2 towers up)158m*50%=(3 towers up)236m*50%=(4 towers up)354m health ( Thanks for the number of Maliander made in his/her comment)

As you can see ... the difference in numbers A.K.A 236-158=78 millions health ... that is more than 0 towers up

This wall of text is just a THEORY (not sure if theory is the right word) of the possibility of SOLOing 3 towers up (Frost being down)

Will update this as soon as i can try this theory.
