Goliath Offline

'Goliath Offline' is a bit of a parody compared to the "Goliath Online" we first heard in Starcraft, as revealed here: https://youtu.be/g1TIckYZLKM?si=uBCAxXWtPaVv1pvn&t=27
Anyways, down to business.

Relatively Easy Solo Achievement for Level 70 Dragonflight & Beyond...

1) Mythic Difficulty.

2) Achievement can be tracked, requirements will turn from Red to White upon satisfaction.

3) Clear all trash in the area, you don't need that stuff messing around while you're doing the achievement.

4) Take note of the three Shattered Devastators in the area, two of them are close together which is awesome.

5) Pull Oryphrion.

6) Eventually Oryph will put a blue arrow over your head, stack the Shattered Devastator that is closest to a second Shattered Devastator.

7) Minimal damage to boss

8) Eventually Oryph will place yet another blue arrow over your head, stack the second Shattered Devastator.

9) Now you get to avoid stuff on the ground and wait for Oryph to Recharge Anima, stay in the area of the two Shattered Devastators, it takes a while...

10) Once Oryph is recharging anima, you'll notice two of the Shattered Devastators have woken up when the blue orbs go flying about the area, kill them asap.

11) Head to the third and final Shattered Devastator, once you get the blue arrow on you stack it.

12) Wait again for Recharging Anima, all the while avoiding stuff on the ground.

13) Once the final Shattered Devastator has woken up, kill it.

14) With the achievement requirement now satisfied, nuke the boss.

15) ?

16) Profit. Achievement Completed.

Took me a while to realize that the boss isn't allowed to stand in the blue puddles. So you gotta kite him out.
Otherwise, his power won't go down = he won't trigger the mechs needed for the achievement.

Goliath Offline (3rd boss - Oryphrion)
-------------------------
Video with short voice-over guide.

- Clear all trash in the boss room
- There are 3 spread out Shattered Devastator mobs spread out in this room (they are inactive)
- Stack on these mobs when the boss casts [spell=324444]
- The swirly you drop will power the golem when the boss enters the [spell=324046] Phase.
- The golems only last 30 seconds, kill them quickly, they have 128k hp
For this reason, choose to do them one at a time or multiple depending on your groups capabilities.
