M.C., Hammered

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

1) Mythic Difficulty.

2) Begin fight.

3) You'll notice that Deuce is standing off to the left of the bosses.

4) Stand in between Deuce and the Gnomercy 4.U. and eventually his thrust will knock Deuce into the fight area.

5) Kite Deuce over to one of the piston hammers on the side, a little brown swirl begins and the hammer knocks Deuce on his little gnome head.

6) He's out cold, now nuke the bosses. The Platinum Pummeler may need a knock on the head by the piston hammer as well to take down his immunity and kill him off.

7) ?

8) Profit. Achievement Completed.

[npc=151654] is located a little to the left of the 2 bosses. on the ledge of the arena.
To get [npc=151654] into the arena, you need Gnomercy 4.U. to hit him with his [spell=283565] charge.
When [npc=151654] gets knocked into the arena, he will do a little shouting and become hostile after that. Now simply kite him to a [npc=153202] and wait for a brown swirl on the ground, indicating where the piston will hit, and make sure [npc=151654] is hit(He will get a debuff called Piston Smasher). As soon as he has been hit, you can go ahead and kill the bosses. The Achievement will pop a few seconds after the last of the bosses dies.

Do keep in mind that the [npc=153202] can be destroyed if it is charged by Gnomercy 4.U., and that you can kill The Platinum Pummeler before doing the achievement.

Good luck with the achievement! :)

So, do not use the first Thrust on Deuce, it'll knock him at an angle and get him stuck. Get Gnomercy into the center and use the 2nd thrust to knock Deuce directly back, then it'll push him out into the arena.
