Magnify... Enhance

Easy Achievement in Battle for Azeroth Level 120 and beyond...

1. Heroic Difficulty

2. Once on High Sage Viryx's platform, head to the far east corner

3. Start fight, and only damage boss a little, say 25% at the very least.

4. Eventually a bird is going to pick you up, wait for it to carry you just over the edge of the platform.

5. Kill the bird that picked you up.

6. You will fall to a lower platform. The construct will assemble.

7. Kill the construct ASAP.

8. ?

9a. Profit. Achievement Completed.

Okay, this is probably the most wierd achievement I've done, but here it goes.

To do this you have to reach the last boss.

Before you start the boss, you go to the right of the boss (Looking towards the boss) and you'll see a small platform.
On that platform there's a small construct that is inactive, which you have to activate by running [Lens Flare] over it.

So before engaging the boss, send one guy down on the platform. The other 4 people go ahead and do the boss, as soon as the guy on the platform gets the [Lens Flare] it's going to activate the add and spawn the Empowered Construct.

Then just kill the boss, ress the guy and kill the add.

To clarify:

1. 
   
2. Get to Last boss
3. 
   
4. Get one guy on the small platform
5. 
   
6. Kill the boss slowly while making sure the add gets activated
7. 
   
8. Spawn add
9. 
   
10. Kill boss
11. 
    
12. Jump down, kill add
13. 
    
14. Done
15.

If you are soloing this at lvl 110, just DPS boss slowly until her beam comes out (Great Spire's Focusing Iris) then just drop over the edge of the platform (carefully!) to the construct platform below. The beam will follow you down and once you get the Lens Flare debuff from the beam the construct will activate. Kill the construct to get the achievement. Easy as.
