Let Me Solo Him: The Underpin

Completed tonight as a 661 Destro warlock.

Tips:

• 
  
• Brann as a healer is a necessity. With the changes made to Brann, he seems to never die from any AOE he is standing in and lived for each attempt.
• 
  
• I did not reset the instance after each attempt.
• 
  
• I used Rank 2 Impact Conversion Matrix and the Rank 2 biofuel rocket gear. I think Lootraidr could be used for 4% more damage to the underpin could be useful but i wouldnt use anything else in the utility slot.
• 
  
• Use the Interact Keybind that Blizzard has given us in the UI. This is necessary to ensure you are kicking bombs quickly and effectively.
• 
  
• I had the most success with ensuring that every single crony was killed each set. If even one Crony is up and left over, it can get out of control pretty quickly.
• 
  
• Practice just kicking the bombs to hit as many as you can and healing off the boss with drain life/whatever your class has. Do 3-4 minutes of not hitting the boss and just doing crony attempts.
• 
  
• Just like everyone else has and will mention: saving something to break the shield he puts up every 10% is crucial. If one heal gets off its too disheartening to continue the attempt IMO.
• 
  
• I didn't use lust (drums as warlock) because it wasn't necessary.
• 
  
• This probably could be done at a lower ilevel maybe 650 but without 2/4 piece you are just making this more difficult to break that shield.
• 
  
• All of your attempts that go "deep" that have deaths will likely be due to either flamethrower, or a fire ball from a crony knocking you into a flamethrower. It is outrangeable so if you can shmove away from the boss now's your chance to run.
• 
  
• Do not give up on this challenge. Everything that killed me on my attempts felt 'fair'. Nothing becomes a surprise if you can live for 4-5 minutes. My killtime was 7 minutes 32 seconds. I'm sure you can do it faster than that.
• 
  
• When the boss hit 6% HP, I had 2 cronies up on seperate sides of the room and just tunneled. Felt worth it at that point.
• 
  

Good Luck :D

I hate this fight and everyone involved in designing it.

The fact that it's been almost a week and this achievement still doesn't give the schematic is criminal. People are spending hours slogging through a buggy, broken fight with Brann trolling the positioning of the boss and dying nearly instantly when a tank/healer just to not get the schematic. Same thing happened to me. Have the achievement, but no golden gob trotter.

Finally gave me the reward on logging in. Available at the rostrum with no appearance collected/learned notification.
