We tried it again last night and accidntally killed the dragon so we are raid locked until next Tuesday. That means we have 1 week to figure out our strategy and become the masters of char-grilling some iron dwarves to perfection!
UPDATE: We were successful last night (09/29/16) using the following strategy!
Here's the gist of what we need to do to gain this cheevo:
- Collect iron dwarves
Damage the iron dwarves a little- We verified last night that this is not needed
- Harpoon Razorscale
- Damage Razorscale < 50% so she stays grounded - Again, difficult because of the damage we do. A new guildie last night had a great idea. She took off all of her gear and just melee'd her and that was working quite well!
- Bunch the dwarves up and let Razorscale slowly roast them! - This takes 8-10 breaths? This is a good time to step away form the computer and let her do her thing.
- Run up the stairs to reset the fight - If anything goes wrong other than killing Razorscale.
Here's a new vid I just found: (in this one he didn't actually damage the iron dwarves!)
