Burn It to the Ground

more like burn it to the gorground! anyone...? okay....

Obtaining this achievement is only possible when you have the Assault on the Everbloom Wilds daily quest from your Garrison because you are unable to interact with the objects without it.

There are Iron Pyrotech corpses scattered around Everbloom Wilds which grant you a Blackrock Flamethrower when you interact with them. The flamethrower starts with 100% fuel and is activated using the button in the middle of your screen (ExtraActionButton1). Once you activate the flamethrower you become slowed, 20% of the fuel gets used up and a 5 second channel starts during which you can move close to trees and burn them. You are still able to use your own abilities during the channel.

There is no need to reset the quest, just make sure you are in a raid group. You won't get credit towards the quest but you will get credit towards the achievement. :)
