Hey Gamers! Welcome to the Horns of the Reach DLC in Elder Scrolls Online. This achievement is for completing bloodroot forge on Normal difficulty.
Here is a video guide that will cover the mechanics of all the bosses in this dungeon. The video is actually done on Veteran mode, so you can use this too for your veteran playthrough, and as you can imagine the bosses will be even easier than shown in the video; however, the video will cover all the mechanics you need to know!
I hope this is helpful!
