Hey Gamers! Welcome to Scalecaller Peak, which is part of the Dragon Bones DLC in Elder Scrolls Online!
Below is a video that will discuss all the boss mechanics and everything you need to know to beat this dungeon!
**Of note, the video is done on Veteran difficulty, but you only need to play on NORMAL for this particular achievement; however, if you are trying to get the achievements there is a separate achievement for beating this and Fang Lair on Veteran so this video should help you beat it on veteran. Also, the final fight is done on Hard Mode (reading the scroll), which is also not necessary for the achievement, but I want the video to discuss all the possible mechanics of this dungeon, which includes hard mode.
I hope you find the video helpful!
