Aetherian Archive is a base game 12-person trial located in Craglorn. It was one of the first three trials that was introduced into The Elder Scrolls Online with the Craglorn update in May 2014. Originally this trial was scaled to Veteran Rank 12 and only had a normal and a hardmode but was later updated with the One Tamriel update in October 2016 to include a Veteran version and increased to CP160 difficulty.
This trial has 4 bosses and has a normal and veteran difficulty along with the option to activate a last boss hardmode.
This guide will focus on the Tank role and the mechanics and strategies for successfully completing this trial.
