Shadows: Awakening

]For this achievement you must have reached the outlands once there go to the nearest cenotaph and TP back to Thole marketplace once there go to speak with arashad after a brief conversation you will receive the quest "scorpion king" once you have it head to the east side of the outlands to find the scorpions caves a quest marker leads the way so extremely easy to find after a few puzzles you come to the fight this boss was actually quite tough and I died 1st time im playing on hard and he is very tanky does high damage and has 7150HP! but slow and until down to half health his only two attacks are his main which he thrusts his barbed poisonous tail at you causing big damage and poisoning you and his other attack is to leave a trail of poison gas behind himself as he trundles about !....after hitting half health he then uses a ranged AOE attack where he spits 3 puddles of venom 1 of which nearly always seems to hit but the damage is minimal....how I beat it was 1st use the devourer to freeze the maggots that have spawned around you clear those 1st as no more spawn once cleared I just went to my sniper and spammed arrows until he got close switch to devourer run to the other side …….and that's that even when he starts spitting at you just switch move then spam the arrows ….. job done cheevo pops nice and easy

hope this helps
