To kill it you must use a level 80 plus creature that has a projectile attack or breath attack like a wyvern I killed like 30 with a level 120 poison wyvern it was pretty fun too or you can just use brute for and use a bunch of low level rexes with a yuty. A pack of 20 low level dire wolves will take it out in 10 seconds but there's a small chance one will die
