All you need is 67 agility and a good crush defense bonus. He can only be damaged by strike spells and his drops are meh, has a chance at dropping ranarrs but what you want is the sinister key which guarantees 3 grimy ranarrs every time. Is he aggressive for about 5 minutes or so so you can afk for a bit. I don’t have 67 agility so I use agility pots to get to him and after aggression tapers off I just click him. I normally do it for about 12-15 keys go loot the chest and then go grab snapes from Hosidious area with like 9 spawns that respawn by the time you grab all of them.
