Congrats OP.

A year ago we built up the ground around him so he couldn't get out of his circle. We just peppered him with arrows over a period of time until he finally died.

A year later I'm going it completely solo and I've put a few hundred hours back into the game. I've dedicated some time into breeding 2-star wolves. I sailed a few over to where Yagluth is and now I'm breeding more. I'll probably get up to about 30 wolves and try to tame a few Lox also. Then I'll let them have at him. I'll finish him off with some melee if they aren't able to get it done. It's more enjoyable taking the slow pace this time around though and just having some fun with the animals that I didn't the first time through.
