Guild Wars 2

Can any of you suggest a good build/strategy for beating Strugar&Chomper ?

I have tried a couple of different strategies but I can’t seem to get it.
Plus, it might be fun to try a new build

autoattack the dog. when he throws first meat, shield bash the dog then go for the meat. keep autoattacking dog. when he throws second meat, fearme the dog, get the meat, swap to hammer. when you see him throw 3rd meat, hammer 4 then 5 the dog. get the meat. by then the dog should be at no health. kill the dog then kill the guy.

this is also guaranteed way to get the achievement. 100% success rate.

use sword to leap to meat if it’s far away after stunning/fearing the dog
