First u need a negate mud/snow armor skill. With it, you won't be covered in mud when he does it mud attacks You cans :
- Either use the full rhenoplos armor
- Use whatever combination u prefer but make sure u have a talisman with negate mud/snow and the correct decoration so that the sum of all negate mud/snow is more than ten => then u got the skill
- I had a lot of problem with this one, then I tried using Sword and Shield. Barroth covers in mud, when mudded, he is weak to water element. When you slash him ebough, the mud goes off and then he is more weak to fire.
- try to bring a few traps
Imho the best thing is to go around him, then wait for an oppening to give him a few slashes, then get off its way, repeat operation. It's easy to write, but u have to do it a few time before timing perfectly its attacks.
good luck !
