I was wondering if anyone can tell me what weapons Barin can use? I also need a good freezer. He's having a hard time beating Greasy Joe

You can preview Joe's attacks over here. What tier are you?

No need to blast or steal, focus on defence and healing yourself. Find which of your weapons do the most earth/fire/dark defence.

Cobalt Eternal would be the perfect scroll, if you have multiples that's even better, those icons are pretty common so it's a good investment.
