I've tried several times now to beat Aryth (the triple version of him) but each time I can only get one of them down, and even then I have to use several potions. All my pets are level 50 or more (ok well, one is 51), have good equipment (not all epics and such but best numbers for their build), and I have used the tank/mage/warrior set up. What am I doing wrong here?

*note* I have had little trouble up until this point, so being stuck seems odd

That was the first one I really had a challenge with, too.
My answer to it was to stat my pets up a bit, hoard potions like a crazy woman, and then go back.
And then I crushed him. It only gets harder from here on in though, I swear. You might want to look at upgrading your armor to the best you can get, too. It makes a big difference.

I had no issues, then again I came in with about 20 of each potion, pets had oranges or purples equips, and I had over 100 revivals, still do. for some reason sylestia thinks I need revivals pots.

I'm not sure about upgrading my armor cause all if the epic and such I have found had really low numbers compared to the ones Im using. I may try again with more potions though.
