Yes use the Ancient Cavern (where the Mith Drags are) and not the Chaos Tunnels. You will get slaughtered in multi. When you get in run South West and theres a spawn of 3 with no other monsters nearby. After 20 mins you can go a bit further North as the Skeleton will be non-aggro. Don't go east to the Brutal Greens, they hit hard. Thank you, I'm there now, hammering those pesky fiends. Doing fine with Bunyip btw!
