You can kill all 4 rather easily using a 3 character party with multiplayer getting laezal and the brain. Even without cheesing just by throwing the oil cans and blowing them up repeatedly on the mindflyer and devil commander you cna kill both taking little to no damage then kill the cambions as they show up 1v1 with 1 character picking up the fallen character if they drop. Easy to reach level 2 before leaving the ship. Not really cheese required since they only attack 1 character per round its just an actual valid way of doing it.
