Yeah, ya cant split his companions...they move just as fast as he does and he makes a nice round loop runnin around the edges o' the goblin area..and he does hit hard..very hard..but ya do have time to heal yourself or your pet or have yer friends or mercs heal you..he doesnt stun often...unless yer too low level..oh and I couldnt snare this mob either
