(if you're on normal diff)
"Choke Point" and "Firewall" (I'm a little rusty with Diablo knowledge, so if Steel Lords are immune to fire or whatever then, Whoops)
Example choke points
X= one of those stalagtite things (or a chest/barrel)
And just lay a firewall down right in front of you.
If your in multiplayer and 'havn't' Died then you can always just new game (which by now you have)
If your dead in multiplayer you could lead them away (doen't matter, because I'm writing this 4 days later)
If its single you can always just reload and be more careful, so as not to wake ALL of them up.
