Anomander is correct. Chronopia does not have the equivalent of Minimize Presence that you find in Warzone.
Though perhaps that is something that might be worth looking into, as I think it's more than a valid tactic, especially, as you pointed out, the alternative might be getting turned into a nice, Dwarvy pin-cushion....
But, you must admit, the picture would be rather cute though....
Heh heh....
