if u had 3 units on night goblins with nets, and u used em on a unit of dwarfs, reducing their strength to '0' it kills the whole squad (as said in page 5 3rd paragraph down of the warhammer rulebook), is this an efficient way of killing stuff? ^_^

It would work...except that they errata'd that units can only be netted once. See this discussion.

Also, it would probably be kinda difficult to set that one up. Could be funny if he had a lot of points in that unit, though.

lol yea, shame about the errata, thanks anyway
