casting the spell swarm, a level 1 nature spell requiring 1 gem that, iirc produces 20 weak dragonflys or something like that. Using it with undead archers you can get some (practically free) chaff that it dosnt matter if your archers hit or not (since they die after battle)

Yes, I know what these both seplls are. I was curious about the synergy between them.

I understand your point, and I agree that swarm is a nice delaying spell. But how is this combo (with undead archers) different from using swarm with any other deadly missile attack? Like for example "normal archers with fire arrows"/"swarm" combo?
