looking for tactical advice

[Wish]

in dom 2 there was a two handed artifact that did around 100 damage. that one got taken out of the game, it appears.

If you have nature mages, there's that relatively low-level spell that creates swarms of maggots. Each casting costs a nature gem, but if you can find a whole lot of nature mages and give them each a gem, it really eats up undead.

I don't usually have too many problems with undead though. I use a lot of priests in the back of my army, set to cast banishment 5 times each.
