Siege weapons

[Wrana]

Well, it's one of the main tasks of the sieging army to construct them! So you can just assume that they are doing so offstage.

To Sombre:
Unfortunately, while thinking on the future Warhammer project I found no equivalent to Warhammer cannons with their non-circular area of effect. Did you think on these?

[Dedas]

I mean you can use those siege engines in combat after they've been constructed.

On the topic of battlefield artillery, as opposed to a pure seige weapon - mages are effectively the battlefield artillery of Dominions

[Wrana]

Well, the above-mentioned Warhammer Fantasy Battle has both, though its magic is somewhat weaker than that in the Dominions, and SC are exception there...
