Siege weapons

[Professor_Dyar]

There are siege weapons in the game. They just are "off-stage".

The rationale is that the reducing power of an army besieging a fortress represents the ability of the attacking army to build siege engines to level the fortress' walls, while the defensive power represents the ability to repair the walls. Engineer units are particularly good at designing powerful siege engines, or well-constructed walls, which is why they get a bonus.

It has nothing to do with magic.
