Similar to caravans, but instead of serving the purpose of hauling goods it is made for offensive and defensive purpose.
The war wagon could work using the caravan's mechanics, Components however could be switched out to give more health to the wagon, protection to its occupants, and maybe even a means of using siege like weapons as spells for a raid. The possibilities!
Have some really expensive stuff in a caravan that needs that extra bit of protection?
Why not deploy one or two war wagons to give bandits that extra bit of pause before they think about attacking.
Or maybe you are the bandits and you need to deploy a barrier to stop that caravan and you got the resources to do it.
Tumok giving you trouble? Ballistas! But you might want to be quick to get going because those wagons might become a liability too.
What do you guys think?
