Yeah thats so they stay compatible with each other. It's been long so im not sure but I think this one might still work without the other. Maybe you could test that out in a small map real quick?

i see that does sound cool. i was just confused since it required what seems like a spell mod

@Yikes you know how a fortress protects all tiles around it? Now most structures do this. So if for instance you are attacked next to a gold mine, you will fight in that gold mine

what does this do?

This is splendid if it works as I think it does, and if you ever get into Planetfall modding, you should add this to that.
