Cadary and I have invaded the Kingdom Newbular. We defeated their champion once, but lost a second time so we retreated. We were able to take control of one block of land and used it to clear the building on that block. We unclaimed that block of land after we were done.
We also invaded BaconGods, their champion is super easy to defeat. Took control of half their land and then unclaimed after we took what we found useful.
