I love this. The Chitinbane being in the game seems like it would add another level of drama, hordes amassing in the forest as a desperate company of armadillos races across the board to set up countermeasures and take down the beasts.
I feel like you could have given some more words to the schedule action as it's (by my understanding) a little strange and you have the extra space. I do wish the swarm was a bit less passive because you need outposts all across the board to score points, but opponents worried about about the swarm will have a better time stopping you from keeping any bait rather than letting you set up in a clearing.
