Hey,
So, just pushed a beta-branch update on steam. If it doesn't break anything too horrifically, it'll be in version 18 full.
Buffed a few abilities, made it slower to warm up after freezing. Definitely easier to get stuff done following a successful civil war now.
Gave an ability which allows you to just trade power for cold directly. Once you've reached 12% world cooling you can keep casting it whenever it cools down, to slowly eradicate all human life on the map. Not sure if it's OP or not. Definitely can't be stopped if you disable Lightbringer Ritual. Might rework it slightly such that it REQUIRES the Lightbringer Ritual to function. Maybe it can only be cast while the Ritual is being cast? Would be an amusing way to turn their weapon against them.
Also added in your suggested ability to temporarily block travel between locations. It's called Blizzard, and you can cast it on a location, then another, and any link between them will be out of service while the blizzard lasts. Also not sure how OP this is. It seems somewhat useful, but maybe there's some incredible strategy which can be used that I've not thought of yet. It only works in the snowy areas of the map, making it more useful as you progress along with your grand plan to freeze the world.
Hopefully this makes the Dark Name a bit more playable now, and able to stand alone as its own strategy and thing, not just a way to slightly reduce the number of cities your Unholy Flesh has to eat.
Thanks for the feedback, it really helps
