Overall, I like the unique mechanics, like the horned skulls, but the more normal mechanics are a bit lackluster, and they feel a bit weak.
Past the spelling errors, the horned skull recruitment is awesome, but you can't do enough of it. If anyone is actually spending their actions to destroy your skulls, your recruitment won't be able to match your need for warriors and battles to build pens, as well as the recruitment you need to sacrifice to get goat pens. I would add some way to get goat warriors besides the horned skulls, on the same turn, so you can't be easily wiped off the map. That or it needs to be easier to make horned skulls on your turn, as each one currently requires a card. Maybe for the Second Wave, make it 2+1 per card, to give a little more strength and choice to recruitment and battles outside salted clearings. Also, as they take extra hits while attacking the salted clearings, they will need those extra troops just to live. Also make the damned charge clearer, I think just make it clear that they can choose to move and/or attack, not needing to do both.
I actually really like the salted clearings and specifically how you encourage the goats to play around them through the built in mechanics, encouraging them to go and fight in them, then sacrifice the dead warriors to make pens, so that the rest of the warriors don't die, and you get VP, as well as the rams which help you as you move into new clearings and battle, while also giving other factions a chance at countering/playing around them. I would make crafting just any goat pen NOT in a salted clearing, as you aren't likely to have many goat pens in the currently salted clearings.
Overall the scoring seems actually very balanced, mostly because they are going to be eating cardboard across the board as they attack the salted clearings, so the lackluster scoring in rest for the damned will be mitigated by that.
Overall, a very good idea, with unique recruitment and I love the salted clearings and how the herd is encouraged to attack them for the vp, despite taking extra hits. Definitely look over the spellings, and help their action economy, specifically with recruitment, and MAYBE, maybe help their vp scoring, if its needed after playtests
