Stormlight Archives: The Desolations board game or smth.
10 Playable characters (The heralds), each with variable powers.
Difficulty is based on how close it takes place to the "Final" Desolation.
Something something, various fused in a stack, you have to defeat them all to win, stack size based on player count?
Perhaps incorporate player death somehow, gives a bonus of some kind?
That's about as far as I've gotten.
