It's for my Steampunk game idea inspired on Eldritch horror. Each turn, 2 type of encounters are spawned on the board adding threat to the area. Players can complete those encounter to make the game progress in their favor and remove the threat from the board.
I currently have 4 broad categories of encounters, I need a 5th one. It needs to be something that the players can solve. Something that undo the demon's objective in order to win. So far, I have the following type with possible common special effects:
Rifts: Gates to other world that spawn additional monsters and allow astra travel. Players can close those rift.
Mysteries: Suspicious activities or events occurring the area. Add a special rule to the area. Players can attempt to eradicate the source of the mystery.
Worshipers: Cultist doing rituals and other nasty things in the area. Makes other event surge more easily. Players can try to eliminate or sabotage those worshipers.
Doom/Disaster: This cannot be undone, add a special effect permanently. This is what makes the game more difficult and less repetitive over time.
Now I need a fifth one, I looked at Eldritch Horror for inspiration but could not really found anything.
Rumors: Are similar to disaster or mysteries. They are abnormal population behavior, could be hard to undo since it affects many people.
There will also have world encounters which can be explored by the players, but they do not help the demon wins.
So I am actually thinking, what else could a demon do?
They could corrupt people to do their bidding, feels very much like worshipers.
There are already artifacts. They are part of the World Encounters that yield assets to upgrade characters. I need something for the demon encounters.
On BGG, somebody suggested having some sort of barriers. It can be anything that prevent the players from attempting other encounters in the area. They must clear the barrier encounter first, then they can clear other encounters.
I think I like the idea, and it's vague enough to offer different thematic possibilities.
