As players become more experienced, they might find the skull fortress raids to be a bit too easy, to the point that they're boring and perhaps not rewarding enough, so after a bit of a discussion on the official discord server, some other players and I came up with a suggestion for the fortress raids:
Cursed Fortress - A raid that is more difficult than the normal raids. Perhaps skeletons could have more health, deal more damage and possibly spawn in larger numbers or come in more waves than normal raids. Another suggestion for it was that the skeletons on the fort could fire cursed cannonballs. The reward for this kind of raid should also be higher than normal raids, of course. I thought this increased difficulty raid could be marked with a red skull cloud or something to easily tell them apart from normal raids.
