I really like this mod, and I like how configurable it is. I do have one problem with it, though. The ruins structure, the one that has the staff pieces for the boss fight? It's way too rare. There can be 5000+ blocks between two ruins, and they're not big structures. A player could easily miss them. And since there's 4+ types, a player would have to cover tens of thousands of blocks looking for the three staff pieces they need. I think if there was only 1000 blocks between ruins it would be more reasonable. And maybe make crypts more rare. They're very large structures and they seem to be everywhere.
