okay then my world seed is really bad for iron because none of the close to the center swamps have crypts even tho the swamps are medium size and not that far from the center all the swamps have plains surrounding the swamps. Like this seed has the longest swamp I have ever seen and even that swamp is surrounded by plains. But that island is quite far.

Are the wraiths and overall swamp mobs a pain in the ass if you make a swamp base?

That does happen. On the server I play on the 2 closest swamps had 0 and 2 crypts and this is where Bonemass was. Completely surrounded by plains, far from shore, and a mountain that was unclimable on the safer side.
