Hello here’s a suggestion.
Besides the corrupted portals, around the map (or instead of them so you don’t have any problem coding the placement) you can randomly add variety of stuff.
Let’s say:
- a mini boss wandering around
- a special chest guarded by many elite mobs
- some big group of minerals ( or a very big one )
- a special npc that gives stuff
Just by adding some of those the world can feel more alive
