Explorer class
Finding bosses right now can be a hassle with all the ressourcegathering and so on, I think this should be tied in with exploration.
Cant we also go out and find hints about the boss location in the wilderness? If you cant figure it out with that go craft a scanner like it works right now. Some bosses roam and are harder to miss. The slimes make thumping noises, so just listen. Why not expand this?
Why not add some detective work! They could make this a new class to level up > The Explorer! Make it reveal more territory around the player with the use of skills and mark hints to bosses, waypoints when close enough and other structures with higher level.
Someone else also wrote a suggestion for rare monsters or stronger variants, maybe connect the explorer to something like that as well?
