thx for the advice, i have no difficulty with the mobs, it's just there is too much coming on me anytimes, can't farm, can't build, without havin to fight everytime

maybe it's because my base is very close to black forest :/

That tells me you've not put up defenses like most do to make most of those things a non issue.

Trenches AND high ground raised walls are the easiest methods for this as most mobs are vertically challenged.

Later when you kill later game bosses you'll start to encounter events with flying mobs too so plan defenses for the future accordingly into your base construction considerations.

Being close to 1 biome will of course ensure that you encounter mobs from that biome but EVents are actually based on which tier boss you've previously killed. When you kill Eikthyr, you then trigger getting black forest biome events that can potentially spawn to intentionally attack you.

Events can thus happen in different biomes from the one the mobs are usually seen in. Think on it like the next boss is sending denizens to prevent you from killing em.
