Monster spawns can be annoying especially the tree dudes or the worms found all over the world. What if we had the chance for even for a bit prevent them spawning at all? The idea is that, if an area is hunted down of ALL monsters (AKA an area has been pacified) no more monsters will spawn for a certain amount of time. This is allow a kind of class “Monster Hunters” imagine having to not deal with any nasty worms for a while and just get some mining done.
Monsters will respond constantly if there are monsters alive in the area.
If they are all dead then the spawning ceases for a good chunk of time (hour or so).
Maybe people who do this can get post it boards that when completed (kill (x) number of enemy) give them stuff
