Spawn rates iteration

Hi. this is something not essential for now. But could be interesting for the future:

Right now, if I’m not wrong, if you set a spawn rate, its a plain % that is considered en each single message. So, maybe you just faced a group of goblins, the chances to face another group again are the same always so it can happen that if the % is high, you keep geting encounters in kind of a loop.

I think it would be interesting for us worldbuilders to be able to set something like a variable encounter rate or two diferent % (spawn and respawn). For example, you set the % rate of the spawn high, at 15 or 20. That way, when the party enters the area, chances are high that they will face some encounter. But after defeating the first wave, maybe you want the chances to drop to 5-10.

Or for bosses/high dangers.
