Mob Spawns, is there order or chaos?

So basically, I wonder if the mobs come at random, or based off of net worth, and I mean the TYPE of mobs.

For instance, I can handle the stonelings fair enough on Hard Mode. (I only play RC on Hard atm)

It’s when the larger ones, or giant wolves, or kobolds come that I get annihilated.

So I just wonder if there’s some way I can sort of control what comes until I’m more prepared.

idk about mob type, but mob spawning locations are annoying to deal with

I don’t recall in detail, but some of them are based on net worth and such, yes.
If you want to find the exact details to what triggers them (or denies them from triggering all together), you can look at the campaigns and their respective encounters within /data/gm/campaigns.
