Latley I've been playing with what was the only option I could find close to my desired playstyle rn, /worldconfig creatureHostility passive, which undesirably makes all hostile animals passive as well. So I'm thrilled just a few days later your mod comes out with just what I wanted! Thanks :)

Would it be possible to make an option for them to become hostile based off range? (i.e. If you get too close they will aggro.)

TwelveWishes I think if you rename the file so that it's higher on the modlist, it should load first and take priority. Don't quote me on that though! >_>

Just letting you know that Combat Overhaul seems to modify the Bowtorns and so they keep their aggression - but as the people who install Combat Overhaul are presumably looking for a fight, not really a problem.

 All 3 creatures are affected no matter where they are.  TwelveWishes

You mention surface temporal creatures, am I to asume that those found in caves or of a higher level still aggro on the player?

Primelock They are idle during Temporal storms as well. They will only aggro if you attack them in general. I will see if I can get a config added at some point

Will they stay idle during Temporal storms? I think it's logical that they will aggro when there is a Temporal storm (configurable?), like how minecraft's spiders become aggressive in caves or darkness but neutral at day.

Peridot That's what I wanted! I hate being swarmed out of nowhere all the time, but they are brain dead with passive being enabled! 

Oh I appreciate the idea of this, like the surface variants have just enough brain left to be mindlessly wandering insead of fully aggressive beasts. Cool!
