This mod changes the behaviour of bowtorns that spawn during temporal storms so that they retreat at the end of the storm the same way that drifters and shivers do.

NOTE: Any corrupt or nightmare variants that spawn during a storm will not retreat (changed in v1.1.0, see below). This also mirrors the behaviour of drifters and shivers.

ALSO NOTE: Bowtorns that spawn via any mechanism other than temporal storms (rifts, ruins, story locations) will not exhibit this retreating behaviour.

Why make this mod?

The primary intention of this mod is to eliminate the scenarios where a temporal storm spawns as many as a few dozen bowtorns that linger indefinitely after the storm has finished.

I didn't make this mod because I find the vanilla gameplay too hard; there are numerous effective strategies for dealing with groups of lingering bowtorns.  I made this mod because I find the current bowtorn "lingering" behaviour offends my aesthetic sensibilities.  One of the unspoken rules of the eldritch horror genre is that the horrors are creatures of the dark while the heroes are emissaries of the light.  Daylight is our greatest defence, and the rising of the sun is always our greatest source of hope. I feel that allowing bowtorns to linger on after a storm has passed and ignore the presence of full daylight cheapens the experience. It quite literally shines too much light on them. I'm a fan of the scene in James Cameron's Aliens where the little girl, Newt, tells Ellen Ripley "They mostly come at night... mostly."

I have play tested this mod, but not extensively.  If you encounter any unexpected behaviour please let me know!

Update: version 1.1.0

-Fixed an issue where two conflicting ai tasks would make a bowtorn continuously "ping pong" between retreating and approaching.

-Changed the ai task priorities to ensure that retreating bowtorns will still melee attack any player that comes into range.

-Gave all bowtorn variants a very small chance to retreat in full sun, to fix a situation where you have a pack of corrupt and stronger bowtorns waiting indefinitely outside your door.  All bowtorns should now wander off and despawn in approximately 2 game hours (so if the sun rises at 6:00am then they should be mostly gone by 8:00am or so).

For a slightly spicier temporal storm experience, try pairing this mod with Zippy's Fearless Foes.
