Hey @Jim1

Thanks for letting us know. Sending your feedback to our team so they can look into it.

I have actually found that they will stop shooting at a target if they run out of arrows during a purge. To improve the archers lethality, I have been equipping mine with poison arrows and hardened steel arrows. I have actually found that the purge will not move out of the gas cloud. As for the Orb throwers, do not give them orbs since they will damage your base and other thralls.
