I have a straight path going into a slope/mountain that is at about a 45 angle. The distance from the front is almost identical to the depth.
My idea is to make a series of easy to destroy frame bars with camp fires between them. Ranged Damage, plus fire, and easy clean up to exit.
At which point will they choose to dig down vs, run through the front?
Is there a maximum distance between you and the entrance, that they will just spawn directly above and dig down?
If anyone has some metrics or a video to point me to that would be much appreciated.
