Avoidance

If you would like to avoid monsters spawning near a certain position you can add avoidance like:

Monster AwesomeWildDog
RespawnInterval 60
GroupCount 3

Anchored 640 640
Avoid 300 300 100.0
Avoid 500 500 100.0
Count 100
Range 12 22

This will avoid monsters spawning near 300, 300 and near 500, 500 in a radius of 100 units.
