Do monsters despawn?

[Kein]

Well, they do stay

No, as far as they lose you they WILL disappear if you are far enough from them. You don't need to go through loading door. That's how the script works. That's the rule.

In Chancel, tho, those 3 monsters triggered by capture script never will lose you while you are on the same level as they are. The only way to make them disappear is to drop them down, thru the floor, as my 1st B/T gallery video shows.
