Did you see this new one? It seems to have gotten some good comments so far. It is an area script rather than a trash-fairy type system and it also de-spawns encounter monsters if no players are present. I will be testing this in my arenas in the coming weeks, I'll let you know how it goes if you want. [img]smile.gif[/img]

I have tried a few others from the vault and did not like them. They either did not work, or did a half-ass job.
