Mayhem spawner was scripted by Haazen (primary idea came from Botnick) in July 2005.
It used in many cases:

1. There are several places that some unexpected critters may show up. There may be just 1 unexpected critter or there may be 20. Just depends on what is set.

2. The Mad Crafter has been added to these spawners. Mad Crafter spawns at many, many different spots. You will have to find where she is. But be assured that she is spawned somewhere in the world all the time. Good luck on your search.

3. The stealable rares have been added to these spawners.

4. Other non-stealable rares have been added to these spawners. There are banners, raw furniture and some other items for house deco that have not been available before now.

5. They are used for event at entrances to dungeon - event known as "Creatures escape from dungeon"

Some info about these spawners: Mayhem spawners can be single or are grouped together by an array number. There is no limit to how many Mayhem spawners can be in any group. Only one spawner in any group is active at a time. These spawners can be set to spawn one or a number of critters/items. After the critter has been killed or the item has been taken, the spawner shuts off and one of the others in the set turns on.

Example: spawner 1, spawner 2, spawner 3. All 3 have Mad Crafter on it. Spawner 1 is active and the Mad Crafter is there. Only after the Mad Crafter is killed at spawner 1, then the Mad Crafter will spawn at spawner 2, spawner 3 or maybe even at spawner 1 again. But only one of the set is active at a time.
