Previously as a private build a few friends and I build something we call a Murder Hole. The Thread about it can be found here: http://empireminecraft.com/threads/mob-chute-murder-hole.36112/ Its function is that of a Kill By Hand grinder and it is mostly for the purpose of getting Heads and Sulfer, but it can also be used to get other drops. If anybody happens to take an interest in having something like this as a public build Then I would like to start it up. Let me know your thoughts
I would definitely use this if it were apart of the smp8 utility network. My suggestion is building it out by Pigmentus and (FE-II), i think out by this area it would make a great addition.
It would need as much area as Sushi Drop, or more, and it couldn't overlap an area because it needs to be free of spawns for mobs other than the spawning pads. That being said.. That is a pretty plausible place for it to go. I'll scope it out.
