TRAZLANDERS SPAWNER FILTER NEEDED ! ! !

You need to put the Coordinates (for where people would stand to access the Mystery box) into the two command blocks in the back that have signs that say "PUT COORDS IN HERE", put them where it says 'x=--,y=--z=--'.

I designed a Mystery Box that actually has different drop chances and it is fairly small compared to the original.
You must run TrazLanders Spawner Filter on the whole schematic after you import it and put it where you want it.
Do NOT move it after you run the filter or it won't work.

If you want to add to the Mystery Box just add another chest with the item in it and place a sign on top of it with the same exact words as the others.(This must be done before running the filter). Depending on how rare you want the item just add as many chest as needed. Your Chest / Total Chest . Ex. The Diamond Sword is default 4/100 chance.

Update: More compact and can now be turned on and off, It has a teddy bear feature but it turns it off after you get an Item, so its a little more friendly. The teddy bear is a 10% chance.

(Mystery Box Switcher NOT included, you will have to build it yourself, Sorry :( )
