A mystical being offers you and only you a magical claw machine. The prizes inside are magical items found throughout fiction with the exception of any fanfic you have written.
You have a 65% of getting an item that will be beneficial to you and a 35% of getting an item that could cause some form of harm to you and possibly those around you.
The items range from being palm sized to the size of a breadbox.
To activate the claw machine for the first time, requires a drop of blood. Additional uses require two drops of blood.
Even if you get a genie's lamp or something else that grants wishes, you can't wish to undo the rules.
Do you take the offer?
