A die with 100 sides.
The D100 re-rolls all of your current items, all of the collectibles in the room, and all of the pickups in the room when activated.
The reason this is being added is due to the glitch this can cause. if you do a basement run with eden and have enough items and use this you become a glitch leviathan with tripleshot (not the item but effect) and dead cat. (MissingNo. & D4 can do this as well). This makes an otherwise invulnerable Isaac become weak.
