Ultimate Randomizer Multiplier

Chaos Drop completely randomizes every drop in the game — breaking blocks and killing mobs no longer gives their normal loot. Instead, each source is permanently assigned a random result: either a random item drop or a random mob spawn, in a random quantity. Half of all assignments drop items, the other half spawn mobs — so yes, breaking dirt might spawn 12 Wardens, and killing a Warden might drop a single potato.
The assignments are saved to your world, so they stay consistent until you decide to reset them. No tool requirement either — every block drops something regardless of what you break it with.

Commands

/chaosreset — Wipes and fully re-randomizes all drop assignments. (OP only)
/chaosmultiplier — Sets the maximum possible quantity for drops and spawns. For example, setting it to 50 means any given drop could be anywhere from 1 to 50. Run /chaosreset after to apply the new range. (OP only)
/chaosinfo — Shows your current multiplier setting. (Everyone)
