By installing this mod on your server (or on your client when playing singleplayer), the myth of timing your clicks to obtain the items you want actually becomes a reality!

This mod adds 2 new gamerules, that modify the vault drop behaviour, those are:
/gamerule modifyNonOminousVaults
This gamerule determines whether the non-ominous vault variant should be modified so that the mod's logic is applied. By default, it is set to true.
/gamerule vaultsShouldAlsoDropDefaultLoot
This gamerule determines whether the vaults should also drop the default loot in addition to the modified loot. By default, it is set to true. In mod version 1.0 this gamerule, doesn't work as intended, so please update to/download the latest version of the mod.
