Bottle of souls

A new potion, the potion can be called anything but I came up with the name the bottle of souls. You can make this potion by combining a splash potion and a totem of undying(the ingredients can be changed). You splash it down then vexes will come out they will fly around and kill any mobs they can find but not you. The vexes will eventually despawn after five minutes.(anything in here can be changed i don’t care)
