Double effect potions & witchery stands.

Double effect potions can be obtained by:

-Killing witches.

-in stuctures, such as:strong holds, witch huts...

-crafting them up youself in the witchery stand.

Wtchery stands (I didnt know how to call them, so you can call them however you want)

Crafting recepie:

Blaze_rod [   nether_star   [ Blaze_rod

Blaze_rod ] brewing_stand] Blaze_rod 

Obsidian   [     diamond      [ Obsidian 

(exactly as placed)

This new item would work exactly as a brewing stand but when a regular potion in placed in  the ingredient tile and other potions with a different effect in the "potion" tiles so at the end of the process they will have the same effect.

Also its faster. 

*(& maybe, just maybe act as a work station to a "magician villager")
