Potion Combiner [Potion Blending Combiner] Mod 1.20.1–1.21.1

Potion Combiner adds a new table capable of mixing up to three potions into a single bottle, combining and unifying all their effects to create much more powerful concoctions.

Once in place, the table will react visually to the ingredients: its colour will change depending on the potion you add, indicating which effects you are about to merge.
