How do I make a custom potion with Minecraft addons?
I have seen others do it (at MCPEDL, which is a site that you can post addons, resource packs, and maps).
I don't want to make a "potion" crafted at a crafting table, which isn't really a potion, and is counted as a food.
This is not similar to this question because that requires command blocks, I would like to use add-ons/behavior packs.
