This is another simple mod with powerful customization features that allows you to use up to 9 different potions and combine them into one. You can mix at least 2, or make full use of 9 spaces to mix. It has many combinations and every effect can be added, whether they are beneficial or negative.
When you hover over a combined potion, you'll see all of its effects, with their duration indicated.
What's more useful about this mod is the ability to combine arrows. Now you can make super powerful arrows.
