Witherbloom Brewer

You are able to make potent potions, unguents, tinctures, tisanes, powders, and the like. When you take this feat, you gain proficiency with herbalism kits if you don’t already have it, and you learn four Witherbloom Brew recipes of your choice that you don't already know from the Witherbloom Brews list. Additionally, you can use this feat to craft up to two Witherbloom Brews that you know the recipe for by using a herbalist kit and spending 10 minutes per brew during a long rest. You must have an appropriate container to store each brew in. Some brews are drinkable liquids and are best stored in a flask, wineskin, or bottle. Other brews are powders best stored in a pouch or a vial, or salves or oils best kept in a pot or jar. And so on.

Each brew retains its magical potency for 24 hours or until it is expended (whichever comes first). You can keep each brew for your own use or give it to someone else to use. You cannot use this feat to make another brew if you already have two unused brews in existence that you used this feat to make. Saving throws made to resist the brews created using this feat are made against a DC equal to 8 + double your proficiency bonus.

You can take this feat up to three times total, learning four additional Witherbloom Brew recipes you don't know and increasing the number of unused brews you can have in existence by two each time you take the feat.
