Tainted Blood Pendant

The Tainted Blood Pendant provides an infinite brew at a mana cost. Firstly, look in the Lexica Botania for the recipe. It is Minecraftian knowledge. Then, use it in place of a vial/flask/incense stick in the Botanical Brewery to add a brew. Remember to point a mana spreader at the brewery, or it will sit there. After a long wait, it's brewed, put it on as any other Baubles amulet. Remember to have mana tablets/bands in your inventory/band slot. I'd also suggest aura band.
