This potion is made by using the Spider in the cauldron. Adding multiple spiders to the cauldron might give you more warts than usual.
Consuming this potion will make you grow big ugly warts all over your face & head. It doesn’t have any effects & won’t kill you. It’s mostly for fun & vanity.
As usual you can combine this potion with other potions to make hundreds of gross & warty concoctions.
This Potion is spell number #9 in the potions book.
