This potion is made by using Pet Tags + Fairy in the cauldron. This potion can’t be stacked to increase its effects.
Drinking the Magical Potion will spawn a pet unicorn next to you. The pet unicorn will follow you around the map while you play around with your potions.
You can pick the unicorn up in your hands or pet him.
Other than looking cute, pets don’t really do much for now.
This Potion is spell number #124 in the potions book.
