The Exstimulo Potion is a potion that enhances the power of a single spell cast by the drinker. The power of the spell depends on the quality of the potion. The Strong Exstimulo Potion and Potent Exstimulo Potion are significantly stronger variants of this potion.
This potion was brewed and used heavily by volunteer wizards and witches employed by the Statute of Secrecy Task Force, to help address the issue of the Calamity in the 2010s. It allowed the drinker to boost the magical power of their spell casts, and was particularly practical when dealing with Confoundables and engaging in Wizarding challenges in Fortresses.
