Sage Shroom (Patreon)

It is no surprise that many wizards hoard this mysterious mushroom. Some even burn it as incense, believing its fumes grant greater insight into the wonders of the universe. Unsurprisingly, Apprentices have been banned from using it before their exams.

Magic mushroom - in the full sense of the word. I was hesitant to use 'mana potion' as I feel it becomes too video-gamey...instead of going for 'potion of power' as it is similar to the pearl of power, except a one-time use. Both the potion and the mushroom are nifty and simple things for adventurers to find!
