Cauldrons and potions
Potion request-Felix felicis. Please. New ingredients to find and grow. Let it triple all XP awards. And/or it would help you find the elusive foundables from registry pages. And it should have a long brew time. 24 to 30 hours. Last for 30 minutes. It could also be given as a reward after brewing like 5000+ potions, and at very high level ups.
And let us buy an extra cauldron after level 30 or 40. Renting is ok but I would spent real money for a second cauldron.
