This guide will let you know how to get the Robux Ingredient in Roblox Wacky Wizards.
First, you will need to complete the live event that happens once every hour.
Once you finish it, pick up one of the balls that it drops and take it to the cave with the wizard.
When you do it for the first time, it will give you Robux and a random item if you are doing it for the second time.
Once you have done that, you will have the Robux Ingredient.
