This emoji goes beyond just a mage; it can also be used metaphorically to describe a 'master' or 'sage' in a certain field. You can send it to a friend who came up with a brilliant solution to praise them.

In Western fantasy, mages often play the role of wise advisors. This emoji captures that wise image, so you can use it wittily when someone solves a difficult problem as if by magic or shows incredible wisdom.
