Okay so I playing in a dnd game as Mia the Aacockra Eldrich Knight and in the game we recently to new playing one of them being wild sorcerer meaning that when he casts a spell there's a chance he'll magic surge and something extremely random can happen instead.

Like in this drawning is a hypothetical situation where the wild mage casted Enlarge/reduce (actually dnd spell) on Mia and magic surges causing her to end being bigger than expected. Well at least this happened to an ally
