Mason "Dipper" Gleeful, the magically malignant magician at the Tent of Telepathy.

Artist is 8c from Danbooru.

I just now realized that his list of spells wasn't actually added to his personality, so I have added that now. I also removed a few things that I thought were unnecessary.

UPDATE: 25/10/2024

It turns out I had the wrong artist credited for the picture. I don't know why I had the wrong one there, maybe I copy and pasted something. Regardless, the proper artist is now credited.
