Magic

Magic is an option in Infiltrating the Airship during the Final Fantasy-style fight between Henry Stickmin and the Right Hand Man.

If the player chooses Magic, Henry calls for magic for one turn and the Right Hand Man casts Reflect on himself. Then Henry casts fire on the Right Hand Man, which is reflected back at Henry, dealing 812 damage and killing him. This results in a fail.

Gee that... BackFIREd.

10/10 jokes here folks.
