Mountain-moving spell

This charm (incantation unknown) breaks a mountain out of the ground, and drops it onto a target. Its incantation is quite long and complex.

In 1379, a wizard, who was the third semi-finalist to partake in an international duelling contest on Dartmoor, was planning to use this spell to drop a mountain onto the head of his opponent, Elizabeth Smudgling. Smudgling, however, muttered the shorter incantation of the Disarming Charm, outpacing the other wizard before he could complete the sesquipedelian incantation.
