Causes something to desend or lower itself
- "With a whip-like movement, Crabbe pointed his wand at the fifty-foot mountain of old furniture, of broken trunks, of old books and robes and unidentifiable junk and shouted, "Descendo!" The wall began to totter, then crumbled into the aisle next door where Ron stood."
- —Crabbe tries to kill Ron with this spell.[src]
Descendo is a spell that likely causes any targeted object to move downwards.
Descendo is Latin for "I descend".
