"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, or in other words causes something to descend or lower itself. Therefore, it could be used as a specific counter-charm for spells like the Levitation Charm and the Flying Charm. Descendo itself could be countered with the General Counter-Spell, like any other charm and minor Dark spell.

Behind the scenes

In the Nintendo DS version of the video game adaptation of Harry Potter and the Deathly Hallows: Part 2, players can lower floating objects by tapping on them with the stylus. This is possibly a use of Descendo, though it is never explicitly identified as a spell at all.
