Minecraft wiki entry for Drowned_farming, associated text: The legs of the mobs are exposed to you. With your cheap weapon, or even bare hands, whack at the legs of a drowned. Four hits with a stone sword can kill it. Experience orbs float toward you, and the drowned's possessions drop into the hoppers and end up in the chest (or if you didn't use hoppers, the drops come to you if you get close enough). Eventually nautilus shells‌[Bedrock Edition only], as well as copper ingots, armor (leather, gold, and chainmail, often enchanted) appear in the collection chest along with rotten flesh and miscellaneous other items.
