Minecraft wiki entry for Wither, associated text: The wither always drops one Nether Star upon death. In Java Edition the dropped nether star takes ten minutes to despawn, though in Bedrock Edition the nether star never despawns. It cannot be destroyed by explosions, although it can be destroyed by a falling anvil,‌‌[Java Edition only] cactus, fire, or lava. The Looting enchantment does not increase this drop. A wither also drops 50 when killed by a player or a tamed wolf.
