Minecraft wiki entry for Difficulty, associated text: Hostile mobs deal more damage than on Normal difficulty, and in some cases drop higher-value items when killed. The hunger bar can deplete, not only damaging but also killing the player if it drains completely. Zombies can break through wooden doors and can spawn reinforcements when attacked. Spiders can spawn with a beneficial status effect (speed, strength, regeneration, and invisibility), with these effects having a nearly infinite duration in Java Edition. Villagers killed by zombies always turn into zombie villagers. Pillagers spawn near the player, with their attacks dealing 4 damage. In Bedrock Edition, if the world type is infinite, they deal 5 damage.
