Chainmail Helmet

A chainmail helmet[a] is an uncommon variant of helmet that cannot be crafted, and is only obtainable through other means such as trading. It is the fourth-highest tier of helmet, having the same armor points and durability as an iron helmet but with higher enchantability.

Zombies, husks, skeletons, strays, and bogged have a small chance to spawn wearing armor, which may include a chainmail helmet. There is a 8.5% chance (9.5% with Looting I, 10.5% with Looting II and 11.5% with Looting III) for the mob to drop the helmet they are wearing upon death unless they are spawned from an ominous trial spawner‌[Java Edition only]. The dropped helmet is usually badly damaged, and may be enchanted with enchantment levels 5-19.

Armorer villagers may give the players with the Hero of the Village effect a chainmail helmet.‌[Java Edition only]
