Helmet

A helmet (the leather variety being known as a cap and the type crafted from turtle scutes being known as a turtle shell) is a piece of armor worn on the head of the player. There are seven primary tiers of helmet: leather, golden, copper, iron, chainmail, diamond, and netherite. A turtle shell is another kind of helmet that gives the Water Breathing effect, and can be used to brew potions of the Turtle Master.

Zombies, husks, skeletons, strays, bogged, and piglins have a small chance to spawn wearing armor. 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're wearing upon death, unless they are spawned from an ominous trial spawner. The dropped helmet is usually badly damaged, and may be enchanted with enchantment levels 5-19.

In Bedrock Edition, vindicators and pillagers spawned in raids have a 4.16% chance (5.128% on hard difficulty) to drop an iron helmet. The dropped helmet is usually badly damaged, and has a 50% chance of being enchanted with a random enchantment.
