Which items take Thorns

Enchanting table

Chestplates, and books.

Not from the table

Helmets, leggings and boots: an anvil adds it, and some chest loot comes with it.

The table offers an enchantment only on its primary items; an anvil can add it to anything that can hold it. See every enchantment an item can hold in the max enchantments by item tool.

Conflicts

Nothing: Thorns combines with every other enchantment its item can hold.

Enchanting table odds

Chance that one offer in the bottom slot (level 30, 15 bookshelves) includes Thorns, on a diamond chestplate and on a book.

Power window per level

A table roll picks the highest level whose window contains the roll’s modified enchantment level. These are the registry’s min_cost and max_cost, not the level cost shown on the table.

Anvil cost

An anvil charges ×8 per level when Thorns comes from another item and ×4 per level when it comes from a book, so adding Thorns III from a book costs 12 levels before any prior-work penalty. Work out a full combine in the anvil cost calculator.

Command

Hold the item in your main hand and run this with cheats on. /enchant refuses an item that can’t hold Thorns and any level above III.

Thorns: common questions

What is the maximum level of Thorns?
Thorns goes up to level III (3).
Can you get Thorns from an enchanting table?
Yes, on chestplates, and on books. Helmets, leggings and boots can hold it too, but the table never offers it on them: it goes on at an anvil, from an enchanted book or another item that has it. Armour from ruined portal, bastion and shipwreck chests can also come with it already on.
What does Thorns conflict with?
Nothing: Thorns combines with every other enchantment its item can hold.
