Fire Protection

Fire Protection is an uncommon armor enchantment in Minecraft 1.21. Fire Protection specialises against heat, cutting fire and lava damage and also shortening how long you stay alight once you catch fire.

Its opening level already delivers a noticeable boost — 8% fire damage reduction, -15% burn time — and it climbs from there to a maximum of level 4 (IV) on your leggings.

Fire Protection tops out at level 4, shown as IV on the leggings, and the gap between the levels is where the enchantment's character really lives.

Four levels, each removing 8% of fire damage, reaching 32% on a single piece at level IV. On top of the damage cut, each level trims your burning time by about 15%, so a full set lets you escape flames and lava far more quickly than bare armor.

Fire Protection can be placed on helmet, chestplate, leggings and boots, giving you a handful of choices for where it does the most good depending on how you play.

Fire Protection cannot share an item with Protection, Blast Protection and Projectile Protection. All of these sit in the same mutually-exclusive group as Fire Protection, so an item can wear only one of them at once and you choose which playstyle to commit to.

Fire Protection can be rolled directly at an enchanting table, where reaching its top level of IV on a leggings generally wants a fully bookshelf-powered table at roughly level 8. If the table is not cooperating, the Fire Protection book also comes from loot chest and villager trading, ready to apply on an anvil.

Its selection weight of 5 makes Fire Protection an uncommon roll: it appears with middling frequency when enchanting a leggings — common enough to plan around, but not guaranteed on any given roll.
