How to make a shield in Minecraft, and the 0.25 s before it blocks
Six planks and one iron ingot make a shield in 26.3. What it blocks, what passes through it, why an axe disables it for 5 seconds, and how to add a banner.
The shield recipe is one iron ingot and six planks, read from data/minecraft/recipe/shield.json in Java 26.3:
W o W W = #minecraft:wooden_tool_materials (any planks)
W W W o = minecraft:iron_ingot
W → 1 × minecraft:shieldThe planks are a tag, so the six do not have to match: oak, spruce, birch, jungle, acacia, dark oak, pale oak, mangrove, cherry, bamboo, crimson, warped and poplar planks all count, mixed or not. Some armorers sell one too: at journeyman level they draw two trades from a pool of five, and a shield for 5 emeralds is one of the five.
How blocking works
Hold the use button with the shield in either hand. Everything below comes from the shield's blocks_attacks component and the code that reads it:
| rule | value |
|---|---|
| delay after raising before it blocks | 0.25 s (5 ticks) |
| arc it protects | within 90° of where your head faces — the front half |
| damage blocked inside that arc | 100% |
| durability lost per block | none below 3 damage; otherwise 1 + the damage, rounded down |
| durability | 336 |
The delay is the part that catches people. A shield raised at the last instant does nothing for the first five ticks, so against a charging mob it has to come up early. And because the arc is measured from your head, turning to look at something beside you turns the shield with you.
The durability rule means small hits are free and big ones are expensive: a 10-damage hit costs 11 durability, so a fresh shield absorbs about thirty of them.
What a shield does not stop
Three things get past it regardless of where you face:
- Damage types tagged
#minecraft:bypasses_shield— 30 of them in 26.3, including falling, fire and lava, drowning, starving, magic and potions, lightning, cactus and berry bushes, and the Warden's sonic boom. - Arrows with Piercing. Any Piercing level at all and the arrow ignores the shield.
- An attack from behind you, outside the 90° arc.
Why an axe breaks your guard
When a mob or player hits your raised shield with an axe in its main hand, the shield is disabled for 5 seconds (100 ticks) — the axe's weapon component carries disable_blocking_for_seconds: 5, and swords carry nothing. A Warden's melee attack disables it for 5 seconds too. Disabling only happens on a melee hit from a living attacker; arrows never disable a shield.
Putting a banner on it
Place a shield and any banner together in a crafting grid. The shield takes the banner's base colour and its patterns, and the banner is used up. Two rules from the decoration recipe:
- the shield must not already carry patterns — you cannot stack a second design on top
- the result copies the banner exactly, so design the banner first
A decorated shield can still be repaired and enchanted like a plain one.
Repairing and enchanting
A shield repairs with planks in an anvil (the same #minecraft:wooden_tool_materials tag as the recipe), or by combining two damaged shields. Only three enchantments apply to it: Unbreaking, Mending and Curse of Vanishing.
The design is the part people spend longest on. The Banner Designer builds a banner from a base colour and up to six layers with a live preview, and gives the /give command for it — craft that banner with your shield and the design goes onto the shield as-is.
