Effects while holding an item

Updated: 30 October 2026

1. Feather jump (Java 1.20.5+)

Put this in a repeating, always active command block:

/execute as @a if items entity @s weapon.mainhand minecraft:feather run effect give @s minecraft:jump_boost 1 2 true

The one-second duration means the effect ends as soon as the feather is put away.

2. Other slots

/execute as @a if items entity @s armor.feet minecraft:golden_boots run effect give @s minecraft:speed 1 1 true

3. Only a special item

/give @s minecraft:blaze_rod[custom_name="Fire Wand",custom_data={fire_wand:1b}]

/execute as @a if items entity @s weapon.mainhand minecraft:blaze_rod[custom_data~{fire_wand:1b}] at @s run particle minecraft:flame ~ ~1 ~ 0.3 0.5 0.3 0 5

The ~ in custom_data~{...} means a partial match: the item only needs to contain fire_wand:1b, so a renamed or enchanted wand still works. A plain blaze rod without the tag is ignored. See custom items and the particle command.

4. Bedrock

/effect @a[hasitem={item=feather,location=slot.weapon.mainhand}] jump_boost 1 2 true

Leave out location to match the item anywhere in the inventory.

Troubleshooting

• if items error: needs Java 1.20.5 or later.
• Effect lingers: keep the duration at one or two seconds.
• Special item ignored: the custom_data in /give and the check must match.
