Black Belts can only be obtained from the elderly man living in a house on Route 221. Once per day he will ask you to show him a Pokémon of a random level, and Black Belts are one of three items he will reward you with if you do.
As for the item’s effects:
The Black Belt is a Hold Item that boosts the power of Fighting-type moves by 20%.
Black Belt Location (Step-by-Step)
You can get Black Belts from the elderly man that’s inside the blue-roofed house on Route 221, just to the west of Pal Park.
Once per day the man will ask if you can show him a Pokémon of a random level; if you have a Pokémon of this level in your party, the man will award you one of three potential items that follow a specific pattern – and one of these items is a Black Belt.
The quickest way of reaching the elderly man’s house is by Flying to Pal Park and heading west on the path to the left of the signpost.
Head west down the long linear path here, passing the Berry patch to your south.
Then turn north as soon as you can & take the right-hand path going up through the grass.
Keep following this path until the end, then enter the house with the blue roof.
Speak to the elderly man inside and he will request that you show him a Pokémon of a particular level. The specific level he asks for is random and changes daily.
If you have a Pokémon of this level in your party, he will become ecstatic and award you an item.
Here’s the order of items you’ll get:
- The first time you show him a Pokémon he will give you a Black Belt
- The second time he will give you an Expert Belt
- The third time he will give you a Focus Sash
This can be repeated infinitely, and the cycle starts over with another Black Belt after you receive all three items for the first time.
Black Belt Details and Uses
The Black Belt is a Hold Item that boosts the power of Fighting-type moves by 20%, giving it the same primary effect as the Fist Plate.
This is a good item for Fighting-type Pokémon to hold to further stretch their STAB damage. And unlike items such as the Wise Glasses and the Muscle Band, the Black Belt boosts both physical and special moves.
Granted, there are other items that offer bigger, broader boosts in power – but usually they come with some caveats.
For example: the Life Orb boosts all damaging attacks by 30%, but siphons 10% of the holder’s maximum HP every time one is used.
Are Black Belts Worth Using?
The Black Belt’s single-type boost pales in comparison to those offered by other items, but it also has no drawbacks to complicate battles with.
If you have a Fighting-type on your team who needs a simple but effective held item, this is a good one.
