How Held Items Affect Stats
Held items can dramatically change a Pokemon's effectiveness in battle. Some items directly modify stats, while others boost move power or provide utility. Understanding item interactions is essential for competitive team building.
Stat-Boosting Items
| Item | Effect | Restriction |
|---|---|---|
| Choice Band | Attack ×1.5 | Locks to first move |
| Choice Specs | Sp. Atk ×1.5 | Locks to first move |
| Choice Scarf | Speed ×1.5 | Locks to first move |
| Assault Vest | Sp. Def ×1.5 | No status moves |
| Eviolite | Def & Sp. Def ×1.5 | Unevolved Pokemon only |
| Thick Club | Attack ×2 | Cubone / Marowak only |
| Light Ball | Attack & Sp. Atk ×2 | Pikachu only |
| Quick Powder | Speed ×2 | Ditto only |
| Metal Powder | Def & Sp. Def ×1.5 | Ditto only |
| Soul Dew | Sp. Atk & Sp. Def ×1.5 | Latias / Latios only |

These items don't change the displayed stat but boost move power:
- Life Orb: +30% move power, costs 10% HP per attack
- Expert Belt: +20% power on super-effective moves
- Type-boosting items (Black Belt, Charcoal, etc.): +20% to matching type moves
- Plates (Flame Plate, Splash Plate, etc.): +20% to matching type, changes Arceus form

Item Strategy Guide
When to Use Choice Items
Choice items (Band, Specs, Scarf) provide a massive 50% boost to one stat, making them the strongest stat-boosting items. However, they lock the user into the first move used. They're best on:
- Pokemon that only need one or two moves to do their job
- Late-game cleaners that can sweep with a single move
- Scarf users that need the Speed boost to outspeed threats
Eviolite: The Budget Wall
Eviolite gives a 50% boost to both Defense and Special Defense, but only works on Pokemon that haven't fully evolved. This makes unevolved Pokemon surprisingly bulky:
- Chansey with Eviolite is even tankier than Blissey on the special side
- Dusclops with Eviolite rivals Dusknoir in bulk
- Porygon2 with Eviolite out-tanks Porygon-Z
Species-Specific Items
Some items only work on specific Pokemon but provide enormous boosts:
- Light Ball (Pikachu): Doubles both Attack and Sp. Atk, making Pikachu hit like Raichu
- Thick Club (Marowak): Doubles Attack, making Marowak one of the hardest physical hitters
- Soul Dew (Latias/Latios): 50% boost to both special stats
Item-Ability Interactions
Item effects stack multiplicatively with ability modifiers. Understanding these interactions is key to maximizing damage output:
| Ability | Item | Combined Effect |
|---|---|---|
| Huge Power (x2 Atk) | Choice Band (x1.5 Atk) | x3.0 Attack total |
| Pure Power (x2 Atk) | Life Orb (x1.3 dmg) | x2.6 Attack + 30% damage |
| Guts (x1.5 when status) | Toxic Orb | x1.5 Attack + immune to other statuses |
| Quick Feet (x1.5 Spe when status) | Toxic Orb | x1.5 Speed + status immunity |
| Adaptability (x2 STAB) | Choice Specs (x1.5 SpA) | x3.0 Sp. Atk + x2 STAB |
These calculations follow the item modifier logic from the smogon/damage-calc open-source project, which is the same engine used by the official Pokemon Showdown damage calculator.
Frequently Asked Questions
How do Choice items affect stats?
Choice Band multiplies Attack by 1.5, Choice Specs multiplies Special Attack by 1.5, and Choice Scarf multiplies Speed by 1.5. The trade-off is that the Pokemon is locked into the first move it uses. These are the strongest stat-boosting items in the game, providing a 50% boost.
Does Eviolite work on fully evolved Pokemon?
No. Eviolite only works on Pokemon that can still evolve. It multiplies both Defense and Special Defense by 1.5. This makes unevolved Pokemon like Chansey, Porygon2, and Dusclops surprisingly bulky — sometimes outperforming their evolved forms.
What is the strongest item for Pikachu?
Light Ball is exclusive to Pikachu and doubles both Attack and Special Attack (x2.0 multiplier). This makes Pikachu hit as hard as many fully evolved Pokemon. Without Light Ball, Pikachu's base stats are too low for competitive play.
How does Thick Club work?
Thick Club is exclusive to Cubone and Marowak. It doubles their Attack stat (x2.0 multiplier). Combined with Marowak's base 80 Attack, this gives an effective Attack of 160+ — comparable to top-tier physical attackers. Alolan Marowak also benefits from Thick Club.
Do Mega Stones change base stats?
Yes. When a Pokemon Mega Evolves, its base stats are completely replaced with the Mega Evolution's base stats. For example, regular Garchomp has 108/130/95/120/85/102, but Mega Garchomp has 108/170/115/120/95/92. The stat change happens before IVs, EVs, and natures are applied.
How do items interact with abilities?
Item effects stack multiplicatively with ability modifiers. For example, a Pokemon with Huge Power (x2 Attack) holding a Choice Band (x1.5 Attack) gets a total x3 Attack multiplier. However, some abilities like Klutz prevent item use entirely, and the move Knock Off removes held items.
