Every hit in Pokemon Champions comes down to math. The damage formula takes your Pokemon’s Attack (or Special Attack), the defender’s Defense (or Special Defense), the move’s base power, and layers on multipliers for type effectiveness, STAB, held items, weather, and more. Knowing how those pieces fit together is what separates players who hope for a KO from players who know they have one.
The Core Damage Formula
Pokemon Champions uses a damage calculation structure inherited from mainline competitive Pokemon. The base calculation looks like this:
Damage = ((2 × Level / 5 + 2) × Power × Atk / Def) / 50 + 2
Then that base number is multiplied by each applicable modifier in sequence. At level 50 (the standard competitive format), the level portion simplifies, and the fight between Atk and Def — or Sp. Atk and Sp. Def — becomes the primary lever you control through EV investment, nature, and held items.
The exact coefficient values are based on the standard Pokemon formula. If a future Champions patch adjusts these, ChampsDex will update this article with the relevant patch version.
What this means in practice: a higher base power move deals more damage, but multipliers often matter more than base power. A 90-power STAB super-effective move hits harder than a 120-power neutral move with no modifiers.
Physical vs. Special Moves — Getting the Category Right
Every damaging move in Pokemon Champions belongs to one of two categories:
| Category | Uses Attacker’s Stat | Defended By |
|---|---|---|
| Physical | Attack | Defense |
| Special | Special Attack | Special Defense |
You can tell the category by the move’s icon in-game. This distinction is foundational. Investing EVs in Special Attack for a Pokemon that only has physical moves is a complete waste — and a mistake that new players make constantly.
Some Pokemon are mixed attackers (strong in both Attack and Special Attack), but most specialists lean hard into one side. Garchomp is a physical attacker. Gengar runs special. Check your move categories before finalizing any competitive build.
For a deeper breakdown of how EVs and IVs interact with these stats, see the EV and IV stats guide.
STAB — The 1.5x Bonus That Adds Up Fast
STAB stands for Same-Type Attack Bonus. When a Pokemon uses a move matching one of its own types, that move gets multiplied by 1.5x. This might sound modest, but it stacks with every other modifier.
A Fire-type Charizard using Flamethrower (a Fire-type move) gets STAB. That same Flamethrower hitting a Grass/Steel type gets STAB + double super-effective (4x) + potentially a held item boost — the damage climbs fast.
STAB is also why coverage moves sometimes underperform against expectations. A Charizard using a Dragon-type move doesn’t get STAB (unless it’s also Dragon-type), so even if Dragon hits neutral, its effective damage may be lower than a STAB Fire move hitting something that resists it.
Key rule: When choosing between two moves of similar power, almost always prefer the one that gets STAB. The 50% bonus compounds with everything else.
Type Effectiveness — The Multiplier That Wins Games
Type matchups are the most visible layer of damage calculation, and they follow the standard 18-type chart from mainline Pokemon. Here’s the breakdown:
| Effectiveness | Multiplier | Example |
|---|---|---|
| Super-effective | 2x | Water vs. Fire |
| Double super-effective | 4x | Ice vs. Flying/Dragon |
| Neutral | 1x | Normal vs. Normal |
| Not very effective | 0.5x | Fire vs. Water |
| Double resisted | 0.25x | Fire vs. Water/Rock |
| Immune | 0x | Normal vs. Ghost |
Stacking super-effective matchups is one of the fastest ways to swing damage in your favor. A 4x weakness is often a one-hit KO regardless of bulk — building teams with overlapping weaknesses is a critical mistake that the meta threats and counters guide covers in depth.
Type immunity is also worth respecting. Ground-type moves don’t touch Flying-types. Electric-type moves fail against Ground-types. These hard stops can completely shut down a coverage plan if you haven’t accounted for them.
Stat Stages — Boosts, Drops, and Burn
The damage formula uses the attacker’s and defender’s current effective stats, including any stage modifications from moves like Swords Dance, Nasty Plot, Intimidate, or Screech.
| Stage | Multiplier |
|---|---|
| +6 | 4x |
| +4 | 2.67x |
| +2 | 1.5x |
| 0 | 1x |
| -2 | 0.67x |
| -4 | 0.5x |
| -6 | 0.25x |
A single Swords Dance (+2 Attack stages) turns many physical attackers into one-shot threats. This is why speed control matters so much — getting a boost off requires surviving the setup turn. The speed tiers guide explains which Pokemon need speed investment to threaten setup safely.
Burn status cuts physical damage by half — effectively applying a -2 Attack penalty in the damage formula without showing as a stage change. This is why Will-O-Wisp is one of the most impactful status moves in competitive play. Burning a physical sweeper can make them functionally harmless.
See the full status moves guide for how other status conditions interact with the damage formula.
Held Items and Damage Multipliers
Held items are the most direct way to boost your damage output beyond stat investment. The most important categories (multipliers reflect mainline Pokemon mechanics — Champions may adjust specific values; confirm against current patch notes):
Multiplier items (stack with all other modifiers):
| Item | Effect | Notes |
|---|---|---|
| Choice Band | +1.5x Physical damage | Locks you to one move |
| Choice Specs | +1.5x Special damage | Locks you to one move |
| Life Orb | +1.3x all damage | User takes 10% HP recoil per hit |
| Type-boosting plates | +1.2x matching type | No drawback — lower multiplier |
Choice Band and Choice Specs are among the most discussed damage items in early Champions community reports, though the full item roster and competitive usage is still taking shape as the meta develops. The 1.5x bonus is massive, but the move-lock forces you to predict well. Clicking the wrong move into a resist or a switch can cost you the game.
Life Orb is more flexible (you can switch moves freely) but the recoil adds up. For Pokemon with diverse movepools or unpredictable roles, Life Orb is often the better choice.
For a comprehensive item breakdown, see the held items guide.
Critical Hits
Critical hits bypass the defender’s positive Defense or Special Defense boosts and deal 1.5x damage. They land at a base rate of approximately 1-in-24 under standard conditions.
Some moves and abilities raise the critical hit ratio — high-crit moves like Stone Edge or abilities like Super Luck increase the chance. A few builds are specifically designed around fishing for critical hits (particularly in situations where a critical hit is the only way to break through a defensive setup).
Competitively, you cannot rely on critical hits. Plan for the non-critical damage range. If your set up requires a critical hit to KO, it’s not a reliable win condition — it’s a coin flip.
Weather, Terrain, and Environmental Multipliers
Weather and terrain add another layer of multipliers on top of the base formula. These are build-around conditions, not passive bonuses.
Weather damage modifiers (standard Pokemon rules apply):
| Condition | Boosted | Weakened |
|---|---|---|
| Harsh Sun | Fire ×1.5 | Water ×0.5 |
| Heavy Rain | Water ×1.5 | Fire ×0.5 |
| Sandstorm | — | — |
| Snow | — | — |
Terrains (Electric, Grassy, Misty, Psychic) each boost specific move types for grounded Pokemon. Based on mainline Pokemon mechanics, terrain conditions add approximately a 1.3x multiplier to the relevant type for grounded Pokemon — the exact values in Champions may be adjusted by patch, so check current community resources for confirmed numbers.
Weather teams and terrain teams stack these multipliers deliberately. A Rain team pairing a water-type with Swift Swim is dealing boosted Water STAB damage while moving first — that’s STAB + Rain + potentially Choice Specs, all at once.
For team building around these conditions, check the weather teams guide.
Damage Ranges and the Random Roll
The damage formula doesn’t produce a single exact number — it produces a range. The game applies a random multiplier between 0.85 and 1.00 to the calculated damage value. This means the same move hitting the same target can deal slightly different amounts each time.
Competitive players talk about damage ranges as percentages of the target’s HP:
- Guaranteed OHKO: The minimum roll still KOs (85% roll or higher doesn’t matter)
- High roll OHKO: Only KOs on rolls above ~90%
- Two-hit KO range: The move reliably KOs in two hits, and the second doesn’t need a high roll if the first landed
Knowing your damage range is how you make decisions about whether to attack again or pivot. “I need a high roll to finish this” is different from “I’m guaranteed to KO here.” Damage calculators exist specifically to map these ranges for your set vs. common defensive benchmarks. This is an essential tool once you’re playing at higher ladder ranks.
Putting It Together — Reading a Damage Situation
When you’re in a battle and deciding whether to go for a KO, you’re quickly running through these layers:
- Which stat does my move use? (Physical or Special)
- Does this move get STAB?
- What’s the type matchup? (2x, 1x, 0.5x, 0x)
- Are there stat stage changes active? (Boosts, drops, burn)
- Does my held item apply? (Band, Specs, Life Orb)
- Is weather or terrain active?
- What’s the damage range? (Can I OHKO or do I need two hits?)
This chain is fast once internalized. Early on, STAB + type effectiveness covers most decisions. At higher ladder ranks, held item interactions and damage range precision start mattering more.
The beginner’s guide to Pokemon Champions covers the broader competitive fundamentals if damage calc is your first deep dive.
Common Mistakes to Avoid
Investing EVs in the wrong attacking stat. Physical moves don’t care about your Special Attack. Always check move categories before finalizing EVs.
Ignoring burn. Burning a physical attacker cuts their damage in half. If you’re running a physical sweeper, avoid getting burned — consider a Lum Berry or a Fire-type if you’re facing Wisp-users often.
Undervaluing STAB. An 80-power STAB move often outperforms a 100-power coverage move. Don’t chase coverage at the expense of STAB consistency.
Treating every 2x weakness like a 4x weakness. There’s a meaningful difference. A 2x hit may not OHKO a specially defensive Pokemon; a 4x hit almost certainly will. Knowing which weaknesses are exploitable vs. survivable changes your targeting decisions.
Over-relying on critical hits. If your damage calculation only works with a crit, you don’t have a reliable play. Adjust the set.
FAQ
What is the damage formula in Pokemon Champions? Pokemon Champions uses the same core formula as mainline competitive Pokemon: Damage = ((2 × Level / 5 + 2) × Power × Atk / Def) / 50 + 2, then multiplied by type effectiveness, STAB, and other modifiers. The exact coefficients may vary slightly pending official patch notes, but the structure is standard competitive Pokemon.
What does STAB mean in Pokemon Champions? STAB stands for Same-Type Attack Bonus. When a Pokemon uses a move that matches one of its own types, that move deals 1.5x damage. If a Pokemon has a form change or type-altering mechanic active, the effective type used for STAB may shift — always check the Pokemon’s active type when calculating.
How does type effectiveness work in Pokemon Champions? Type matchups follow the standard Pokemon type chart. Super-effective hits deal 2x damage; double super-effective (like an Ice move hitting a Flying/Dragon) deal 4x. Not-very-effective hits deal 0.5x, and immune types deal 0x. The full 18-type chart applies.
Does Attack or Special Attack matter more in Pokemon Champions? It depends on the move. Physical moves use the attacker’s Attack stat vs. the defender’s Defense stat. Special moves use Special Attack vs. Special Defense. Checking a move’s category (physical or special) before building EVs is critical — putting EVs in the wrong attacking stat is a common beginner mistake.
What are EVs and why do they affect damage? Effort Values (EVs) are hidden stat points you invest into a Pokemon’s stats. Putting 252 EVs into Attack or Special Attack significantly raises your damage output. The maximum is 252 in one stat, 510 total across all stats. Competitive builds almost always maximize their primary attacking stat.
How do held items affect damage in Pokemon Champions? Items like Choice Band (physical) and Choice Specs (special) multiply your damage output by 1.5x, but lock you into one move. Type-boosting plates and gems also add a damage multiplier. Held items stack with STAB and type effectiveness, so the right item on the right attacker matters a lot.
What is a critical hit and how does it change damage? A critical hit ignores the defender’s positive Defense or Special Defense stat stages and multiplies damage by 1.5x. Critical hits land at roughly a 1-in-24 base rate unless a move or ability raises the critical hit ratio. They can swing close games, but you cannot count on them in competitive play.
How does burn affect physical damage in Pokemon Champions? A burned Pokemon deals half damage with physical moves — the Burn status halves the effective Attack stat in the damage formula. This is one reason competitive players use Will-O-Wisp to neuter physical attackers. Special attackers are unaffected by burn’s damage penalty.
Do weather effects change damage output in Pokemon Champions? Yes. Sun boosts Fire-type moves by 1.5x and weakens Water-type moves by 0.5x. Rain does the reverse. Sandstorm and Snow don’t directly boost damage but raise Special Defense for Rock-types and Defense for Ice-types respectively. Weather teams are built around these multipliers.
What is a damage range and why does it matter competitively? A damage range is the minimum-to-maximum percentage of HP a move deals, factoring in the random roll (85-100% of max damage). Knowing the range tells you whether a move KOs in one or two hits. Competitive players use damage calculators to plan two-hit KO sequences and avoid being surprised in-game.
