How to use the Pokemon Champions damage calculator
Set the attacker on the left and the defender on the right. Picking a Pokemon loads its most common set from the ladder, so you can run a calc in two clicks and adjust from there. The middle panel shows every move of the attacker against the defender; switch to Defender hits back to see the hits going the other way.
Each result shows the damage as a share of the target's HP, the knockout chance, the sixteen damage rolls and a one line summary you can paste into a team report. The link in your address bar updates as you go, so copying it shares the exact calc.
VGC doubles modifiers in the damage calc
- Spread moves do 0.75 times damage when they hit more than one target in doubles.
- Helping Hand multiplies the partner's move by 1.5.
- Friend Guard cuts damage to the partner by a quarter.
- Reflect and Light Screen cut physical or special damage by about a third in doubles (not a half as in singles), and Aurora Veil does both.
- Weather and terrain boost Fire and Water in sun and rain by 1.5, and terrain boosts its matching type by 1.3 for grounded attackers.
- Intimidate lowers Attack by one stage on entry; set a -1 Attack boost on the attacker to account for it.
Stat Points in damage calcs
Champions spreads are written in Stat Points, from 0 to 32 per stat with 66 in total. Enter them as they are; there is no EV conversion to do. At level 50, each Stat Point adds one point to the stat, so moving 8 SP from Attack into HP trades exactly 8 Attack for 8 HP. If you have an old EV spread, the stat calculator converts it to the Stat Points that produce the same stats.

Reading the KO chance and damage rolls
"Guaranteed OHKO" means all sixteen rolls knock out the target from full HP. "75% chance to OHKO" means twelve of the sixteen rolls do. "Guaranteed 2HKO" means two hits always KO, counting no recovery. Items like Sitrus Berry and Leftovers are counted when the calculator works out multi hit KOs, so a 2HKO can turn into a 3HKO when the defender holds a berry.
For speed questions (who moves first, and with Tailwind or Trick Room) use the speed tiers, and to check whole team matchups go back to the team builder.
Damage calculator questions
Is this the same math as the Showdown damage calculator?
Yes. The calculator runs the open source @smogon/calc engine (version 0.12) with its Pokemon Champions mechanics, the same engine behind the Showdown calculator. The difference is the page around it: Stat Points instead of EVs, doubles as the default, and loading straight from your team.
Does it include the spread move damage reduction?
In doubles, moves that hit more than one target, such as Earthquake, Heat Wave, Rock Slide or Dazzling Gleam, do 0.75 times damage. The calculator applies it automatically when Doubles is selected. Switch to Singles to see the full damage.
Why do I see sixteen numbers under each result?
Every attack picks one of sixteen random rolls between 85% and 100% of its maximum damage. The list shows all sixteen, so you can count how many of them knock out the target, which is what the KO chance line summarizes.
How do I calc a Mega Evolution?
Pick the Mega forme by name, for example Charizard-Mega-Y or Garchomp-Mega-Z. It gets the Mega Stone, stats and ability automatically. Abilities that set weather or terrain on entry, such as Drought, Drizzle or Grassy Surge, switch the battle panel to that weather or terrain automatically; change it there if the opposing setter came in later.
