Frequently asked questions

How do I calculate damage in Pokemon Champions?

Pokemon Champions uses a stat-point system instead of traditional EVs. Damage depends on the attacker's level (always 50), its Attack or Special Attack stat, the move's base power, and the defender's matching defense, multiplied by STAB, type effectiveness, weather, crit, and spread modifiers. The ChampDex calculator runs the full Champions-accurate formula so you trust every KO range in Reg M-B.

What is STAB in Pokemon Champions?

STAB (Same-Type Attack Bonus) is a 1.5x multiplier applied when a Pokemon uses a move of a type matching one of its own types. Adaptability makes it 2x. The calculator applies STAB automatically based on the attacker's types.

Does Pokemon Champions use EVs or stat points?

Pokemon Champions uses a stat-point system with a 66-point total budget and a 32-point per-stat cap. Each stat point adds 1 to the final stat at Level 50. The ChampDex calculator supports stat points directly, and the EV Converter tool translates Smogon EV spreads into Champions equivalents using the official 4-EVs-for-the-first-SP / 8-EVs-per-extra-SP conversion rule.

Is this damage calculator accurate for Champions tournaments?

Yes. The ChampDex calculator uses the exact damage formula verified from Serebii and Bulbapedia for Reg M-B, the current Champions format. It handles STAB, weather (Rain/Sun/Sand/Snow), crit, spread-move reduction (0.75x for Doubles multi-target moves), and stat stages. All modifiers are shown in the breakdown so you can verify every step.

Does the calculator support Mega Evolution?

Yes. Mega Evolution is the only battle gimmick legal in Reg M-B, and the calc fully supports Mega forms — switch to Mega Charizard Y, Mega Gardevoir, or any other Champions-legal Mega and the boosted stats, changed ability, and updated typing all apply automatically.

Does the calculator support Terastallization?

Not yet. Terastallization isn't legal in Reg M-B (Champions is Mega-only), so the Tera controls are hidden to avoid producing damage numbers the game can't reproduce. When Tera becomes legal in a future regulation, the damage formula already supports it and the UI will unhide automatically.

Is the Pokemon Champions calculator free?

Yes. The ChampDex damage calculator is free, requires no login or account, has zero paywalls, and no ads. All features are unlocked for everyone.
