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-C.

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-C, 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-C, 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-C (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.

Calculadora de daño de Pokémon Champions

ChampDex es una calculadora de daño gratuita para Pokémon Champions, hecha para el formato Reg M-C. Aplica la fórmula de daño exacta de Champions, Stat Points en lugar de EVs, nivel 50, Megaevolución, clima, objetos y movimientos de área, y muestra cada modificador para que puedas fiarte del rango de KO. Los números se verifican a diario contra la calculadora de Smogon.

Preguntas frecuentes

¿Cómo se calcula el daño en Pokémon Champions?: Pokémon Champions usa un sistema de Stat Points en lugar de EVs tradicionales. El daño depende del nivel del atacante (siempre 50), de su Ataque o Ataque Especial, de la potencia base del movimiento y de la defensa correspondiente del rival, multiplicado por STAB, efectividad de tipo, clima, crítico y modificadores de área. La calculadora de ChampDex aplica la fórmula completa de Champions para que puedas fiarte de cada rango de KO en Reg M-C.
¿Qué es el STAB en Pokémon Champions?: El STAB (bonificación por tipo igual) es un multiplicador de 1,5× que se aplica cuando un Pokémon usa un movimiento de un tipo que coincide con uno de los suyos. Adaptable lo sube a 2×. La calculadora aplica el STAB automáticamente según los tipos del atacante.
¿Pokémon Champions usa EVs o Stat Points?: Pokémon Champions usa un sistema de Stat Points con un presupuesto total de 66 puntos y un tope de 32 por estadística. Cada punto suma 1 a la estadística final al nivel 50. La calculadora de ChampDex admite Stat Points directamente, y el Conversor de EVs traduce los spreads de EVs de Smogon a sus equivalentes en Champions con la regla oficial: 4 EVs para el primer SP y 8 EVs por cada SP adicional.
¿Es precisa esta calculadora de daño para torneos de Champions?: Sí. La calculadora de ChampDex usa la fórmula de daño exacta verificada en Serebii y Bulbapedia para Reg M-C, el formato actual de Champions. Contempla STAB, clima (lluvia, sol, tormenta de arena y nieve), críticos, la reducción de los movimientos de área (0,75× en dobles con varios objetivos) y los cambios de estadísticas. Todos los modificadores aparecen en el desglose para que puedas verificar cada paso.
¿La calculadora admite la Megaevolución?: Sí. La Megaevolución es la única mecánica de combate legal en Reg M-C, y la calculadora es totalmente compatible con las Megaformas: cambia a Mega Charizard Y, Mega Gardevoir o cualquier otra Mega legal en Champions y se aplican automáticamente las estadísticas mejoradas, el cambio de habilidad y el nuevo tipo.
¿La calculadora admite la Teracristalización?: Todavía no. La Teracristalización no es legal en Reg M-C (Champions es solo Mega), así que los controles de Tera están ocultos para no generar números que el juego no puede reproducir. Cuando Tera sea legal en una regulación futura, la fórmula de daño ya lo admite y la interfaz se mostrará automáticamente.
¿La calculadora de Pokémon Champions es gratis?: Sí. La calculadora de daño de ChampDex es gratuita, no requiere cuenta ni inicio de sesión, y no tiene muros de pago ni anuncios. Todas las funciones están desbloqueadas para todo el mundo.
