In battle
Mega Sol causes all moves used by the Pokémon with this Ability to behave as though the weather were harsh sunlight, regardless of the actual weather on the field. This means that, when used by a Pokémon with Mega Sol:
- Solar Beam and Solar Blade are executed in a single turn, instead of requiring a turn to charge.
- Weather Ball is a Fire-type move with a base power of 100.
- Synthesis, Moonlight, and Morning Sun restore ⅔ of the Pokémon's maximum HP.
- Thunder and Hurricane have their accuracy reduced to 50%.
- All Fire-type moves used by the Pokémon have their power increased by 50%, and all Water-type moves used by the Pokémon have their power decreased by 50%.
- The reduction in the accuracy of the user's movements caused by the Abilities Sand Veil and Snow Cloak is ignored.
Because Mega Sol does not alter the weather itself, it is unaffected by the weather-negating effect of Cloud Nine. It also bypasses the Special Defense boost granted to Rock-type Pokémon during sandstorm and the Defense boost granted to Ice-type Pokémon during snow. Additionally, Solar Beam and Solar Blade do not have their power halved under rain, snow, or sandstorm when used by a Pokémon with Mega Sol.
If a Pokémon with Mega Sol uses Growth and harsh sunlight isn't already on the field, the move won't have any effect.
