Solar Blade (Japanese: ソーラーブレード Solar Blade) is a damage-dealing Grass-type move introduced in Generation VII. In Generation VII, it was the signature move of Lurantis. It is TM12 in Generation VIII.
Solar Blade charges up sunlight on the first turn and then unleashes the power as an attack on the second.
Solar Blade will not need a turn to charge if used during harsh sunlight. It will have its power halved if used during rain, hail, or sandstorm.
If a Pokémon holding a Power Herb uses Solar Blade, it will consume the Power Herb to execute Solar Blade in one turn. If there is harsh sunlight, the Power Herb will not be consumed.
