Synthesis is a Grass-type move with no power or accuracy value since it is a status move. It restores the user's HP by a variable amount depending on the weather conditions. Under normal weather, Synthesis heals 50% of the user's maximum HP. During sunny weather, it restores 66.7% of the user's maximum HP, and during other weather conditions (such as rain, hail, or sandstorm), it restores only 25% of the user's maximum HP. Synthesis is widely used by both defensive and supportive Pokémon due to its reliable healing capability.
