From Bulbapedia, the community-driven Pokémon encyclopedia.

Synthesis (Japanese: こうごうせい Photosynthesis) is a non-damaging Grass-type move introduced in Generation II.

Effect

Generation II

Synthesis restores the user's current HP based on the weather and time of day. In morning and night, during no weather it restores ¼ total HP, during harsh sunlight it restores ½ total HP, and during other weather it restores ⅛ total HP, rounded down. Except in link battles, the move restores twice as much HP during the daytime.

Generation III onwards

Synthesis restores the user's current HP based on the weather in the battle. During no weather or during strong winds, it restores ½ total HP, during harsh sunlight, it restores ⅔ total HP, and during other weather, it restores ¼ total HP, rounded down.

Synthesis can be used as the second move of a Pokémon Contest combination, with the user gaining 1 bonus appeal point if Sunny Day was used in the previous turn. It is also part of a Contest Spectacular combination and will give an extra three appeal points if the move Sunny Day was used in the prior turn.

If powered up by a Grassium Z into Z-Synthesis, all of the user's lowered stats are reset.
