Leech Seed (move)/Effect/Generation III Onward

Leech Seed will now drain HP at the end of each turn.

In battles involving multiple Pokémon, Leech Seed will only heal the Pokémon that is in the same position as the Pokémon that originally used Leech Seed was in. If no Pokémon is in that position (for example, if it fainted and could not be replaced), Leech Seed will not take any health from the seeded Pokémon. However, if a Pokémon is later able to occupy that position (if it was revived), Leech Seed will once again sap HP from the seeded Pokémon. While a Pokémon is seeded, even if it cannot have its health drained due to there being no Pokémon in the appropriate slot to drain its HP, it cannot be affected by Leech Seed again.

Leech Seed can be used as part of a Pokémon Contest combination, with the user gaining an extra two appeal points if was used in the prior turn. It is also part of a Contest Spectacular combination, with the user gaining an extra three appeal points if was used in the prior turn.

If the target has the Ability, the user takes damage instead of restoring HP. If the user is under the effect of, Leech Seed will not restore any of the user's HP. However, the effect damage will be dealt normally. If the user has a Big Root as its held item, it will recover 30% more HP than it normally would. Big Root does not increase damage dealt. All other effects remain the same.

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