Leech Seed (Japanese: やどりぎのタネ Mistletoe Seed) is a non-damaging Grass-type move.
Leech Seed plants a seed on the target. After a target under the effect of Leech Seed takes its turn, ⅛ of its HP will be drained (rounded down, but not less than 1), and the same amount of HP will be restored to the target's opponent (even if it was not the Pokémon that originally used the attack). Recurrent Leech Seed draining will not occur if the seeded Pokémon defeats the target. Unlike other types of damage, the recurrent damage done by Leech Seed can exceed the target's current HP. Leech Seed will not work against Grass-type Pokémon, and attempts to seed an already-seeded Pokémon will fail.
