Leech Seed is an offensive Grass-type move.
At the end of each turn a target under the effect of Leech Seed will have 1/16 of its HP drained, 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).
Leech Seed does not work on Grass-types.
If the target has the Ability Liquid Ooze, the user takes damage instead of restoring HP.
If the user is under the effect of Heal Block, Leech Seed will not restore any of the user's HP. However, the effect damage will be dealt normally.
If the user is holding a Big Root, it will recover 30% more HP than it normally would. Big Root does not increase damage dealt. All other effects remain the same.
