Drain Bite (move)

 Drain Bite (Japanese: きゅうけつき, Vampire) is a damage-dealing Ghost-type move created by WD for Generation C.

Effect
Drain Bite inflicts damage, and 50% of the damage dealt to the target is restored to the user. The amount of HP recovered is always rounded down. However, if this move deals 1 HP of damage, 1 HP will be restored to the user.

If Drain Bite breaks a Substitute, no HP will be restored to the user. If HP is restored to the user when its current HP is greater than its maximum HP, its current HP will be set equal to its maximum HP.

If used against a Pokémon with the ability Liquid Ooze, the user will lose HP as well. If the user has the Big Root as its held item, Mega Drain saps 30% more HP than it would have normally. Big Root does not increase damage dealt.
