When used by a Ghost-type, the user sacrifices half of its max HP to sap the target by 1/4 of its max HP per turn. When used by anything else, the user's Speed is decreased by 1 stage and its Attack and Defense are increased by 1 stage.
The target is forced to use its last attack for the next 2-6 turns. The effects of this move will end immediately if the target runs out of PP for the repeated attack. In double battles, a Pokemon who has received an Encore will target a random opponent with single-target attacks.
The user steals 1/8 of the target's max HP until the target is switched out, is KO'ed, or uses Rapid Spin; does not work against Grass-type Pokemon or Pokemon behind Substitutes.
The user generates another move depending on the battle's current terrain. It generates Stun Spore in grass and tall grass (as well as in puddles and very shallow water), Razor Leaf in very tall grass, Surf while surfing on top of river and ocean water, Bubblebeam while surfing on top of pond water, Hydro Pump while diving underwater, Rock Slide on any rocky outdoor terrain, Shadow Ball inside of caves, Earthquake on beach and desert sand, and Swift everywhere else (including link battles).
