Simple Beam is a Normal-type move with no power and 100% accuracy. When used, it changes the target's Ability to Simple, which doubles the effects of stat changes on the target. This can be strategically significant in battles, as it can either weaken opponents by amplifying negative stat changes or strengthen allies by doubling positive stat boosts. Simple Beam is primarily used for its unique ability-altering effect rather than for dealing damage. It can be particularly effective when used in combination with moves or abilities that involve stat adjustments.
