Light Screen is a Psychic-type non-damaging move with no power or accuracy component because it doesn't deal direct damage. When used, Light Screen halves the damage received from special attacks for the user's team for five turns in battle. This effect can be crucial in providing additional resilience against special attackers. Additionally, Light Screen's duration can be extended to eight turns if the user is holding the Light Clay item. Light Screen is commonly used in both casual and competitive play to bolster team defenses and create strategic advantages.
