Boom are cosmetic items that modify the damage particles towards opponent Little Legends. Like Little Legend, they come in 3 tiers of increasing impact and style. First tier changes your Little Legend attack, second tier will also change your champions attacks, and last tier will add additional effects to the projectile.
