There are various attacks in the Smash Bros. series that cause the slash effect. Usually caused by sharp objects, slash attacks are buffed by Slash Attack stickers and defended against by Slash Resistance ones. Slash attacks can be easily identified by their boomerang-shaped impending angle indicator (though grass attacks use this as well); while the impact sound is also often a clue, it cannot be used definitively (for example, many of Toon Link's sword attacks do not sound like slash attacks).
