Rappa stands out as an AoE Break DMG specialist in Honkai: Star Rail, joining the niche group of DPS characters alongside Boothill and Firefly. Her key strength lies in her ability to deal impressive Super Break DMG, surpassing even Firefly in that aspect, while also providing AoE capabilities due to her role as an Erudition character. Additionally, Rappa's talent lets her reduce toughness on enemies that aren't even weak to Imaginary as long as one enemy is already weakness broken, making her incredibly useful in scenarios with large enemy waves, like Pure Fiction.
