Update: Sorry, we’ve missed the new Warrior skin!
SI:7 Anduin will be a part of Book of Heroes: Anduin bundle. The other four hero skins are references to characters from the Chinese 14th century historical novel “Romance of Three Kingdoms”. It was later referenced and adapted in many other novels, films or manga and many of the adaptations are very popular today. We only know that they’ll be obtainable by purchasing some sort of bundles, but we have no details yet. One thing is sure – we’re finally getting a new Rogue skin!
