The Star-Studded Cast banner in Zenless Zone Zero serves as the standard Gacha system where players can obtain a variety of high-rarity characters and W-Engines. While they may not at all times amount to limited-time banner characters or W-engines, it is an excellent way for players to build a robust roster, while considering synergies between certain characters. The pity system ensures that even with less than optimal luck, players will eventually obtain high-rarity items.
