Rewards
Shiyu Defense Boost rewards include every rare upgrade material in Zenless Zone Zero, with guaranteed S-rank completion ensuring nothing is missed. Each section—Stable, Disputed, and Critical—delivers high-value loot that boosts long-term performance across all ZZZ content. Every reward has gameplay utility, and ChaosBoost ensures it's all collected through expert execution.
