How Relay Stone Works in Combat
Activation Conditions
Relay Stone activates when any character in the party is under a shield effect provided by Geo skills or artifacts. The moment the shield is applied, Geo damage and shield strength increase, creating a reliable buffer for mistake-tolerant play.
Interaction with Party Roles
Support characters typically maintain the shield, while damage dealers capitalize on the increased Geo damage. This clear division helps teams maintain pressure without sacrificing survivability, especially in prolonged encounters.
Best Characters for Relay Stone Builds
Core Geo Resonance Supporters
Zhongli excels at maintaining shields and enabling high damage output, while Noelle provides consistent protection and self-sustain. Albedo adds stacking buffs and team-wide enhancement, making him a flexible core for longer content.
Damage-Focused Options
Ganyu benefits from amplified Geo damage, turning her charged attacks into reliable DPS tools. When paired with a strong shield source, she can safely output while the team remains protected against enemy bursts.
Artifact and Constellation Considerations
Set Choices and Stats
Retracing 2 pieces paired with Instructor or Wanderer's Troupe 4 pieces give strong bonuses to shield strength and Geo damage. Main stats should prioritize Life for durability, while sands and goblets focus on defensive or Geo-crit stats depending on role.
Constellation Impact
Constellations that extend shield duration or grant on-use enhancements further stabilize the party. Characters like Zhongli gain additional utility, while Ganyu sees improved energy recharge and burst uptime through specific constellation tiers.
Optimizing Team Compositions Around Relay Stone
Balancing Offense and Defense
Teams should include at least one shield source and one Geo damage dealer, with optional flex slots for healing or crowd control. This balance ensures that players can tackle both scripted encounters and open-world threats without resource burnout.
Rotation and Timing
Players benefit from coordinating shield uptime with burst windows, ensuring that Geo damage peaks when buffs are active. Proper timing of swaps and elemental reactions further extends survivability and maximizes damage per second.
