Achieving high-level completion in the Arbitration Checkmate stage relies on the specific synergy between an E2 Phynon and a base-level Keridra. By focusing on Phynon’s increased damage output at the second eidolon level, players can effectively bypass the defensive thresholds of the encounter. This strategy prioritizes maintaining consistent pressure through Phynon while using Keridra’s utility to stabilize the team’s performance against the stage's unique mechanics and scaling difficulty.
Utilizing E2 Phynon for DPS Optimization
The core of this strategy centers on Phynon’s E2, which significantly elevates his offensive potential. At this investment level, Phynon becomes the primary catalyst for clearing the Arbitration Checkmate waves efficiently.
- Eidolon Impact: The E2 upgrade provides a critical damage modifier that allows Phynon to break through enemy resistances more reliably.
- Rotation Priority: Always prioritize Phynon’s combat skills to maximize the uptime of his enhanced damage state.
- Energy Management: Ensure Phynon has sufficient energy regeneration to cycle his ultimate frequently, as this is vital for maintaining the damage output required to clear the stage before the turn limit.
Integrating Base-Level Keridra
While Phynon acts as the primary damage dealer, Keridra provides the essential support required to sustain the team. Even at E0 (base level), Keridra’s kit offers enough utility to complement the team’s overall output.
- Utility Focus: Use Keridra primarily for utility and support rather than raw damage. Her presence helps manage incoming pressure and ensures the team remains healthy throughout the encounter.
- Synergy: Keridra’s ability to manipulate the field allows Phynon to focus entirely on striking targets, minimizing downtime and wasted resources.
Arbitration Checkmate Execution Tips
Success in this mode requires precise timing and understanding the boss's patterns. Follow these guidelines to optimize your run:
| Strategy Focus | Action Item |
|---|---|
| Damage Window | Save Phynon’s ultimate for when the enemy is in a vulnerable state. |
| Support Timing | Deploy Keridra’s skills during high-damage phases from the enemy to mitigate losses. |
| Turn Management | Focus fire on priority targets to reduce the total number of turns spent in combat. |
Managing Difficulty Spikes
The Arbitration Checkmate encounter scales quickly. If you find your team struggling, verify that your relic sets are optimized for damage percentage rather than just flat stats. Phynon benefits significantly from gear that boosts his specific damage type, allowing the E2 bonuses to scale more effectively. Always monitor the turn counter to ensure that your support rotations do not consume too much time, as the stage punishes slow play.
