While the original article mentioned crossword puzzles, our focus remains on maximizing your value in New Eridu.
This isn’t HoYoverse’s first generosity with top-tier agents; recall that Harumasa was available for free in version 1.4. The claiming process is typically simple: log in during the event period and navigate to the anniversary event page. There, you’ll be presented with a choice of one of the following six standard S-Rank agents:
The dedicated event interface will detail the agent selection and additional rewards, including W-Engines. Furthermore, progressing through the new main story chapter in Season 2 will grant fresh cosmetic outfits for your trusted assistants, Belle and Wise.
Standard Banner S-Rank Agent Analysis
Choosing the right agent is more than just picking a favorite; it’s a strategic decision that impacts your team’s performance for months. Let’s break down the options by their primary combat role and element to guide your choice.
Support & Enabler Specialists:
– Rina (Electric): The premier support for Electric damage-dealers, enhancing team damage output and PEN Ratio.
– Lycaon (Ice): A top-tier Stun agent who excels at breaking enemy stance, enabling your main DPS to unleash devastating attacks.
Damage & Anomaly Specialists:
– Grace (Electric): An Anomaly-focused agent who excels at applying and detonating Shock and Disorder effects, enabling powerful combo reactions like Abloom.
– Koleda (Fire): A Stun-focused agent who also brings solid Fire damage, useful for teams needing break effect support.
– Nekomata (Physical): A straightforward, high-damage Attack agent, excellent for new players needing reliable single-target damage.
– Soldier 11 (Fire): Another powerful Attack agent, ideal for players lacking a strong Fire DPS or who enjoy a direct, aggressive playstyle.
Strategic Selection Criteria:
1. Account Needs: Do you lack a dedicated Support, a reliable Stun breaker, or a main Damage dealer?
2. Elemental Coverage: Building teams around specific elements (like Mono-Electric) is highly effective. Choose an agent that strengthens your weakest element.
3. Playstyle Preference: Do you enjoy managing complex Anomaly effects (Grace), enabling your team (Rina, Lycaon), or dealing direct damage (Nekomata, Soldier 11)?
In-Depth Agent Evaluation & Team Synergy
To make an informed choice, understanding how these agents function in a team is crucial.
Rina: The Electric Support Powerhouse
Rina isn’t just a buffer; she’s a force multiplier for Electric teams. Her kit, which involves puppets Drusilla and Anastella, provides significant burst damage windows. The key is her ability to boost her squad’s PEN Ratio by up to 30%, a stat that ignores enemy defense. When paired with other Electric units, they gain an additional 10% Elemental Damage boost. She is arguably the best choice if you are investing in characters like Ellen or are planning to pull for future Electric DPS agents.
Lycaon: The Consistent Ice Enabler
Since his debut, Lycaon has remained a meta staple for his unparalleled efficiency in staggering foes. His value isn’t tied to complex mechanics but to consistent, reliable performance. He creates extended vulnerability phases for damage dealers like Hugo or any other Ice DPS. With proper investment in his W-Engine and Drive Discs, he can also contribute substantial damage while fulfilling his primary role.
Grace: Master of Anomaly Combos
Grace offers one of the most dynamic playstyles. She shines in teams built around applying and triggering elemental anomalies. Her synergy with Vivian to create the “Abloom” effect is a perfect example. This makes her exceptionally powerful against elite enemies and bosses with high health pools, where sustained anomaly damage shines. She is the ideal pick for players who already have core S-Rank attackers and want to explore advanced, reaction-based team compositions.
Advanced Selection Strategy & Common Pitfalls
Beyond initial impressions, your decision should account for long-term account health.
Account Progression Considerations:
– New Players: Nekomata or Soldier 11 offer the most immediate power spike to clear early content.
– Mid-Game Players: Focus on agents like Lycaon or Rina who enable specific team archetypes you are building towards.
– End-Game/Veterans: Grace or a duplicate of a key agent for unlocking higher-tier Chain Attacks (if duplicates are allowed) might offer the most value.
Common Mistakes to Avoid:
1. Choosing for Rarity Alone: An S-Rank that doesn’t fit your teams is less valuable than an A-Rank that perfectly complements them.
2. Ignoring Elemental Balance: Over-investing in one element (e.g., three Fire S-Ranks) can leave you vulnerable in content that resists it.
3. Underestimating Support/Enablers: Damage dealers are flashy, but a great support like Rina often provides more overall team damage increase.
4. Rushing the Decision: Log in, review your current roster and gear, then claim your agent. You typically have the entire event period to choose.
Final Recommendation: There is no single “best” pick. The best agent is the one that synergizes with your current favorite characters, covers your account’s weaknesses, and aligns with the team compositions you enjoy playing. Use this event as a strategic tool to refine your squad for the challenges of Season 2 and beyond.
