With over ten playable characters in Chained Echoes, competition for party slots is fierce. However, one character that never left my lineup from start to finish was Senna. She excels in both agility and damage output, making her one of the strongest characters in the game. This guide will cover everything you need to optimize Senna, from gearing to stat allocation, skill prioritization, and team synergy, ensuring she reaches her full potential.

Gearing Up for Maximum Effectiveness

Senna’s equipment follows a vertical progression system, meaning you should always equip the highest-star-rated weapon and armor available. As soon as you find new gear, take it to the nearest Anvil for an upgrade to ensure you stay ahead of the curve.

Best Accessory

For the accessory slot, the best choice is the Bracelet of Power, which grants a +20 attack boost. This is an endgame item, so if you’re still progressing through the story, use an item that boosts Agility—such as the Winged Cape—to increase the number of turns Senna gets in battle.

Agility Cap Considerations

Chained Echoes caps Agility at 50, making it essential to reach this threshold. Since weapons and armor don’t naturally provide Agility, you will need to use Agility Crystals or stat nodes to achieve the cap. Having higher Agility ensures Senna takes more turns, directly increasing her overall damage output.

Optimizing Stat Nodes

Outside of gear, Stat Nodes provide the only permanent stat increases.

1. Prioritize Agility whenever possible—these are rare, so purchase them immediately when available.
2. Invest in HP next, as Senna has a naturally low HP pool. This will help her survive attacks that would otherwise take her out.
3. TP should follow, ensuring that Senna doesn’t run out of energy for her abilities.
4. Strength and Critical Chance should be the next focus, maximizing her offensive potential.

Best Passives for Senna

Not all passives are worth the investment. Killer passives (bonus damage against specific enemy types) are a trap—they provide minimal benefit and should be ignored.

Optimal Passive Selection:

1. Agility Up – More turns = more damage.
2. Attack Up – Straightforward power boost.
3. Critical Up – Increases crit rate, making attacks deadlier.
4. Crit Damage Up – Enhances the potency of critical hits.
5. TP Gain Up – Restores 30 TP per attack instead of the default 10, significantly improving resource management.

Top Skills to Use

Senna’s skill set is built around high-speed, high-damage, and utility options that help manage Overdrive and sustain the party.

1. X-Slash – One of the best Tier 1 skills, applying Bleed for consistent damage over time.
2. Hilfer – Useful early game for farming crafting materials and managing Overdrive.
3. Nukitsuke – Grants a 15% critical buff to all allies.
4. Dragonfang – Highest-damage skill in the game when all hits are combined.
5. Quickstep – Allows Senna to act multiple times before enemies get a turn.
6. Calm Water – Enables Senna to dodge all attacks, making her extremely survivable.

Since aggro in Chained Echoes is based on damage output, Senna frequently draws enemy attention. Using Calm Water ensures she can maintain high damage without the risk of getting KO’d.

Building the Perfect Team Around Senna

Senna shines when supported by the right teammates. The following party setup enhances her strengths and provides the necessary buffs and debuffs to maximize her effectiveness.

Key Team Members:

• Glenn – Essential for Armor Break, reducing enemy defense by 20%, and Land Energy for TP sustain. He can also use Oil Slash, creating a fire weakness for additional elemental exploitation.
• Lin – Gains access to Elemental Codes, allowing the party to exploit enemy weaknesses. Using the Ruined Knight emblem provides access to both Light and Dark elements.
• Victor – Provides the Poetic March buff (+14% damage) and Heroic Ode, which boosts attack, agility, and critical hit chance by 15%. His Valor Minuet helps replenish TP, and his Limit Break fully restores TP for the whole party.
• Mika – Her Double Steps buff stacks with Agility buffs, allowing Senna to attack two to four times before enemies act. Her Strength Dance functions similarly to Poetic March, freeing up Victor for healing if necessary.

Senna’s Best Emblem

The Bandit Emblem is the best choice for Senna, helping her hit the 50 Agility cap without needing additional investment in stat nodes. The emblem’s skill set isn’t necessary, but the stat bonuses are invaluable.

Crystal Setup: Melding for Maximum Damage

For maximum effectiveness, you should meld your weapons and armor with the following crystals:

1. Critical Up – Boosts crit rate by 30%.
2. Damage Up – Increases overall damage output.
3. Attack Up – Provides a raw damage boost.

Note: As of patch 1.052, the Critical Damage Crystal appears to be bugged and has an abnormally low drop rate. If you’re struggling to find it, use Katana Master as a substitute until the issue is addressed.

Battle Strategy: Executing the Plan

Every fight follows a simple but effective rotation to maximize Senna’s damage output:

1. Turn 1 – Use Quickstep on Senna.
2. Turn 2 (Mika) – Use Double Steps.
3. Turn 3 (Senna) – Activate Calm Water.
4. Turn 4 (Lin) – If the enemy has a weakness, apply the corresponding Elemental Code.
5. Turn 5 (Victor) – Use Heroic Ode for the strongest stat buffs.
6. Turn 6 (Senna) – Apply Nukitsuke for a crit buff to the whole team.
7. Turn 7 (Mika) – Use Strength Dance.
8. Turn 8 (Glenn) – Use Armor Break to weaken the enemy.
9. From Here On – Spam Dragonfang while reapplying buffs and debuffs as needed.

If the enemy has no elemental weakness, swap Lin for Glenn early and use Oil Slash. Then, when Glenn gets another turn, switch back to Lin and apply Fire Code to maintain 100% bonus damage.

Final Thoughts

Senna’s high agility, powerful multi-hit attacks, and evasion abilities make her one of the strongest characters in Chained Echoes. By optimizing her gear, stat nodes, passives, and team composition, you can turn her into a turn-spamming powerhouse capable of dismantling any boss fight with ease.
