［Summer’s Reverb］Cordie Skill Analysis

Blooming Thunder

Star Mine

Summer Cordie can potentially bring strong physical damage from Blooming Thunder and Star Mine, while also support allies by improving their hit chance and reducing enemy EVD. Both skills become powerful at high levels. However, her early performance can be frustrating due to random targeting for both damage and healing.

Additionally, the effectiveness of her buffing capabilities might be limited depending on targeting and activation frequency at lower levels. Overall, Summer Cordie has a potential for strong offense and support, but maximizing her effectiveness requires investment in skill upgrades and potentially having her Unique Weapon.

Let’s Liven it Up!

Resounding Applause

Let's Liven it Up! significantly boosts the attack of Summer Cordie's strongest teammate, but it activates slowly at lower levels and might not always target the optimal ally.

Resounding Applause turns Summer Cordie into a defensive powerhouse as the battle progresses, stacking DEF and M. DEF with each attack she deals or receives. However, it requires consistent action to reach its full potential.

Overall, these skills offer a strong mix of support and survivability, but some strategic thinking might be needed to maximize their effectiveness.

［Summer’s Reverb］Cordie Hard Counters

Ophelia

Her high HP and crit resist from Royal Guard's Honor make her very tanky against Cordie's physical attacks. Even more, her last stand ability (Royal Guard's Honor Lv.3) lets her survive a fatal blow, potentially saving the team. When this happens, Ophelia also buffs the team's P.DEF, further reducing Cordie's damage.

However, Cordie's high damage output and increasing defense can still be a threat. To maximize Ophelia's effectiveness, build her tanky, consider having healers and defenders on your team.

Belle

Belle's skills can potentially hard counter Summer Cordie in a few ways. Belle's Explosive End targets the highest ATK enemy, potentially removing Cordie's buff and inflicting bleed. Fire Dragon's Wrath prioritizes low HP enemies, which can be useful after Cordie uses Blooming Thunder. Vengeful Blaze can help Belle survive Cordie's burst damage.

However, Belle's effectiveness depends on factors like team composition and turn order.

Fenny

Fenny's Jamming Scattershot can disrupt Summer Cordie's buffing abilities and deal heavy AoE damage, potentially taking out weaker enemies before they can act. Magic Permeator focuses on high HP targets, likely taking out Summer Cordie due to her defensive buffs. The Erosion DoT(Damage over Time) from Magic Permeator can further hinder her.

However, Summer Cordie's buffs can still be effective if applied before Fenny disrupts them and her tankiness can make her a challenge.

［Summer’s Reverb］Cordie Sample Counter Teams

Azure Affinity Team

Debuffer	Attacker	Healer	Attacker	Buffer
Soltina	Florence	Fortina	Summer Nina	Sivi

This team has a fighting chance against Summer Cordie, but it hinges on being faster. Florence's critical hits and defense reduction can weaken Cordie, while Fortina's shields and Summer Nina's defense buffs can protect the team. Sivi can dispel Cordie's buffs and boost the team's damage, while Soltina might put enemies to sleep or even take out Cordie entirely. The key is to act first, focus on taking down Cordie quickly with Florence and Soltina, and use Sivi to dispel her buffs. With some luck and good timing, this team can counter the Summer gunslinger.

Mixed Offensive and Defensive Team

Attacker	Debuffer	Tank	Buffer	Attacker
Belle	Fenny	Ophelia	Kaguya	Amleth

Kaguya's buffs can significantly boost your team's damage output against Summer Cordie, while her debuffs have a chance to weaken Cordie's attacks. The team still faces challenges from Summer Cordie's random targeting and burst damage. Focus on debuffing Cordie with Fenny and prioritize taking her down first. Kaguya's buffs can make Belle and Amleth hit even harder, so use their skills strategically to burst down Cordie quickly. Consider using Ophelia as a decoy with her Keeper of Oaths to protect your damage dealers. With some luck and good timing, this team with Kaguya can conquer Summer Cordie.

Witches Not To Use Against ［Summer’s Reverb］Cordie

Dian

Characters that relies on buffs: Summer Cordie's Blooming Thunder can negate Dian's evasion buff, making her vulnerable despite Dian's own Heart of Servitude skill. Additionally, Summer Cordie's Star Mine can heal allies with low HP, potentially preventing Dian from activating her powerful Cursed Bullet which relies on her being injured.

Finally, Summer Cordie's growing defenses thanks to Resounding Applause might make it difficult for Dian to deal significant damage later in the fight.

Morgana

Characters who are self-damaging or needed to be at low HP: Morgana's damage relies on her self-damaging skills, Préachán and Bó Rua. However, Summer Cordie's Star Mine can heal allies with low HP, potentially preventing Morgana from reaching the critical health point to activate the high damage portions of her skills. Additionally, Summer Cordie's growing defenses thanks to Resounding Applause might make it hard for Morgana to deal significant damage later in the fight, especially since Morgana also injures herself with her attacks.

Tips for Beating ［Summer’s Reverb］Cordie

Use Debuffers

Debuffers can weaken her allies by lowering their accuracy, evasion, or attack power, making them less effective and mitigating the buffs from Blooming Thunder and Let's Liven it Up!

Equip Debuff ACC and EVD Runes

Since Blooming Thunder increases the chance to hit and decreases the chance to evade of her allies, consider using runes that debuff accuracy and evasion on those allies. This will make them miss attacks more often and be easier to hit yourself.

Use High Damage Dealers

Don't forget about damage dealers! Characters with high single-target DPS can take down buffed allies quickly, while those with spread damage can lessen the impact of Star Mine's random attacks.
