  • Caesar Overview

Caesar King is an S-Rank Physical Defense Agent from the Sons of Calydon who dominates the frontline with superior protection and elite team-wide offensive amping. Unlike traditional defenders who focus purely on damage mitigation, Caesar acts as a premier "force multiplier" for the squad, providing unparalleled safety while significantly boosting the damage output of her allies. Her kit revolves around the Radiant Aegis system; she grants a specialized shield to the active character that provides a massive ATK buff and high-level Anti-Interrupt protection.

While under the protection of the Radiant Aegis, teammates can ignore most enemy knockbacks and maintain relentless pressure on the field. Caesar can manually refresh this shield and trigger her signature Parry Counter by perfectly timing her EX Special Attack or entering via Defensive Assist. Landing the finishing blow of her Overpowered Shield Bash following a successful parry applies a potent 25% DMG Taken debuff to nearby enemies for 30 seconds. This ensures that even the most resilient bosses become vulnerable to the team's concentrated burst damage window.

Her additional Core ability is activated when Caesar is paired with another Physical Agent or a member of the Sons of Calydon. When active, her presence grants the team increased survivability and amplified daze application. This utility is further enhanced if Caesar’s Impact stat exceeds 150, making Impact her most vital stat for both stun efficiency and the scaling of her shield’s offensive buffs. Using Caesar’s Chain Attack or Ultimate delivers a thunderous, explosive shield strike that deals heavy Physical DMG while instantly refreshing her royal protection for the entire squad.

Caesar Skill Priority

Below are the best skill priorities for Caesar:

SkillPriority
Core Skill★★★★★ (Top)
Special Attack★★★★★ (Top)
Assist★★★★☆ (Top)
Basic Attack★★★☆☆ (Mid)
Chain Attack★★☆☆☆ (Low)
Dodge★☆☆☆☆ (Low)

Caesar King gets the most value from her Core Skill, as it directly dictates the strength of her Radiant Aegis shield and determines the scaling of the team-wide ATK buff. Afterward, you should focus heavily on her Special Attack, which is her primary tool for triggering Perfect Blocks and refreshing her defensive utility via EX Special Attack: Parry Counter. Unlike most defenders, her Assist is equally essential because her primary loop involves switching in with a Defensive Assist to deal massive Daze DMG and trigger her additional debuffs. Because Caesar is a reactive frontliner, you’ll be spending most of your time actively timing her counters to keep the enemy debuffed and the squad’s offensive momentum at its peak!

Caesar Best W-Engines

As a Defense Agent who serves as a powerhouse for both team protection and offensive utility, Caesar wants as much Impact as possible to maximize the durability of her shields and the team-wide damage buffs from her Core Skill. Being a character whose kit revolves around authoritative frontline presence and executing high-reward Perfect Blocks, her Signature W-Engine, Tusks of Fury is the premier choice to provide Caesar with massive Impact while granting unique stacks that significantly boost the ATK and DMG of the entire squad. While accessible alternatives like Original Transmorpher or Spring Embrace offer excellent survivability and energy utility, Tusks of Fury remains highly recommended if you wish to maximize her potential as a top-tier offensive support.

Caesar Best Disk Drives Sets

As a Defense Agent who provides elite team-wide protection and massive offensive utility, Caesar is best suited for 4-Piece Drive Disc Sets that amplify squad damage or maximize her support capabilities, notably Astral Voice, Proto Punk, and Freedom Blues. Astral Voice stands as her premier choice in high-frequency rotation teams, as its stackable team-wide DMG buff can be easily maintained through consistent Quick Assists. For a more defensive and straightforward approach, Proto Punk remains a top-tier alternative that triggers a powerful squad-wide DMG bonus whenever she performs a Defensive Assist or Perfect Block. If you are running her in a specialized Anomaly-focused squad, Freedom Blues is highly effective for shredding enemy Anomaly RES with her EX Special Attacks. Regardless of your 4-Piece choice, you should always combine it with a 2-Piece Shockstar Disco, King of the Summit, or Swing Jazz set; the extra Impact, Daze, or Energy Regen significantly increases the durability of her shields and the speed at which she can neutralize high-threat targets.

Caesar Best Teams

When choosing the best team for Caesar, your primary goal is to activate her Additional Core Skill, which requires pairing her with at least one teammate who can trigger a Defensive Assist or belongs to the Sons of Calydon faction. Beyond this technical requirement, you should look for high-output damage dealers who suffer from long, vulnerable attack animations; Caesar’s specialized anti-interrupt shield allows these characters to complete their full combos without being staggered, effectively increasing your team’s total DPS uptime. Additionally, because Caesar functions as a hybrid between a Defense and Stun agent, you have the flexibility to replace a traditional stunner entirely, opening up the third slot for a dedicated Support to layer more buffs or an Anomaly agent to capitalize on her resistance shred. Ultimately, the best squad for her is one that values aggressive on-field time and can capitalize on the massive 1,000 flat ATK boost her shield provides to the active character.
