Rhodagn Strategy and Tips

Control a Character with Ranged Attacks

Rhodagn heavily favors close-quarters combat. By taking control of a ranged character like Perlica, Wulfgard, and even Ardelia, you can maintain a safe distance when he charges in, significantly reducing the damage you take.

Watch Out for the Blast Zone

When Rhodagn winds up an attack, a red danger zone appears, accompanied by a smaller inner circle expanding outward. If you're stuck in the blast radius, the hit will connect the exact moment the inner circle meets the outer edge. Use this visual cue to time your dodges perfectly.

Time Your Counters

Characters like Snowshine or Akekuri can drastically reduce incoming damage and counter-attack if their Battle Skills are timed right. Anticipating when Rhodagn will land will massively improve your success of countering him, so keep your eyes peeled.

Unleash Burst Damage During Stagger

When Staggered, Rhodagn is immobilized and takes increased damage. This is your window to unleash your hardest-hitting Battle Skills and Ultimates. During his normal phases, focus on building up the Stagger gauge using Final Strikes and Combo Skills.

Hide Behind Walls to Survive the Ultimate

After shifting forms, if Rhodagn leaps to the center of the arena, brace yourself, he's charging his ultimate attack. He'll summon four protective walls while he winds up; duck behind one to survive the blast. Ranged characters can actually keep attacking from behind this cover. If you're feeling bold, you can technically "Perfect Dodge" this attack, but the timing is tight.

Recover SP by Chain-Dodging the Flamethrower

Rhodagn's flamethrower is lethal since it hits multiple times and inflicts Combustion. However, you can turn this to your advantage by continuously dodging the flames. Not only do you avoid damage, but you also rapidly recover your SP. Repeatedly dodging left or right makes this much easier.

Dodge Backward to Protect Your AI Teammates

While strafing left or right is great for SP farming, it causes Rhodagn to swing the flamethrower in a wide arc, which will likely roast your AI-controlled allies. If your team is taking a beating, dodging backward to pull him away is a safer tactical choice.

Rhodagn's Attack Patterns and Cue

A Two‑Stage Showdown

Rhodagn starts in Phase 1, but after his health drops to a certain point, a brief cutscene triggers, signaling the start of Phase 2. He always opens Phase 2 with his ultimate move, and his entire moveset becomes much more aggressive.

Tips!	The mid-fight cutscene can be skipped!

Phase 1: Keep Your Distance and Dodge

In Phase 1, Rhodagn relies on heavy melee strikes and sweeping AoE attacks. Simply dodge the AoEs and maintain distance to easily evade his melee combos. Keep an eye out for his double-swipe into a slam.The final slam can be interrupted if you hit him with a skill.

Dodge the Opening Slam

Rhodagn always starts the fight with a Jump Press. He leaps into the air and crashes down after a short delay, covering a massive area that's hard to simply walk out of. Time the expanding circle and aim for a Perfect Dodge right before impact.

Perfect Dodge On Rhodagn's Pull Combo

Phase 1's most lethal move is the Pull followed by a Slam. The area of effect of this attack is huge, which makes running away a gamble. So, just like with his opening slam, lock onto the timing of both circles on the ground and execute a Perfect Dodge.

Interrupt the Double Swipe-Slam

After he swipes twice, Rhodagn briefly charges up, and a warning circle appears. The blast radius is small enough to simply step out of, but you can also interrupt the attack entirely by hitting him with a skill while the circle is active.

Watch Out for the Charged Dash

Rhodagn's Charged Dash combo has very little wind-up, making it easy to miss if you're stuck in melee range. There is a split-second pause between the dash and the punch, so use that window to calmly reposition yourself.

Phase 2: Larger AoEs and Fire

In Phase 2, Rhodagn incorporates fire and shockwaves into his arsenal. His attack ranges are significantly larger, so Perfect Dodging becomes crucial. Also, remember that you can survive his recurring ultimate attack by taking cover behind the summoned walls.

Hide Behind Walls to Dodge Rhodagn's Ultimate

When Rhodagn summons four pillars, he's prepping his ultimate. If you try to face-tank this to keep attacking, the two-part blast will deal Massive DMG and Knockback. Play it safe and get behind a wall.

Tips!	It is possible to survive by executing two back-to-back Perfect Dodges! This is risky, but highly recommended if you're gunning for the 120-second speed-clear achievement.

Fireballs Leave Hazardous Zones

He'll launch a barrage of fireballs that deal heavy direct damage and leave lingering hazards on the ground. However, hitting him with an interrupt skill while the warning circle is up will reduce the number of projectiles, making the attack much easier to handle.

Rhodagn's Slam Has 3 Shockwaves

The Phase 2 version of his Jump Press sends out three shockwaves upon landing. Eating all three hits will result in Massive DMG. Either step entirely out of the blast radius or Perfect Dodge into the shockwaves.

Flamethrower Variations: Sweeping and Steady

The Phase 2 flamethrower comes in two flavors: a sweeping attack that tracks your movement, and a straight-line blast that explodes. For both variations, the best defense is to chain your dodges while moving out of the danger zone.

Recommended Teams for Rhodagn

Story-Friendly Endministrator Comp

Attacker	Attacker	Inflict Vulnerable	HP Recovery
Perlica	Endministrator	Chen Qianyu	Ardelia

This Endministrator-focused team uses only the initial free roster. Ranged combat makes dodging and positioning significantly easier, so we highly recommend controlling Perlica manually.

Perlica + Wulfgard Originium Arts Comp

Attacker	Attacker	Buff + Debuff	HP Recovery
Perlica	Wulfgard	Antal	Ardelia

A solid Heat and Electric hybrid team that can be built entirely for free-to-play. Since Rhodagn fights alone, Antal's Focus passive is incredibly effective here. Your goal is to unleash Wulfgard's Enhanced Battle Skill, which can be boosted by Electrification, buffs, and debuffs the moment Rhodagn is staggered.

Laevatain Comp for RE-Crisis Agony

Attacker	Inflict Heat	Recover SP	HP Recovery
Laevatain	Wulfgard	Akekuri	Ardelia

This Laevatain-centric squad is designed to completely overwhelm the boss during her Ultimate. Keep Combustion and Corrosion applied while charging Laevatain's energy, then drop her Ultimate the second Rhodagn is Staggered to melt his HP bar.

Tips!	Note that triggering Laevatain's Ultimate will automatically swap your active control over to her, even if you were playing as Wulfgard or Ardelia.

How to Unlock Rhodagn

Fight Him in Chapter 1: Valley Fort Battle

There's a handy Teleport Point just outside the entrance where you can heal and manage your Backpack.
