Essential Combat Tips
MP Management – Equip a reactor with skill cost reduction and MP recovery stats. You’ll burn through mana faster than the boss burns through health bars.
The Floor is Actually Lava – As the fight progresses, molten lava floods the arena, shrinking your combat space. The boss also drops lava pools while walking—watch your step!
Distance is Your Friend – During the nuke phase, maintain distance while breaking pillars. You can safely hug the pillars, just not the boss.
Weak Point Priority – With that absurd health pool, hitting weak points isn’t optional. Target them religiously to beat the 10-minute timer.
Critical Attacks to Watch
The boss cycles through devastating attacks that’ll wreck unprepared players. Master these patterns:
- Nuke Orb (PRIORITY): When it burrows and charges, immediately destroy the three surrounding pillars to stun and prevent arena-wide devastation
- Orbital Strike: Tracking laser that follows until impact—keep moving
- Exploding Rings: Three-wave AoE marked by red indicators. Stay on the edge and reposition between blasts
- Lava Rings: Two types—destroy expanding orb rings; grapple over contracting rings after squat animations

Best Descendants for This Fight
Hailey dominates this encounter after her recent damage buff. Her Cold Heart build exploits the fire-type boss weakness perfectly. Viessa also performs well with ice abilities. Learn more about elemental advantages in Nexon’s official guide.
Bonus Tip: Minions spawn throughout—they’re walking ammo and health dispensers. Don’t ignore them when you need resources.
Your Winning Gameplan
Practice makes perfect here. A few attempts will teach you the attack telegraph patterns better than any guide. Focus on positioning, maintain your MP pool, and remember—those weak points are your ticket to a sub-10-minute clear.

Frequently Asked Questions
Q: What’s the best way to prepare for Lava Citadel’s hard mode?
A: Prioritize a reactor with skill cost reduction and MP recovery. Build Hailey with a Cold Heart setup for maximum damage, and practice the normal mode until you can consistently break the nuke phase pillars. Strong gear matters less than mechanical execution in this fight.
Q: Can I survive the Nuke Orb ultimate without breaking the pillars?
A: Technically yes, if you stack massive HP or shields, but it’s extremely risky and inefficient. Breaking all three pillars not only prevents the explosion but stuns the boss for valuable DPS time. Always prioritize pillar destruction when you see the boss burrow.
