How to Beat Lampmaster in Clair Obscur: Expedition 33

Struggling with the Lampmaster in Clair Obscur: Expedition 33? Here’s how to beat this creepy boss, handle its lamp mechanics, and survive both phases of the fight.
Clair Obscur: Expedition 33 – How to Beat the Lampmaster at Stone Wave Cliffs
Your mission in Stone Wave Cliffs is pretty straightforward: find Florrie, the magical rock that helps Esquie swim, and cross the massive body of water blocking your path. But of course, nothing in Clair Obscur: Expedition 33 is that simple — there’s always a boss waiting to ruin your day.
At the end of this area, you’ll come face to face with one of the game’s more unsettling enemies: the Lampmaster. It’s creepy, it’s dangerous, and it has some nasty tricks up its sleeve. But once you understand how its lamp mechanic works, the fight becomes way more manageable.
Let’s break down how to survive and win this fight — both phases included.
🪔 Lampmaster Phase One: Light, Debuffs, and Fire
You’ll run into the Lampmaster after making your way through a tunnel where lamps light up as you pass. Once you reach the end, a cutscene plays, and the fight kicks off.

🧠 Key Mechanics in Phase One:
- Exhaustion Debuff: Many of Lampmaster’s attacks inflict Exhausted, which blocks AP gain. Thankfully, this wears off at the end of the affected character’s turn.
- Lamp Projectiles: The boss puts out surrounding lamps, and they’ll fire projectiles at your party.
- You can dodge, parry, or better yet, shoot the lamps during your turn to stop them from firing altogether.
- You can dodge, parry, or better yet, shoot the lamps during your turn to stop them from firing altogether.
- Jump Attack: When the Lampmaster leaps into the air, get ready to dodge — this hits hard.
- Weakness to Fire: Lampmaster is vulnerable to fire damage. Stack burn effects early to get consistent damage over time.
Survive this phase while managing the lamp projectiles and debuffs, and you’ll push the Lampmaster to its final 10%.

🔥 Phase Two: Rituals, Lamp Puzzles & Silence
Once the Lampmaster drops below 10% health, you’ll trigger another cutscene, and phase two begins in a different arena.
This phase adds a bunch of new moves — and they can get pretty intense.

⚔️ New Moves to Watch For:
- Arm Combo Attack: The Lampmaster starts swinging both arms in a combo. Timing your dodges or parries is key here — it deals a ton of damage if it connects.
- Lamp Ritual Attack:
- You’ll see the message: “Lampmaster performs a strange ritual with its lamps.”
- Lamps will flash in a specific order — remember it!
- During your turn, shoot the lamps in that same order. If you mess it up, the boss unleashes a huge AOE attack.
- Nail it, and you cancel the ritual completely.
- You’ll see the message: “Lampmaster performs a strange ritual with its lamps.”
- Ball of Light Attack: The boss throws a glowing orb at your party. Jump over it or your entire team gets silenced for one turn (no skills allowed).
- Flying Combo Attack: This fast-paced attack can overwhelm you if you’re not careful. Keep moving and parry when you can.

✅ Tips for Winning the Fight:
- Equip fire-based abilities or weapons for extra damage.
- Keep a close eye on your debuffs. Exhausted and Silence only last a turn, but they can screw you over if you’re not prepared.
- Watch the lamps carefully during the ritual and practice the shooting order.
- Use Restore AP or Status Cure items between phases if needed.

Defeating the Lampmaster isn’t just about brute force — it’s about paying attention to the environment, reading attack patterns, and reacting quickly. Once you get into the rhythm of dodging attacks and controlling the lamps, this fight becomes way more manageable.
After taking it down, you’ll be able to continue your journey and finally meet Florrie, unlocking the ability to cross water and move forward in the story.
