How To Defeat The Lampmaster In Expedition 33
The Lampmaster, the final boss of Expedition 33 Act 1, is encountered in two different phases, making the battle quite challenging.
In the first phase, bosses use light-based projectiles, dark explosions, and powerful lamp attacks, which you can easily parry using the Parry Button.

Once you battle against the Lampmaters for a few minutes and bring their health down, you will transition into a cutscene leading to the boss’s second phase.
During the second phase, the boss use lamp trail, if you fail the trial , you will have to take one heavy AoE attack.
So to succeed in the Lamp trails, you need to hit the lamp when it says “the lamp emits a green glow.”

Once you have successfully completed the lamp trial several times, the boss will attack you with new flying combo moves and light waves.
To defend against the attacks, you can use Anti-Light Items like Lumina Shields or similar gear to help mitigate light-based damage.
Once you defeat the boss in both phases, you will receive significant XP, key items like the Shape of Life, and the At Death’s Door Pictos.
