How to Defeat the Big Head in Clair Obscur: Expedition 33 ?
This fight is a endurance test pure. The Big Head follows one after another jumping attacks that deal heavy damage, and then she dies on her own after bouncing too many times. Your only goal: hold out until the end, without wasting your turns attacking her.
This type of combat is rare among the bosss of Clair Obscur: Expedition 33, a Turn-based RPG released in 2025. Keep these two tips in mind throughout the fight:
- Dodge attacks stir-fried. You can also block them, but dodging is still the safer option to avoid losing a team member.
- Prioritize caregiving skills. The rebounds hit hard, so a support character makes all the difference in bouncing back after each wave of damage.
For the composition, Lune is an excellent choice thanks to its user-friendly kit Care and Regeneration : His healing abilities and the ability to resurrect an ally help you stay in the fight longer. Pair him with agile characters to increase your dodge rate.
We have to hang in there until the Big Head has finished his run more than 20 jumps in a single round. The exact number may vary slightly from game to game, but the idea remains the same: focus solely on surviving.
Tip: take Monoco on your team. This is the requirement for unlocking its Big Head ability after the battle.
