The Chromatic Hexga in Clair Obscur: Expedition 33 fight starts after you swim across to a portal past the Stone Wave Cliffs. Use Esquie’s traversal to reach the hidden beach and grapple up to the arena. There's no dialogue — it launches into combat the moment you enter.

Let’s go over what makes this fight tick and how you can survive.

• The Boss opens with a heavy shield that blocks all incoming damage. You’ll need to break this first. Multi-hit attacks like Maelle’s Fleuret Fury or Breaking Rules work great here — they strip the shield bar faster than single hits. If you’ve got leftover AP, use Free Aim shots to keep chipping away while saving SP for later.
• Once the shield drops, you’ll notice white glowing crystals on its back. This is where Free Aim comes in. Lock onto the weak spots to start doing real damage — but move quickly.
• At half health, Chromatic Hexga casts Curse on your entire party and becomes invincible again. If you don’t clean the debuff off within three turns, party members die instantly — no exceptions. Use Perfect Recovery or Healing Tints the moment Curse lands.
• Alongside Curse, it also buffs itself with Rage, letting it take two turns in a row. This is where things can spiral out of control fast.

• Go all-in with Gradient Skills and Ice-based attacks (Ice Stance if you have Lune). Fire is mostly ineffective here, so leave those spells behind. Maelle’s combos shine during this phase, especially if you've got her in an aggressive build.

Note: If you have Monoco on your expedition team, his Stalact punches deal considerable medium damage to the boss.
