Clair Obscur Expedition 33 – Yellow Harvest 100% Guide

The Continent in Clair Obscur: Expedition 33 is huge, filled with many sub-regions that players can explore for new boss encounters and items. With such a massive map, it’s easy to miss out on key items that you’ll need to make your party stronger. Yellow Harvest, though accessible immediately after adding Esquie to your party, can be easy to overlook because of where it’s located.

While it is a linear area, there are paths that intertwine and can make it easy for you to lose track of where to go next. In this guide, we’ll walk you through all the items, collectibles, and boss encounters you’ll find in Yellow Harvest so that you don’t miss out on anything in Clair Obscur: Expedition 33.

All Items and Collectibles in Yellow Harvest in Clair Obscur Expedition 33

To reach Yellow Harvest, players must first recruit Esquie to their party in Clair Obscur: Expedition 33. It’s located northwest of the Hidden Gestral Arena. You’ll need to use Esquie to break rocks to reach the entrance to Yellow Harvest. Once inside, interact with the Entrance Expedition Flag to unlock the region’s first fast travel point.

Gaulteram (Weapon)

• Starting Expedition Flag: Entrance

From the Rest Point, climb the wall spikes to reach the next section. Drop down and move forward past a Gestral NPC staring at a Nevron in the distance. Eventually, you’ll reach a clearing with a large fountain. Defeat the first Gault enemy here to unlock the weapon Gaulteram

.

Colour of Lumina

• Starting Expedition Flag: Entrance

Move past the fountain area and take the left path at the fork with the grappling point. Defeat the enemy ahead and drop off the ledge to collect a Colour of Lumina

from a small ledge as marked in the image above. Drop down again, and you’ll return to the fountain area.

Harvester’s Hollow Expedition Flag

Use the grappling point after the fountain, and this time, head to the right. After picking up some Chroma on the ground, drop off the ledge to activate the Harvester’s Hollow Expedition Flag.

Death Bomb (Pictos)

• Effect: On Death, deal damage to all enemies
• Stats: Speed 43, Critical Rate 10%
• Starting Expedition Flag: Harvester’s Hollow

Pictos is found directly in front of the tent.

Expedition 38 Journal

• Starting Expedition Flag: Harvester’s Hollow

Take the nearby ramp and continue until you reach an open area. The journal lies on the ground near two fallen Expeditioners.

Pinabby (Merchant)

• Starting Expedition Flag: Harvester’s Hollow

After grabbing the Expedition 38 Journal, look for a grapple point in the top right corner instead of dropping down. It leads to the merchant Pinabby, who has a couple of items for you to buy. You can also fight this merchant similar to the one in Gestral Village to unlock a new Pictos in his stock.

Expedition 44 Journal

• Starting Expedition Flag: Harvester’s Hollow

Keep moving forward past the earlier ramp. You’ll find this journal surrounded by several Nevron carcasses.

Mime Encounter + Braid Haircut (Maelle)

Near the Expedition 44 Journal, look for a small cave on the right. Inside is a Mime enemy that you can defeat to unlock the Braid haircut for Maelle.

Young Boy NPC

• Starting Expedition Flag: Harvester’s Hollow

From the Harvester’s Hollow flag, head left and defeat the first enemy. Immediately after, use the grappling point on the left to reach the Young Boy NPC. Continue along the path and drop back down to return.

Potierim (Weapon)

• Starting Expedition Flag: Harvester’s Hollow

In the open section of the Harvester’s Hollow region, you’ll find three Jar enemies roaming around. One of them can defeat the Potierim

weapon for Lune.

Colour of Lumina

• Starting Expedition Flag: Harvester’s Hollow

In the large open area, take the central ramp to the next section. Use the grappling point to leap to a building. Then, drop from the southwestern side onto a balcony to pick up a Colour of Lumina

.

• Starting Expedition Flag: Harvester’s Hollow

After collecting the Colour of Lumina

, drop off the balcony and return to the ramp. Follow the path until you reach the Yellow Spire Wrecks Expedition Flag.

Expedition 59 Journal

• Starting Expedition Flag: Yellow Spire Wrecks

Take the left path from the Expedition Flag. The journal lies near glowing red rocks and a few fallen Expeditioners.

Glaise Boss Fight

• Starting Expedition Flag: Yellow Spire Wrecks

Glaise is the main boss of the Yellow Harvest region. You can get there by heading right from the Expedition Flag. However, you’ll want to be fully prepared before you take on the boss, as he can easily overwhelm you if you’re underleveled. Learning his parry timings will make the boss go down a lot easier. Defeating him rewards you with the Plenum

weapon for Maelle and the Energising Attack I

Pictos and 3x Polished Chroma Catalyst

.

Chromatic Orphelin Boss Fight

• Starting Expedition Flag: Yellow Spire Wrecks

After defeating Glaise, you can move forward to get to Lost Woods. But instead of continuing up the path, turn around and look behind to find a small platform you can mantle onto.

Jump up and drop down into a hidden cave. Continue moving to find three Nevrons working near a hot air balloon. Walk toward them to trigger the boss fight. Like Glaise, this is a tough battle. Defeating Chromatic Orphelin unlocks Kralim

, a new weapon for Lune, plus several Polished Chroma Catalyst

and Colour of Lumina

.

Before exiting back into Harvester’s Hollow through the second tunnel, grab the Chroma lying on the ground, a final reward to wrap up all the items and collectibles in the Yellow Harvest region of Clair Obscur: Expedition 33.
