If you’re playing Clair Obscur: Expedition 33 and just unlocked Esquie’s swim ability, you’re probably swimming all over the place. While swimming, you might see some bright blue spots in the water. If you try to click on them, the game says you need the underwater ability for Esia. This guide will walk you through the steps to unlock Esia’s underwater swimming ability in Clair Obscur: Expedition 33.
Step 1: Talk to Esquie at Camp
To unlock Esquie’s underwater ability, you’ll need to build a stronger friendship with him. This is done by speaking with him regularly whenever you set up camp and choosing to spend time with him whenever the game presents the option. Continue these interactions until your relationship with Esquie reaches level 5.

Step 2: Find the Special Rock
Once your friendship with Esquie reaches a high enough level, he will begin talking about a special rock named Uri that allows him to swim underwater. He mentions that the rock is with his friend Francois.
This conversation leads to a visit to the cave, where, after a brief discussion and a small fight, Francois agrees to give you the rock that can swim underwater.

Finally, return to the camp to obtain Underwater Ability for Esquie.
