Clair Obscur is located in the Tainted Lumiere section of The Monolith, where it will be fought as an optional boss.
From the main road, move forward but head leftwards until a grapple point is visible. Continue heading left until a flight of stairs is seen across another grapple point. The boss will be located above the stair platform.

Quickest way to deal with Clair Obscur is by using high damage area attacks such as Elemental Genesis to strike the boss and its supporting opposition.
Do note that Clair Obscur's minions, Clair and Obscur are immune to Light and Dark damage respectively so area attacks such as Phantom Stars may have reduced effectiveness.

Clair Obscur has two attack patterns with long windups which may bait the player into parrying early, taking damage in the process.
The first of these feature a two-hit long wind-up swing, wait for the sword to light up twice then wait for the drop to parry or dodge the attack. The second attack involves a delayed Gradient Attack which the player should counter to avoid massive damage.

To make the fight easier, it is always advised to take out Clair and Obscur first by either committing to elemental area attacks to prevent them from supporting Clair Obscur and attacking the player's party.
Reducing the number of opponents in the fight will help the party deal more damage to the main boss.
