Figment 2: Creed Valley

The Jester will first introduce themselves in Conviction Lane, but you won't actually fight them until the end of the stage. Once you’ve defeated them, a short cutscene will play out of everyone heading to Moral Heights. When you arrive there, the trophy will unlock.

The fight will be short and straight to the point. The Jester will create rings and lines of jester orbs that will rotate around them (in both directions). Either run with them (if there are no openings in the line) or dodge them (you can't roll through these) until the center ring of orbs around the Jester opens up, making them vulnerable. Attack them when they're in this state. Repeat this process a few times until the Jester goes down. The trophy will unlock once they do.
