Season 9 raised the ceiling for veterans: fourth-tier Seed Spheres, the Battle Core, Uruk Mountain's elite hunting and the Plaza of Trials arena. Part 2 renewed character models and pushed Rage Fighter's master options into new territory.
A high-end hunting ground with dense elite spawns, Uruk Mountain became the go-to farming zone for maxed parties of its era.
The Plaza of Trials staged wave-based combat challenges, later expanding into a Battle variant, while the Battle Core system tied rewards to competitive play.
Fourth-tier Seed Spheres extended socket crafting upward, and the Gremory Case gave players a rewards vault with timed bonus items.
Part 2 refreshed character visuals and control feel, renewed Chaos Castle into a Battle format, and expanded Fist Master skills — modernisation ahead of Season X's new class.
