Rogue — Shadow Trap & Multi-Arrow Builds
Rogues benefit significantly from Diablo 4 Items the PTR changes, especially builds centered on Shadow Traps and rapid-fire Multi-Arrow attacks enhanced by Horadric Powers.

Why it's strong: The new Horadric Infusions that amplify shadow damage and stack debuffs pair perfectly with Rogue crit mechanics. This allows for high burst damage and excellent crowd control, while maintaining the class's signature agility and evasiveness.

4. Necromancer — Summoner Builds with Bone Spirit Catalysts
While some Necromancer builds struggle (more on that later), summoner-focused builds using Bone Spirit Catalysts have found new life in the PTR.

Why it's strong: Horadric Powers that enhance summons' damage and survivability help Necromancer minions shine in both solo and group play. When combined with the right Infusions and Arcana, this build can control the battlefield effectively.

Summary
The Sorcerer, Barbarian, and Rogue stand out as the clear winners in the Season 9 PTR meta, each leveraging Horadric Powers to push damage, utility, and survivability to new heights. Players willing to experiment with buy Diablo IV Items these builds will likely find themselves ahead of the curve when the full season launches.
