The most important takeaway from the current test build is the dominance of Damage Over Time builds, propelled by the new Mythic items and charms, particularly the powers associated with Leoric's Crown. Conversely, the once-mighty Barbarian has seen significant nerfs, creating a new hierarchy of power. This guide breaks down the best builds for every class based on the highest Pit clears recorded on Diablo 4 Gold the PTR.

The S-Tier Powerhouse: Warlock

If you are looking for the absolute strongest class to start Season 15, look no further than the Warlock. The class has received substantial buffs, making it the undisputed king of the PTR. Almost any Warlock build that focuses on Hellfire damage is capable of dominating endgame content, clearing Pit Tier 150 with relative ease.

Blazing Scream (Top Recommendation)

This build is currently the highest climber on the leaderboards, easily reaching Pit Tier 150. It focuses on chaining Hellfire skills to clear entire screens of enemies. The core concept involves leveraging Blazing Skull and the Abodian charm set with Metamorphosis to push Demonform and Hellfire damage to their absolute limits. This is the build to play if you want to experience the season's peak power.

Apocalypse (The Reliable Heavy Hitter)

The Apocalypse build remains incredibly potent, also capable of Pit Tier 150. Its strength comes from a combination of items like the Hand of the Wall Breaker, which provides a massive 520x multiplicative damage bonus, and Moloch's Beating Flame, which stacks damage based on volatility. If you are looking for a build that has a proven track record and is now even stronger, this is a fantastic choice.

Key Items for Warlock: The build excels with Leoric's Crown and various new Mythic charms like The Eightfold Idol.

The A-Tier Contenders

These classes may not be able to reach the absolute heights of the Warlock, but they are more than capable of clearing the game's most difficult content.

Rogue: Penetrating Shot

The Rogue's best build on the PTR is the Penetrating Shot build, which has surpassed the previously dominant Death Trap. It has been recorded clearing Pit Tier 145. The build ramps up massive damage by maintaining its distance and avoiding hits, and it typically utilizes Poison Imbuement to great effect.

Key Items: Leoric's Crown is once again a core component, paired with Eaglehorn, Squirt's Blouse, and the Blood-Mad Idol charm for extra juice.

Barbarian: Whirlwind

Despite suffering significant nerfs, particularly to Ramaladni's Magnum Opus, which now burns 10 percent of your Fury per second instead of a flat amount, and a reduction to their core stat's damage coefficient, the Whirlwind Barbarian remains incredibly resilient. It has achieved a Pit Tier of 141. The build still uses its classic shout toolkit and The Grandfather to spin through enemies while maintaining high survivability.

Key Items: Leoric's Crown is still used, along with The Grandfather, Gohr's Devastating Grips, and the Ring of Starless Skies.

The B-Tier and Niche Builds

These builds are either slightly behind the top tiers, have more specific requirements, or represent new and exciting playstyles that are just emerging.

Sorcerer: Ring of Fire / Pyromancy

The Sorcerer's strongest build is a classic Pyromancy setup, typically utilizing the Ring of Fire and skills like Hydra and Meteor. It has been recorded at Pit Tier 137. While this build has received significant damage boosts from the new seasonal mechanics, it is considered a known quantity with no major playstyle changes.

Spiritborn: Poison Counterswarm

The Spiritborn remains competitive with its Poison Counterswarm build, also hitting Pit Tier 137 on the PTR. This is notable because the build achieves this high clear despite using fewer Unique items, highlighting the inherent strength of its core mechanics.

Necromancer: Bone Spirit (DOT)

The Necromancer's top build on the PTR is a new take on Bone Spirit that converts the skill into a Damage Over Time build. By leveraging the new Leoric's Crown to give up crit chance for a massive 130x damage multiplier, this build hits very hard. It has been seen clearing around Pit Tier 138. The build utilizes the Diamond Mine charm set to further augment its damage.

Druid: Rabies (A Surprising Comeback)

In a shocking turn of events, the Druid's best PTR build is the first-ever top-tier Rabies build, reaching Pit Tier 137. This build focuses entirely on poison damage and damage over time, making excellent use of the new mechanics that benefit DOT effects. It leverages items like the Arox Needle to apply Deadly Strike, a new variant of critical strike that works with DOTs.

Key Items: Den Mother charm set for damage reduction and Might of the Ursine are key, along with the powerful Blood-Mad Idol charm.

Paladin: Shield of Retribution / Origin

Unfortunately for fans of the new class, the Paladin is currently in last place. Its top builds are the Shield of Retribution and Origin builds, with the highest recorded Pit clears being only 134 and 135. While it remains a durable class, its damage output is significantly lower than its peers on the PTR. The main issue seems to be its inability to compete with the massive multipliers that other classes are enjoying.

Key Items: The Shield of Retribution build focuses heavily on stacking Resolve and Auras to augment its Thorns damage, utilizing items like Ward of the White Dove. The Origin build, on the other hand, revolves around the Judgement skill and its spread mechanics.

Final Thoughts

Based on the PTR, Season 15 will be the season of the Warlock. The class is incredibly potent, with multiple builds capable of clearing the hardest content. The new Leoric's Crown, along with the buffs to DOT mechanics, has completely reshaped the meta. While the other classes can still perform well, they are playing a different game compared to the Warlock's raw power. Keep in mind that these are PTR results, and Blizzard may implement further changes before the official Season 15 launch.
