The upcoming patch has been datamined by Wowhead ahead of its release. The newly leaked findings suggest that Season 9 will introduce dozens of changes, including tweaks for every Diablo 4 class. Quantity-wise, the Sorcerer class is leading the patch with 14 skill changes. These include a buff to Spark, whose four bolts will now deal 25% damage each, up from 12%. The arcing lightning of Arc Lash is receiving a comparable increase, with its damage rising from 42% to 80%. Similarly, the damage-over-time effects of Fire Bolt and Firewall have been boosted to 90% and 300%, respectively.

Diablo 4 Season 9 PTR Includes 6 Barbarian Skill Buffs

On the other end of the quantity spectrum is Diablo 4's Barbarian class, which will only receive half a dozen skill changes as part of the upcoming PTR experience. Among them is a major enhancement to Bash, whose damage has been raised from 33% to 90%, with an identical tweak also planned for Lunging Strike. The datamined details also include a Flay buff, increasing its Bleeding effect damage from 48% to 115%. Likewise, each pair of Frenzy-induced hits will now inflict 70% damage, up from 30%. Hammer of the Ancients will see a modest damage increase, going from 98% to 110%. Lastly, Leap will now deal 77% damage instead of 55%, while its knockback effect will be replaced by a slowing one that reduces enemy movement speed by 70% for five seconds.

The Season 9 PTR update is also set to introduce some changes to the Diablo 4 Aspects. For example, the Necromancer's Blighted Aspect will now reward consecutive hits with the Shadowblight Key Passive with a 15–25% damage increase for each attack, resetting after six seconds from the first hit. Previously, this Aspect gave a larger (35–55%) damage increase, but only activated after hitting enemies ten times.
