In the Public Test Realm for Patch 1.4.0 of Diablo 4, countless items, skills, and stats were heavily altered to prepare the game for its fourth Season, as well as to pave the way for the upcoming Vessel of Hatred expansion.
In addition to many of these changes, Implicit Affixes on Weapons have been adjusted as well. These are the fixed Affixes that are tied to the Weapon Type that cannot be altered, such as Vulnerable Damage on Crossbows and Critical Strike Damage on Swords.
Many of these Affixes have been reduced significantly, and while it hurts to lose damage output from a change like this, it is a necessary change. Reducing these values along with other changes in Itemization will go a long way toward reducing the bloated damage values that affect the game negatively.
By allowing players to deal millions upon millions of damage in a single hit, the sense of scale and player power is lost. On top of that, balancing gameplay becomes much more challenging — thus, it's only natural that Implicit Affixes receive some tweaks at the same time as the rest of the Itemization rework.
