This week Composing on the official blog, lead systems designer David Kim discussed a pretty massive change to Ancient items. They were introduced as a type of thing modifier, an improved version of an present item with values to most of the affixes in Diablo 4 Gold. These Ancient items are being removed from Diablo 4 and will be substituted with something.
What Blizzard is proposing is to replace Historical items using a sort of thing, which remains unnamed. This item will have a single arbitrary affix which can be applied to any item and is only going to fall from monsters in the late endgame.
Without adding more energy to endgame items the idea is to present methods of play. The problem with things that are Ancient was that they became a boring grind just to upgrade regular products. The rewards weren't tasked and exceptional players to an infinite grind to keep adding power multipliers. Gamers have asked diablo 4 to not follow suit. The sequel needs a better incentive to commit time. Blizzard considers that the consumable item is an excellent match in that respect.
Where affixes are concerned, Blizzard has verified some fresh ones for Diablo 4 too. There is Demonic Power that increases the duration of debuffs and damage with time. There is Angelic Power that increases the length of fans and recovery. There is also Ancestral Electricity that increases the proc chance for on-hit consequences. Blizzard is also currently considering to flip all three stats into requirements for affixes in Diablo 4.
Previously, Blizzard revealed that that the development of diablo 4 duriel mats is undecided between a finite and boundless leveling system. There are pros and cons to each since it eventually overshadows the power given by other 29, but generally, an unlimited leveling platform becomes worse with time.
