Affixes

"Affixes" (also known as Bonuses and Modifiers) are the special magical properties found on items in the Diablo games.

Affix Development

There have already been changes made since the BlizzCon reveal to add the following three affixes as an example.

Here are the changes we’re considering:

We’re increasing the total number of affixes on items, including Magic (Blue), Rare (Yellow), and Legendary (Orange). This should raise the overall importance of non-Legendary affixes on your character’s overall level of power.
We are also introducing three new stats:
- Angelic Power, which increases the duration of all beneficial effects (like self-buffs or healing)
- Demonic Power, which increases the duration of all negative effects (like debuffs or damage over time)
- Ancestral Power, which increases the chance of on-hit effects (aka increased proc chance

These new stats can appear as affixes, such as +15 Angelic Power. In addition to providing the above-stated benefit, Blizzard wants these new stats to also act as prerequisites for empowering certain other affixes. If you don’t have enough of a specific power, you can still equip the item, but you may not benefit from an affix linked to that power.

These additions are an example of how Blizzard is fine-tuning the items and affixes so that players have to decide whether a particular item is best suited to your build.

We do know some of the affixes that appeared in the BlizzCon 2019 demo and these are a good indication of what to expect.
