The following are data related to Artifact affix distribution. In summary, main affixes and initial minor affixes use a weighted distribution system, while minor affixes values and minor affix upgrades when enhanced to the next tier are distributed evenly.^[1]

Main Affix

For all artifacts of any quality:

Flower of Life

Plume of Death

Sands of Eon

Goblet of Eonothem

Circlet of Logos

Minor Affix Attribute

When rolling the initial minor affixes or adding a minor affix upon a new tier, the probabilities for getting each minor affix is dependent on the pool of available minor affixes and calculated based on each minor affix's fixed weight. Minor affixes identical to the main affix and already-existing minor affixes are omitted from the pool. Flat and percent affixes are not identical, so a Plume of Death can have ATK% as a minor affix, but not flat ATK (which is its major affix).

The probability for a specific minor affix is: ${\displaystyle {\frac {{\text{Weight}}_{\text{Minor Affix}}}{\sum {\text{Weight}}_{\text{Available Minor Affix}}}}}$

For example, if a 5-Star Plume of Death already has ATK%, Energy Recharge%, and CRIT Rate% minor affixes when it reaches level 4, the probability of obtaining CRIT DMG% as a 4^th minor affix is as follows:

${\displaystyle \begin{align} \text{Probability}_\text{CRIT DMG} &= \frac{\text{Weight}_\text{CRIT DMG}}{\text{Weight}_\text{HP + DEF + HP Percent + DEF Percent + EM + CRIT DMG}} \\ &= \frac{3}{6 + 6 + 4 + 4 + 4 + 3} \\ &= 11.\overline{1} \% \end{align}}$

Minor Affix Value

Possibilities for initial values and upgrades of minor affixes:

Value	Chance
100% of max	50%
80% of max	50%
100% of max	33% (1/3)
85% of max	33% (1/3)
70% of max	33% (1/3)
/ /
100% of max	25%
90% of max	25%
80% of max	25%
70% of max	25%

Minor Affix Slot Upgrade

When the artifact already has 4 minor affixes:

Minor Affix Slot Upgrade Times
