Minor Affix Attribute
When rolling the initial minor affixes or adding a minor affix upon a new tier, the probability for each minor affix is dependent on the available pool and calculated based on fixed weight.
When upgrade a legendary artifact to level 4, the probability of obtaining a specific minor attribute/affix depends on the available pool and the fixed weights of each attribute/affix. The pool, in simple terms, is a list of attributes where each attribute has its own assigned weight—essentially its significance or rarity.
| Attribute | Weight |
|---|---|
| HP | 6 |
| ATK | 6 |
| DEF | 6 |
| HP% | 4 |
| ATK% | 4 |
| DEF% | 4 |
| Energy Recharge% | 4 |
| Elemental Mastery | 4 |
| CRIT Rate% | 3 |
| CRIT DMG% | 3 |
Formula for Minor Affix Probability
The probability for a specific minor affix is calculated as:
P(A) = Weight(A) / ∑(Weight of Available Minor Affixes)
Example Calculation
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 4th minor affix is:
P(CRIT DMG) = Weight(CRIT DMG) / (Weight(HP) + Weight(DEF) + Weight(HP%) + Weight(DEF%) + Weight(EM) + Weight(CRIT DMG)) = 3 / (6 + 6 + 4 + 4 + 4 + 3) ≈ 11.1%
