Disk Drives Stats

If you want to learn more about Disk Drives themselves, do check our other guide as here you will find only information about the main and sub-stats that you can roll on them.

Disk Drives

Main Stats

Each Disk Drive has one main stat and up to 4 sub-stats. Depending on the Disk Drive slot it fits in, the possible main stats are:

• I - Flat HP
• II - Flat ATK
• III - Flat DEF
• IV - HP%, ATK%, DEF%, CRIT Rate%, CRIT DMG%
• V - HP%, ATK%, DEF%, PEN Ratio%, Attribute Mastery
• VI - HP%, ATK%, DEF%, Anomaly Rate%, Energy Regen%, Impact%

Sub Stats

Disk Drives sub-stats are randomly generated, but they cannot be the same as the Disk Drives' main stat. The list of possible substats are:

• Flat HP
• Flat ATK
• Flat DEF
• HP%
• ATK%
• DEF%
• Crit Rate%
• Crit DMG%
• PEN (flat)
• Attribute Mastery

Each column shows a pair of values: the main stat at +0 and at +12/+15 (depending on the rarity of the Disk Drive). There are no random rolls here - you always get the same main stat value once you reach a certain enhancement level.

• Slot I
• Slot II
• Slot III
• Slot IV
• Slot V
• Slot VI

Since the sub-stat pool is the same no matter the Disk slot it fits, there's no point in splitting them. Just remember that you can't have the same main stat and sub-stat on the same item, for example if you've rolled HP% on the main stat, you won't be able to get HP% as one of the sub-stats (but you will be able to get flat HP as the game treats them as separate stats).

Sub-stats ranges

This table shows the possible sub-stats values you can get per one Enhance. This means the base sub-stats values of a Disk Drive you've just obtained will be shown here and also every time you Enhance a Disk Drive, one of the sub-stats will increase by that amount. As usual, higher rarity Disk Drive will have higher ranges for the sub-stats. Compared to Honkai: Star Rail, the sub-stats values are static - it means that if you roll a stat, it will always increase by the same static value every single time. Gone are the days of random rolls that can sour your day even if you get the stat you want, but low roll the value.

Important! If you've got a Disk Drive that rolled different values, please let us know and we will fix the data below.
