Vulnerability
Last updated 2026-09-10
Vulnerability, also known as DMG Taken, is a hidden stat in Honkai: Star Rail that multiplicatively increases DMG taken by a target.
Vulnerability may apply to all DMG, a specific element, or DoTs. Different sources of Vulnerability stack additively.
Vulnerability can be modified by certain character abilities as well as special buffs such as those in the Simulated Universe. Although the in-game wording for related effects is inconsistent, effects described to "increase DMG taken/received" generally modify the Vulnerability stat.
