Shield

This article is about the combat mechanic. For the item, see Shield (Item).

Shield
Type	Combat

Shields are a combat mechanic in Honkai: Star Rail. They are buffs applied to characters that will absorb DMG taken in place of HP.

$\begin{align} \text{Shield Value} = {} & (\text{Stat} \times \text{Stat Scaling} \% + \text{Additive Shield Bonus}) \\& \times (1 + \text{Shield Bonus} \%) \end{align}$

The remaining shield value of a character is displayed in the character menu while in combat, alongside HP and Energy.

If an instance of DMG exceeds a shield's remaining value, the portion that the shield fails to absorb will overflow and be dealt to the character.

Shield Stacking

If multiple shields are applied to the same character, they will not stack, and the effective shield value of the character is equal to that of the shield with the highest value. When taking DMG, all applied shields will absorb the full amount of DMG simultaneously. A lower-value shield can break in the background while a higher-value shield remains.

If a background shield breaks, its corresponding shield status will disappear, alongside any additional effects that the status may have provided, such as the aggro increase from March 7th's shield.
