Effect Hit Rate

Effect Hit Rate is one of the stats in Honkai: Star Rail, used by both characters and enemies. It increases the probability of attacks inflicting debuffs on a target.

${\displaystyle \begin{align} \text{Real Chance} ={} & \text{Base Chance} \\ & \times (1 + \text{Effect Hit Rate}_\text{Attacker}) \\ & \times (1 - \text{Effect RES}_\text{Target}) \\ & \times (1 - \text{Debuff RES}_\text{Target}) \end{align}}$
