Honkai: Star Rail’s battle system is simple in theory, but beginners will often struggle to defeat common enemies. A turn-based system means you’ll need to pay closer attention to each character’s stat values and strategically calibrate them to be the most efficient in battle—a challenge we’re always up for (but not everyone is). So we’re here to help you better understand some of the key terms.
DON'T IGNORE THESE 4 STATS! Speed, Break Effect, Hit Rate, ERR Explained! Honkai: Star Rail GUIDE
One of the more elusive stats in the game is Effect Hit Rate. Here’s everything you need to know about it.
Effect Hit Rate is a stat that increases the chance of your character inflicting debuffs on an enemy. "Debuff" doesn't just mean stat debuffs in Honkai: Star Rail. They also apply to status effects like Freeze, Shock, and Imprisonment. You can view your character's Effect Hit Rate by going to Details and clicking More Stats.
Most skills can only apply debuffs at a low base chance. You can increase the chance of successfully debuffing enemies by increasing the caster's Effect Hit Rate.
