Three Realms Gateway Offering Map Corrosion

Map Corrosion Intensity Explanation

High Corrosion Intensity Increases Corrosion Buildup

Genshin - Three Realms Gateway Map Corrosion
Each section of the map has a different level of corrosion. If your Bokuso Box has a lower resistance level compared to the intensity of the area, your character's Corrosion Index will increase.

How to Remove Map Corrosion

Raise Corrosion Resistance Level

By raising your Corrosion Resistance at the Statue of the Vassals, the Corrosion Intensity at different parts of the map will disappear! This will let you have an easier time exploring different sections of the map while taking your time.

Three Realms Gateway Offering Corrosion Index

Corrosion Index Explanation

Faster Index Buildup with Low Resistance and High Intensity

Genshin - Three Realms Gateway Corrosion Index Explanation
The difference between the Corrosion Intensity and your Corrosion Resistance determines how fast the Corrosion Index increases. A Bokuso Box with 6 Resistance Points will increase its Corrosion Index faster in an area with 118 Corrosion Intensity compared to one with 15!

Corrosion Exposure Effects

Lower Damage

Corrosion Index 10
Corrosion Index 100

The higher the Corrosion Index level is, the lower the damage of characters becomes. It may prove difficult unlocking the Towers of the Void because of this, especially if you need to beat Shadowy Husks!

Increases Damage Taken

Having a higher Corrosion level will also reduce your character's Physical and Elemental Resistance. Unless you're good at dodging, consider upgrading your Bokuso Box!

Drains Bokuso Box Energy

Genshin - Three Realms Gateway Reset Bokuso Box Energy Drain
