The Three Realms Gateway Offering is a 40-day event that runs fromFeb. 17, 2022, to Jul 29, 2025. It’s set in Enkanomiya, the region hidden beneath Watatsumi Island. All players who have completed the following prerequisites are eligible to participate:
What is Corrosion?
Not to be mistaken for the Rifthounds' Corrosion debuff, the Three Realms Gateway’s Corrosion effect is more akin to a meter that determines how much darkness is blanketing a particular area. This affects your gameplay: you can’t easily explore areas with a Corrosion Intensity significantly higher than your Resistance level. Moreover, if the Corrosion Index is too high, you’ll experience a significant deterioration in your Physical and Elemental Resistance, as well as overall Damage.

What is Corrosion Intensity?
Corrosion Intensity is the level of darkness in an area. You can find these values in the World Map, which specifies the Intensity of the locations that you may have trouble accessing. If you enter an area with a Corrosion Intensity that’s a lot higher than your Resistance, the Bokuso Box’s lightwon’t be able to lift the darknessfrom enemies, objects, and more. Its light will alsodecrease at a moderate to fast pace, depending on how large the Corrosion discrepancy is.
What is Corrosion Resistance?
Corrosion Resistance signifies the level of Corrosion Intensity that the Bokuso Box can tolerate. It’s possible to enter areas with a higher Intensity than your Resistance, but there’s a high chance that the Box’s light won’t be strong enough to manage the darkness.
Increase your Resistance byleveling up the Bokuso Box. It starts out at six Resistance for level 1 and maxes out at 120 Resistance at level 15.
What is Corrosion Index?
The Corrosion Index can be found to the left of the mini-map. This value determineshow much yourbattle performance is affected by the Corrosion Intensity in the area. The higher the Index, the larger the penalty to your Physical Resistance, Elemental Resistance, and Damage.
So, if you venture to a place with a much higher Corrosion Intensity than yours, you may find that you’re taking more Damage and dealing less in return. Additionally, a very high Index will alsoincrease the rateby which the light of the Bokuso Box decreases over time.
