How to Use the Bokuso Box

All Uses in Three Realms Gateway Offering

All Uses of Bokuso Box
Explore Three Realms Gateway Offering with Corrosion Complete Bokuso Box Puzzles Disperse Darkness from Enemies

Corrosion Resistance to Explore Enkanomiya

The Bokuso Box stores energy which allows traveling within the corrosion affected areas. The corrosion accumulates over time and depletes the Bokuso Box's energy.

You can use 6 Energy from the Bokuso Box at a time!

Corrosion Index and Bokuso Box

The bigger the gap of the corrosion index of the area and the corrosion resistance of the Bokuso Box, the faster the corrosion will accumulate. Higher corrosion index will also decrease characters' Physical and Elemental resistances, and lower the damage dealt.
