Genshin Impact - Three Realm Gateway Offerings Part 2, 3, And Bunkoku Engima Guide

gamespot.com:

Genshin Impact's Three Realm Gateway Offerings event is probably the most player-friendly limited event we've had to date. There's no confusing puzzles like Dante's labyrinth mazes and all the event treasure chests are marked on the map already. Here's all you need to know about the Bunkoku Enigma and the Three Realm Gateway Offerings event parts two and three.

This quick guide on Part 2 and Part 3 will cover the basics and some tips for (slightly) tricky areas. Three Realm Offerings takes players to an Enkanomiya map shrouded in a darkness called Corrosion. Using a gadget you automatically receive, the Bokuso Box, players can dispel the Corrosion around chests and enemies for rewards--including Sigils, currency used to upgrade the Box at the Statue of The Vassals.

As mentioned previously, both the new limited event resources you need to gather--Aphotium Ore and Tokoyo Legumes--as well as treasure chests, are marked clearly on the minimap, which is quite different from the Golden Archipelago limited event.

The basic play process then is to venture out into the open world--collecting minerals and plants necessary for unlocking Towers and opening chests--then going back to the tree and upgrading the Bokuso Box. You'll want to do this consistently in between the primary questline branches (unlocking the Towers) because the Corrosion level increases in new areas. Upgrading the Bokuso Box increases the amount of Corrosion you can withstand. Once you reach level 14 on the Bokuso Box, a new set of chests and challenges will sprout up on the map.

The puzzles that might give you a slight pause are the ice and water mirror ones. You turn the panels into ice by using a Cyro character and back into water by using a Pyro character.
