Genshin Impact: Three Realms Gateway Offering - Part I Guide

gamespot.com:

Genshin Impact's latest update, Three Realms Gateway Offering, kicks off with a Part I quest to unlock the more hefty Part II. Part I consists of three different trials, and each asks players to access four Flames of the High Gate in indicated locations. Below is info on how to overcome the puzzles and challenges present in Three Realms Gateway's preliminary quest.

Notice that there are familiar puzzle mechanisms from the previous Enkanomiya event: Triangular mechanisms that can be activated with elemental attacks, as well as moveable walls and gates. You can approach the four Flames in any order, but here's my recommended sequence for an easy clear.

This third one is a bit trickier than the previous two. You'll notice that regardless of Whitenight or Evernight, the third Flame is hidden behind a transparent blue barrier. Also notice that during Whitenight, three columns of light appear on top of a building. This will correspond to how you should make the walls and gates move in order to make the barrier vanish.

Follow these steps:

This one is located at a high point where the three pillars of light appear during Whitenight. To get to it, climb to a higher elevation and glide down to grab the Flame.

Once you look into a well, you'll get four pictures of each of Flames' locations. There's no puzzles here--simply follow the route indicated above for maximum efficiency.

This one, unlike the first and second trial, is a combat test. Once you light all the totems with Pyro elemental attacks (found at the base of statues) four rounds of very annoying enemies will appear. If your DPS team is even half-way decent, these should pose no problem.
