The Three Realms Gateway Offering is a 40-day event that runs from Feb. 17, 2022, to Mar. 30, 2022. Within this limited-time version of Enkanomiya, you can play through an array of new puzzles unique to the Three Realms Gateway Offering.
In the west of the region, where The Narrows would normally be, you'll find an Electro Monument puzzle that will reward you with three Exquisite Chests upon solving. Start by heading to the area circled in the image below.
Your goal is to unlock the two sealed Monuments. To do so, you must complete two Time Trial Challenges within the area. On the left, you'll find a particle collection Challenge, and on the right, you'll find a barrel-shooting Challenge. You can complete them in any order!
- Collection Challenge: collect eight Electro Particles within 90 seconds.
- Barrel-shooting Challenge: blow up five Exploding Barrels within 45 seconds.
Successfully completing each Challenge will grant you an Exquisite Chest. If you fail to complete them, you can try again an unlimited number of times. Once both are done, the Electro Monuments will unlock, and you can activate them using an Electro Attack.
You'll be rewarded with an Exquisite Chest, and the entrance to the library in front of the Monuments will open. Make sure to head inside to complete another Time-Trial Challenge for another Chest and loot three Damaged Stone Slates for The Bunkoku Enigma Event Quest.
