How to Play Fayz Trials Hypothesis

3.7 Fayz Trials Rerun Event Guide

Use Trial Characters in Event Domain

You may only use the Trial Characters provided in the event during the challenge. Like in the initial Fayz Trials event, these trial characters are pre-built and their equipment cannot be changed.

Consume Fayz Potions to Enter Time Dilation

Time Dilation can be activated by consuming Fayz Potions. Time Dilation stops time and enters a mode that looks as if you were using a Kamera or Nahida's Elemental Skill.

During Time Dilation, enemy weaknesses in the form of blue orbs will appear and can be captured. Capture as much weaknesses as possible in a single Time Dilation to use Supersense Skill and gain a higher score!

Collect Faze Tinctures by Defeating Opponents

Faze Tinctures are required to be able to consume Fayz Potions. You can acquire Faze Tinctures by defeating opponents in battle.

Once enough Faze Tinctures have accumulated, drink a Fayz Potion and capture the enemies' weaknesses!

Use Supersense Skill

After collecting enough weaknesses, you can use the Supersense Skill to deal greater DMG, earn higher scores, and gain more Faze Tinctures!

Move the Camera Around to Capture Weaknesses

It's best to group the enemies together for easier capturing, but you can still move your camera view around while capturing weaknesses to get them all in the frame!
