Chugging the "Fayz Potion" in Domains allows your mind to be so extremely sharp that you can observe a fantastic scene where time almost stops amid combat. Take this opportunity to observe your opponents closely and capture their weaknesses as exposed mid-battle. Take them down this way to help the groaning Sumeru researcher finish his project.
1. Help Jami with his research during the event to obtain Fayz Potion and unlock the Fayz Experiment Facility.
2. After entering the Fayz Experiment Facility, you can defeat opponents in combat to obtain Fayz Tinctures that will accumulate up to a certain point where they can be used to enter Time Dilation mode. You can accumulate up to 3 uses of the Fayz Potion at any one time.
3. After you use the Fayz Potion and enter Time Dilation mode, you can use your View finder to spot your opponents' Weaknesses and use a Supersense Skill. When you have spotted over 8 such Weaknesses, you can unleash a buffed Supersense Skill.
4. Different opponents will have different numbers of Weaknesses. You will find folden Critical Weaknesses in some opponents. Spotting 1 such Critical Weakness is equal to spotting 2 ordinary Weaknesses. The former allows you to obtain a buffed Supersense Skill more efficiently. If you leave Time Dilation mode without spotting any Weaknesses, you will not expend any Fayz Potions.
5. Elite opponents will be present during these challenges, and they will constantly summon Attendants to aid them until they are defeated.
