The last event took place in Sumeru so players might also need to go to the area to interact with the NPC.

How to complete the event?

Players will be provided with an ability called “Fayz Potion” during the battles. The Fayz Potion gets fully replenished with the help of “Fayz Tinctures”, which it gains over time or when the players defeat enemies. When the Fayz Potion is full, players can click on that button to enter a “Time Dilation” mode. In this mode, the enemies will be paused and players will be equipped with a camera. You can rotate the “Viewfinder” camera angle or zoom in or out to capture as many enemy weakness points as possible during this time.

Once players have collected the Weaknesses, the Time Dilation period will be over and a “Supersense Skill” will be unleashed. The Supersense Skill releases a wave of powerful Dendro DMG that can help players obliterate their enemies. Hence, it is crucial to time the usage of the Potion properly to defeat waves of stronger enemies. If players can accumulate more than 8 Weaknesses in one go, a buffed Supersense Skill is released, dealing greater damage.
