Hello,

We are checking on this and will update the topic once I know more.

The skills that allow Sayha Seer to become hidden are an integral part of the class and we do not currently plan to make any changes to the associated skills.

If you believe the Sayha Seer skills are being abused by another player, please record the encounter and submit a ticket to our Customer Service team, and we will investigate each report on a case-by-case basis. Thank you!
