Hello Savior!
The ‘damage increases by 25%’ in the tooltip of Sauk Savinose Dysnai Leather Armor is currently misguided as ‘healing increases by 25%’.
The actual effect of the Armor is applied as ‘damage increases by 25%’ and the tooltip will be corrected during the scheduled maintenance next week on November 24, 2020.
Sorry for causing confusion and thank you for addressing the issue.
Thank you and have a nice day with TOS!
