Before the event, the Swordplay ability read 12.75% when I have 4 Crusader with Swordplay buff ability in the formation and the 75% Increase Swordplay item. The math is as following:

5% + 5%*20%*4 + 5%*75% = 5% + 4% + 3.75% = 12.75%

But after the event, with the same situation, the Swordplay ability only read 9%. The 3.75% increase effect from the item has disappeared:

At first, I thought it is just a visual bug, but with some math, I confirmed that the increase is only 9% of the surrounding dps.

I have 915% trinket click dmg. So 9%*10.15 = 91.35%. My main dps from Turkey and Hermit is 94.1s. As you can see, 94.1*91.35% = 85.96 ~ 86.0 click damage. This confirmed the bug.

Please fix this problem ASAP.

Thank you.
