Found this last night, didn’t have time to do voice over.
Diona has a bug that makes her Ascension 1 talent last forever, even if you exit the game and log back in.
Heres how to do it:
Use Diona E
Switch to target character (not Diona)
Force quit (Alt + F4) and restart game
You should see that your target character still has the green arrows indicating the buff is still active
There are 2 additional things with this:
You can do it on multiple characters
The buff is still active even if you switch out Diona afterwards
I should note that if you exit the game normally at anytime, the buffs will disappear
With this buff you can get up to 82% reduced Stamina Consumption
Here’s the video if you need a visual guide or just to see it in the works.
