If potion expires in between the two blessed blade strikes using the lvl 30 Virtue of Audacity talent, the second strike doesn’t occur.
This happens regularly if using concoction trait on charm. To reproduce:
- Drink any potion while having concoction trait on charm equipped.
- Cast blessed blade.
- Cast blessed blade again as soon as cooldown is refreshed (will be at last second of the potion’s effect).
