As the topic title says:
On the stab/second attack of Blessed Blade with the Level 30 Talent Virtue of Audacity equipped, the ability cooldown is reset.
I assume that’s unintentional.
It’s very easy reproducable (probably even in the keep) by using a concentration potion and then using the ability.
It’s very easy to see because it resets about 15% or so of the cooldown bar, while under the effect of the concentration potion.
This also means you actually need about 15% longer between two ability uses.
This issue occurs consistently 100% of the time for me.
