As a Blade Dancer, my maximum number of shadows is currently 4.
When I use Synchronized strike with Dark Allies allocated, which states that the two extra shadows it provides can exceed the normal maximum number of shadows, I am still ending up with 4 total shadows in spite of already having 4 shadows out before using the skill.
The +2 shadows part does work, as I get 4 total shadows if I use the skill by itself. It just isn’t going over the max as the node suggests.
Thanks!
