When using synchronized strike my shadows beyond 5 are being replaced whenever i cast a new synchronized strike. I’m a bladedancer with the shadow master passive allocated and my normal limit is thus 5.
As i understand it the shadows from syncronized strike should theoretically allow me to go past this limit of 5.
The Shadow Master passive should only be giving one extra Shadow even if there are multiple points allocated. Along with Dark Allies adding 2 Shadows, this should bring the upper limit to 5 Shadows.
But the base number of shadows you can have is 3 (on a Marksman, for example) +1 from Bladedancer mastery +1 from Shadow Master = 5, therefore Dark Allies should take you up to 7.
