Currently, as I am reading the effects from Synchronized Strike, the area of effect increases should also affect the shadows’ attacks. Thus letting the shadows also hit the main target if the AOE skillpoints are sufficient. However, as shown in the video here: Last Epoch 0.9c, Synchronized Strike - Area increase bug - YouTube
No matter how many points you put in the “growing darkness” skill, you cannot reach the target at all. I do believe that the skill “Shadow Infusion” is working semi-properly.
Thanks!
