In the Tower this morning, facing opposing teams that contained Solaris, my Shade was unable to possess dead (non Solaris) heroes. I tried 4 different times, in 4 different opposing teams that contained Solaris, and nothing - no invalid target message, nothing.
After Solaris opposer, next team without Solaris, my Shade was able to posess dead opponent hero with no problem.
Can someone please explain why this happened?
I admit I am only partly familiar with Solaris' abilities.
