Impending Doom Shako with any useful 2nd support like Void Manipulation. Those doesn't work, beware.

Those doesn't work at all. Now that I think about this, it's so obvious and all those 2 mods ID Shako's except for something like that can modify the curses, the ID level is the only thing that matter.

Shako's wording:
"Socketed Gems are Supported By"

Other examples would be Prismatic Burst.
