Damn, it's possible. I had all this army in loose, so i'm not sure from what blister they come.
But i'm certain i don't have the guy with the sphere.
Note that we already know the characters blisters changed for elves, kislev and probably dwarves. I would not be astonished it's the same for arbabian.
It would be interestinf to try to reference all the figs from the characters, for all armies. To be able to established what was the different variation in those sets.
