Red Orb (Sphere of Prohibition)

The Red Orb is quite a frightening artifact, as it can indeed be used to win in the late game by blocking the opponent and preventing potential 2k damage from the explosion, or even more. On the other hand, many will start playing exclusively as mages because those same 2k explosions are even more powerful. I voted to ban the Orb, but in principle, I haven't encountered a situation where the Red Orb decided the outcome of the game...
