Perhaps put some sort of exact range limitation on it. It just doesn't sit right with me that you could toss the thing into a warmer climate rival's home city and watch everyone freeze to death, y'know?

The Lonely God has no rivals, but I understand your point. The entire idea of the Shard is that it's the inverse of Krustaliem's powers, being most effective furthest from where he has direct control. That its range limitation. It's less effective the closest it is to where Krustaliem is the most effective, to the point of being completely useless in Glacinus itself. I figured that it was fair as an amalgamation of all three of his potential artefacts.
