If Giants existed in BC times...

The problem with chill aura is probably that it scales very good with cold Dominion. When Niefels attacked my Lanka in recent SP, for example, aura was closer to 3 iirc. So your own strong (hot) Dominion provides fair protection. At the same time, Ice Devils would probably have to operate in more temperate climate than Niefels. I am not sure whether their aura scales with temperature less than with Niefel. If so, it should be fixed, but probably main effect is due to Dominion difference...
