What does Illwinter (the global) do?
 

Title pretty much says it all. I'd like to know more accurately about the effects of Illwinter global enchantment since the spell description is rather vague. It implies I get some giants after some time, what kind of giants are they and how long does it take before they start appearing? Is there any other relevant effects I should know about? Is this spell generally worth casting?

Makes the world colder, adds unrest, and triggers random attacks in enemy lands (wolves and a few Niefels, if memory serves). Don't expect the Rimtursars to actually manifest, 'tho.

In my experience with this spell in Dom2, and I dont think it has changed, this spell spreads dominion and especially cold dominion. Eventually it can domkill almost all opponents too. Never saw any Giants.

Niefel Giants didn't appear in Dominions II, because the spell wasn't restricted to just Jotunheim. Caelum used to cast it a lot...
