OW describes the "Zeroing Effect" for Begginers

[Psycho]

Freezing Mists is evil. I had my huge sacred yavana army reduced to nothing in only a few castings by Ctis's W9 A-something pretender when storming the capital.

[WraithLord]

Psycho, can you please give more details re. this battle and freezing mists effect. like:
What was the temperature?
Was it under quagmire?
Other globals?
How much damage did the mists do, max, avg (your impression of course)?
