Does blizzard actually slow enemies down and by how much?
Some runes like grasping chill slow enemies down. What about the others?
My main use of blizzard is not really to damage enemy but to slow them down for poison hydra.
The tooltips doesn't say it snares at all. It says it does cold damage it doesn't say it slows enemies. If it does by how much?
To make it clear. My extensive experience shows that yes blizzard slow. I want to make sure of it. Also I want to know by how much. Does Cold Damage Slow Enemy Movement Speed Only? is related and there is no answer for that either.
All blizzards slow enemies by 30%. Grasping Chill has an additional slowing effect after the blizzard is over, by leaving ice on the ground.
Source: My own testing, since none of the books or tooltips suggest Blizzard slows enemies. You will always see "snared" come up on monsters as they are hit by the blizzard though.
