You don't seem to be stopped by the water (as if it were ground) when you would encounter a damaging fall as before. This can still be used to avoid being dis-mounted (if timed correctly) from an enemy attack.
All this does, is allow you to keep the Path of Frost after taking damage, so you don't have to re-surface and re-mount to keep going.
If you've got a level 61 Death Knight, you know what I'm talking about. If you have [Path of Frost] activated, and if you take damage, your [Path of Frost]is removed and you sink underwater. You then have to take the time to re-apply it, jump above the water, and re-mount. This is a way that (Most of the time) will prevent that situation from ever happening.
You might be thinking, "Holy shit this kid is a lazy ****", but it's easy to do, and I truthfully hate having to take the time to re-mount, so here it goes.
For this to work, you have to have an available "Frost Rune" to use during the process.
Instructions:
1. When you realize that your going to take damage, put your mouse on the [Path of Frost] skill button.
2. Right before (Less than a second) you take damage, jump with the space bar button (It might not be the space bar button if you've altered your key bindings).
3. Take the damage.
4. Right after recieving the damage (While your in the air), re-apply the [Path of Frost] skill.
5. Land your fall on your mount, and be on your way.
Your going to want to jump just before you get hit, the closer the better, this will give you more time to re-apply the spell. You have to make sure that you use PoF just after you take the damage. Timing is everything here.
Good Luck to everyone.
