Patch 1.4.0 (2005-05-05): An error message is now displayed if you try to use Blink on boats and zeppelins.

Blinking will not spill you over a cliff or out a window, so if your Blink would have you end up over a drop off, you'll stop at the edge or - if you're at the edge or there is no edge - you won't move. There's a little trick here: when you're in midair (falling only; a normal jump is not "midair"), this effectively teleports you back up towards where you left solid ground. If cast half a second before impact, you are immune to the falling damage. You can take advantage of this when leaping off very high cliffs and blinking just before you hit the ground. Practice makes perfect! You'll take little to no damage if done right.

With this spell, mages are the only class that can run underwater. Just swim all the way to the floor and blink with auto run on. You will keep running (and moving quickly) as long as you don't turn. Very useful for underwater quests.

Try to use it during the fall. If you do it properly it may happen that the move to the initial location of use.

Blink in der Luft scheint so zu funktionieren wie die Kommentare es beschreiben.

Bzgl Transports such ich noch Quellen.
