There is an invisible wall here, anyone can get on it by just hopping off the top.
Nice try though.
If this work iam gonna rep you
It's not a noclip, it's a invisible block you can walk on, it's exploration at best but it's useless because the area is so small.

There is a forum post about it from 11/30/2010
This seems to be exploration, as it doesnt provide a benefit over other players... unless i've completely misunderstood somehting.
I think bonsemexasefe does a good job of explaining what should happen to the OP.
-Anyway, it's not no clip, it's just an invisible wall.
-There's a few of these spots throughout the game, all useless.
-Also don't see why this would be "mage only", it has nothing to do with Ice Block.
