Yes, it's explaining how the card works. It still doesn't change the rules for movement. So, no, in theory nor in fact could you Lunge through a wall or off of elevated terrain.

From what I have read it works very similar to OoTS and that isn't a movement, it is a repositioning. OoTS does require LOF though and Lunge does not. I do agree that Lunge should not allow you to reposition on the other side of a wall or blocking terrain but I can see how someone can make that assertion from the clarification of the card text.

The question is, does repositioning a character mean that you are moving a character and hence use all the rules for movement?

Thanks for the clarification. I agree with you.

I don't know if this helps, but Zoom doesn't qualify for Lunge.

Good call! Be nasty if he did though.
