Hey.

So, dp053b Whizzer has Improved Movement: Ignores Elevated Terrain, Ignores Water Terrain, Ignores Blocking Terrain, Ignores Characters.

Let's say an opposing character goes to the corner of the map and then use the Wall construct to block himself.

Can Whizzer use HSS to hit the enemy while passing through one of the blocking markers?

I think since HSS attack is while you move, and you ignore blocking for movement purposes, Whizzer could hit the enemy. If it was Charge he wouldn't, though, because he can't legally end the movement in a blocking terrain. But I really need confirmation.

Thanks.

No. Whizzer must be able to stop in the square in order to make an attack from it. And since the squares are blocking terrain he cannot stop there and thus not make an attack from there.

Hypersonic Speed

Ouch. Good wording. Thanks, mate!
