Uh, every tia can do the wall infinite at an angle. ._.
Its just that no one does it because its looked down upon, but tias use to do it all the time in pvp when tias first came out. And there's nothing fancy about it too, you just press AASS over and over again.
Also, tias still use it all the time in stage, like Lache. Just wall infinite him till he dies. Also tias use it to kill scarecrows.
