You can use Bastian's Special on the Attack spoke? I thought Specials (even Special attacks) had to be used on the Special spoke. Or are you saying that all attacks (not just ones on the Attack spoke) can use the 2:1 boost that's on the Attack spoke?
You're correct that one must be in Special (obviously) to use Special and we should have chosen better wording to make it more clear earlier. HOwever, I'll confirm that Special actions can only be used when one is at Special spoke.
Similarly 2:1 transfer ratio to AP bonuses is only applicable when in Attack spoke.
All effects of Wheel are applicable only when you're in that spoke.
