Q14

Can Combat Challenge and Opportunity Attacks be used with Dream Walker's Dream Form? (note- I know that the answer to the latter is "no" prior to the printing of Opportunity Attack as an actual power, but it appears that way in the RC).

You can use powers as if you were there. You are not actually there. i.e. you are not adjacent to the target.

Speaking sadly as someone who played this build and could have easily swapped out for a couple of obvious choices...
