Ninja run and flashbacks
I don't know about AT powers only, but I can tell you Ninja Run is disabled if you select No Travel Powers - just recently (as in yesterday) completed a Flashback with No Travel Powers selected, and Ninja Run was unavailable the entire time.
M.A. Arcs
Intended for high level play: The Primus Trilogy (Arc #s 10931, 283821, 283825), "Freakshow U" (Arc #189073), Purification (Arc #352381, Dev's Choice!

Thanks for the quick answers.
On a side note;DAMN LL I need to put you on speed dial your always answering my questions.
Can it be used during the flashbacks?Especially when you do "no travel powers" and "AT powers only". I know you can use sprint but,is NR suppressed?
