Would some one please clarify what is meant by
OUTWIT once during your turn ( BUT NOT DURING ANOTHER ACTION )
thanks

Exactly what it says. You can use Outwit at any time during your turn, but not in the middle of another action. Say, you have Flash with Outwit. Flash can use his Outwit before he runs and attacks with HSS, after he is done using HSS, but not while he is using HSS.

Thanks for the clarification.
