This is in regards to Mutants and Masterminds 3E Deflect.
Action: Standard • Range: Ranged • Duration: Instant • Cost: 1 point per rank
You can actively defend for characters other than yourself, deflecting or diverting attacks against them at a distance, and may be able to more effectively defend yourself, depending on your rank. See the Defend action in Action & Adventure for details. You use your Deflect rank in place of an active defense. You still add 10 to a Deflect die roll of 10 or less, for a minimum roll of 11. Deflect modifiers are limited by power level. Like a ranged attack, if you Deflect at medium range, you have a –2 circumstance modifier on your check. At long range, you have a –5 circumstance modifier. Range is Measured from you to the target of the attack you are deflecting.
I had a player invoke Deflect with the idea of staving off the next attack coming in and there arose a discussion on how to interpret who gets defended. My ultimate decision as a GM was that the spirit of the description was that you choose a single target for the Deflect, and they get the bonus, but you do not. So effectively, it lets you do a Defend action and then have the effects apply to that person until the beginning of your initiative count. As regards the picking of targets, that works for a Readied action, picking a situation and being able to preempt it.
There used to be a forum for asking the game designer, Steve Kenson, for clarifications, but that hasn't been available for a long time. There was some discussion on the official boards, but nothing that I felt directly answered my question.
