Expatriette incapacitated ability #3

(Alternate thread title:  Even Dead, Ex-Patriette Never Runs Out Of Bullets.)

It's possible that the RC/IR reprint is about to render this question moot, but for now at least I still need to know.  Expat's third incap ability reads "Select a hero.  The next time that hero uses a power, that power also deals 1 projectile damage to 1 target".  I seem to recall reading somewhere around here that Wraith's "Stealth" power keeps stacking as long as it goes unused - if she Stealths, takes no damage, and Stealths again, then gets hit with damage, that damage will be reduced by 4.  Does this Expat ability also stack?  Can a hero sit there not using powers for several turns, but collecting a large number of 1-damage shots, which all go off at once whenever they finally do?  (I'm assuming that they remain discrete 1-damage increments and don't combine to overcome DR, but by the same token, they would multiply bonuses...if you've also got a dead Young Legacy in the party, that could make for one apocalyptic power use, after many, many turns of doing nothing other than drawing cards.  And with Nightmist in particular, doing nothing other than drawing cards is an immensely viable strategy, even if she doesn't have Mist Form or The Amulet in play.)

Yes.

One of my favorite incap abilities.  I love the way the two RC heroes interact, esp. with their incap abilities.

It was how my group beat The Dreamer once in playtesting.  Visionary was the last hero left.  Afer hiding in her TK Cocoon for a number of turns, she got a bunch of 1 damage instances from Expat, damage buffed by two or three by other effects I can't remember, and destroyed her younger self's horde of nightmares for the win!

Neat catch!
