You're not missing much. Over in Iron Man, he gave her those rings as a gift, and then later in the issue, they both fire at a Stark Sentinel and destroy it using the same blue-white colored energy. So presumably, it is the same as Iron Man's repulsor blast.
I don't know why I keep hoping Duggan will do something different, but all his issues seem rushed, have action scenes that don't make sense, and reading his previous issues makes me more confused as opposed to feeling rewarded.
This issue shows Emma stopping some mutants from being detained by two Orchis troopers. Of course these Orchis troopers of psi-blockers, but she canonically has Tony's repulsor rings to destroy them. A little blood thirsty, but okay, the two Orchis troopers are dead and on the ground. But then the very next panel, as Emma is leaving in her car, those three former mutant victims are attacking an Orchis trooper detaining another mutant victim. The spacing makes no sense - everything is happening within earshot of each other (as evidenced by Emma' 'fabulous' quote being heard by the three mutants), so that meant that the third Orchis trooper totally ignored the other Orchis troopers getting killed by Emma, and that Emma was unconcerned with freeing that one mutant victim.
I also have a big problem with the Stark Sentinels. Supposedly they are a huge threat that the mutants can't quite face, but yet how they are handled is all over the place.
One can be easily taken out by three X-men here (despite having Magnetic countermeasures), yet the entire X-men team in issue #23 fared poorly against a Sentinel until Magik decided to do her teleportation thing to dismantle it. In the Fall of House of X, the X-men and Avengers don't fare well against Stark Sentinel until Synch shows up with Iceman's powers.
Clearly, Duggan is 'paying off' Magik getting poisoned in #23 in issue #32, but he seems to forget how powerful Stark Sentinels are supposed to be.
Magik is attacking a base, and of course Kitty happens to be attacking the base around the same time. Everyone is in telepathic communication, and yet Emma only tells Magik to wait for backup (Lorna), not that Kitty is already on site so she doesn't have to wait.
