Deathstorm is made up of pure thermodynamic energy, so Team Flash use the Mental Augmentation Chamber to harness particles from its home dimension and then beam them into Frost's consciousness.

Deathstorm: I was born a long time ago-- before Maltus, before the stars, during that lonely, blackest of nights. I was there when the first gas cloud sank and collapsed. I was there when the first beings drew their final, hissing breaths. I am decline. I am entropy. I am the master of death and all of its inhabitants.
Eddie: I thought my sacrifice would mean something. That I could erase the Reverse Flash from existence. That, finally, I could be a hero. But then Eobard Thawne came back, again, and again, and again, and again. What I did didn't matter at all. I died for nothing, and now you've made the same mistake. You sacrificed yourself for nothing.
Iris: I saved Barry, and I helped stop Armageddon.
Eddie: And then, what happened? The timeline got reset, but you're still suffering the consequences. Can't you see? Your death is gonna be just as pointless as mine.
Frost: Boy, was I stupid for ever thinking that was possible, because it doesn't matter. Doesn't matter how many life coaches I get, or if I get my own body, or do a bunch of art, or get my own boyfriend, because I'll always just be a copy of the original. An echo. 'Cause I've never been really alive. And now, that's gonna get Caity killed.
Chillblaine: Frost... If you are not really alive, where does that leave me? You're the only person I've ever cared about more than myself, or at least equal to myself.
Frost: I guess we're both screwed up then.
Chillblaine: Yeah, that's definitely true. Look, the way I see it, you and I have been through a lot, right? And through all of those ups and downs, I, for one, have seen you have loads of emotions-- all kinds-- especially when it comes to Caitlin. You love your sister like crazy. And wherever that love came from-- you know, whether you were born with it, or your dad gave it to you, or you put it together yourself over time, built it with pain and heartache-- that love is as real as it gets. Believe me.

The Bottom Line
Some of the best moments of The Flash Season 8 have centered around Frost and her development, so naturally the showrunners have to put a stop that by killing her off, in an episode that seems to be both full of padding and yet underdeveloped in equal measure.
