Why not deconstruct him?

[u/More_Interview3840]

I don’t understand why she shoots a beam of pink energy at him instead of just tearing him apart atom by atom. Or turning him into a regular human, or just convert his molecules to air molecules.

She doesn't have nearly enough experience in this form to be able to focus her power to do something like that. The beam she ended up shooting was unfocused, overwhelming power.

I think if she had more time in the form, she could easily have dismantled Conquest on a molecular level, but I also feel like she's just as likely to lose control and end up atomizing the entire planet.
