Just a thought that came to mind

Ten numb shoots omega leader with a mangler

Rolls 3 hits

Omega leader has ten target locked

Can ten change the hit to crit?

I'm thinking he can't

You are correct. Changing a hit to a crit is a kind of dice modification, which is not permitted in this situation.

Cool

Just something to keep in mind

Same theory applies to shooting HLC at Omega Leader. If you roll any crit results, they don't get changed back to hit results.

Omega Leader just says "Go on, take you best shot!" - and then looks a bit more concerned.
