In game - yes because there is no quest for some reason in act 3
Lorewise - bro you ever played this game.
Those are the options that make perfect sense lorewise:
Ask Dammon for help, as he promised
Steal tech from Steel Watchers
Ask Gondians for help
Make a pact with Mizora
Make a pact with Raphael
Ask Gale or any sorcerer to conjure some spell
Buy her out from Zariel with soul coins

Here, please explain why any of those options shouldn't work and if your answer is going to be "because this isn't in game" just go troll someone else
