We have to destroy one first to know if it'll help, and that's going to take a while. [Maria gestures to the ground, indicating how large and deeply etched the sigils are.] And I really don't think amplifying magic is going to do anything but exhaust both of us quickly. It feels like we're leaping for what should be our last chance option - or at least a later one - first here.

[It's not a bad idea, but it's also one Maria is reluctant to jump for immediately, just in case it turns out that blasting out a sigil doesn't help, or it takes longer than they expect it to. There's too much that can go wrong.]
