I really can't imagine the Doomed Bastards taking the relatively safe and certain route. In anything. Ever.
I mean, they took out a demon lord in his throne room. That couldn't have been absolutely necessary. Sure, they couldn't have just left him there, but at some point between "There's cultists down there" and "The Lord of Undeath will feast on our souls", there must have been a few instances where they could have just walled something off or thrown a
consecrate on it and achieved basically the same effect, at least for the moment, that they got from leaping into a high priest's sacrificial chamber and going toe-to-toe with something nine feet tall.
But pretty much every time the Doomed Bastards have ever encountered a situation, they've gone for the thorough, unlikely-to-succeed route that got the job done right (and/or killed them in the process). When Tiros found out what the Duke was like, he could have opposed him politically, hampering the damage he could do. Instead, he staged a coup to remove him once and for all. When his accomplices found out about his capture, they could have found a new leader and invoked their martyred one's name. Instead, they went in through the nastier entrance of the world's most elaborate execution device to rescue their leader and pick up where they left off. When Talen was turned into a vampire, they could have just destroyed him and mourned his loss. Instead, they dragged one of the most powerful undead creatures they knew of to the heart of their city and tried everything they could to cure him. The dragon, the ravager spawn, the ghoul army, the corpse collector, the list goes on of situations when rational compromises just weren't their thing.
Besides, so what if the Ravager's creators couldn't kill it? They're the ones who thought it'd be a good idea to make it in the first place, how clever could they have been?
