The stakes don't need to be upped anyways, the WoL is not a god of destruction, every big feat we achive is through the help of many people or with borrowed power. And even without that just because we beat something powerful doesn't mean we have just as much destructive power as whatever we kill. Someone at the level of Gaius would still be a great threat to us, the WoL is still human. (1/14th denser than most thanks to Ardbert, but stil...)
