From Extermination 8.2 (bold mine):
“I’m telling you your chances now because you deserve to know, and we so rarely get the chance to inform those individuals brave enough to step up and fight these monsters. The primary message I want to convey, even more than briefing you on the particulars of his abilities, organizing formations and battle plans, is that I do not want you to underestimate Leviathan. I have seen too many good heroes,” he paused for a fraction of a second, “And villains, too, die because they let their guard down.”
That said, I would advise you to think of him as having many of the strengths of both siblings at once. You’ve seen the videos on television and the internet. You know what he is physically capable of. I want to be clear that despite the image he might convey, he is not stupid, and he can display a level of cunning and tactics that can and will catch you off guard.
“Our second priority is that we need to find ways to hurt him. If you cannot, if your attacks are deflected or prove otherwise useless, work to support those who can. It is vain to hope to kill him, but he can be whittled down enough that he will flee back to the ocean, and if we hurt him enough, it may delay the time before he is capable of making another attack elsewhere.”
Good job, Armsmaster, of ignoring every bit of advice Legend gave.
