[at first it seemed like it might not work again, as the monster growled and glared at Thash but didn't attack. When he started yelling at it and threw a small crate at it though, it got pissed off and tried to bite him.]

[when Dave attacked the monster's neck, it was wide open...however, it's body was covered in thick armor like scales. If Dave had some kind of supernatural strength or piercing ability he might be able to do serious damage, but if all he was working with was human strength behind a normal but sharp katana, the damage would be less severe and only cut into the scales to make it bleed a little]
