Q. Some cards say they automatically kill a certain type of Monster (like the Potion of Halitosis and the Floating Nose, or the Churninator and Level 1 monsters). Can anyone interfere with this? Can anyone play a Wandering Monster?
A. You may have automatically killed the monster in question, but your fellow munchkins still have a reasonable time to respond. They probably cannot do anything to help the now-defeated monster, but they can still wander in a new one for you to fight. (But if the monster had special "bring in a friend" rules, such as Undead and Bats, you cannot use those rules, because the original monster is no longer there.) (See Important Note #4.)

You're right that it isn't 100% explicit, but the intent is that unless you can defeat all of the monsters you face, you don't get any rewards, including the level. There are a couple of special cases where that is not the case (such as when another player uses a
Transferral Potion on the second monster), but in general, you have to defeat everything you see to get the rewards.
In the far-off future where I'm given free hand to rewrite everything, I will be sure to make this very clear. Or just remove instakill effects.
