I know, it's a weird question, but can the Dianoga suffer more than 20 damage? It should be obvious that no, it cannot, but I can't support that in the rules.
It seems to hinge on whether or not the Dianoga is a figure, in my mind. If it is a neutral figure, it falls upon this sentence in the Rules Reference: "A figure cannot suffer <damage> in excess of its Health." But the mission card doesn't say the magic word "figure" on it. But the card does use the term "defeated", which refers only to figures in the rules reference.
However, under attacking an object: "If an object suffers <damage> equal to or greater than its Health...". This shows that objects suffer damage beyond their health total. Of course, the Dianoga's mission card doesn't say it's an object either!
This matters since, in the mission, you get damage tokens equal to the damage it suffered. You can sneak a few extra points off of the Dianoga if it is an object and not a figure.
Has this been officially ruled anywhere? I've asked my group about it, and one of them said it was ruled at Worlds as not taking more than 20 damage, and he remembers it came up at GenCon too. But I can't support it looking at the rules, and seeing on this forum people have said it's an object (how can you tell?).
This kind of stuff should be in the FAQ.
Thanks,
