A couple of questions about missing?

So yeah, I kinda just came back to maple and I've observed something really interesting (well in my opinion it was interesting). Anyways, so I've been killing a couple of Headless Horseman on my I/L Mage and I've noticed whenever I miss on a couple of my hits with thunder spear, the hits that don't miss inflict the same damage. Is this suppose to happen? Or is it a glitch? It's not really important, but I saw it to be a little peculiar.

Here's some examples:

Oh and one more question. How come when I kill Headless Horseman, I don't gain any "Ambition EXP"?
According to the description of the Trait, it says: "Your search for strength draws followers to you. [b]Increase this trait by hunting boss monsters.[/b]

Here's an example of what I mean:

As you can see, I clearly did not gain any "Ambition EXP". So I'm wondering.. is this a glitch as well, because I'm almost sure Headless Horseman is a boss-monster.

Thanks!
