So, we all know that our lovely Clan Centurio has us running 'round Ivalice, slaying all the baddies, but after completing the Atomos hunt, I stopped to wonder.

"This creature is so kewl,and has beautiful crystals on it's back, maybe I shouldn't kill it..."

I then mercilessly slayed the beast and returned to Nalbina to reap my goodies.

The moral of the story is:

What is the mark so cool/beautiful/interesting, you felt it a shame to kill it?

P.S. If this topic has been done, one of you lovely mods can just close it.
