Ya know how, when you're taking on an NPC, you get that display showing its health and what not?
For regular targets, it's just a simple grey border, but for some, it's red, maybe with teeth. Heck, there's one guy in the Fields of the Dead that's red, has teeth, horns and an evil grill - man, I cannot beat that guy.
My question is, is there a guide to what the various graphics on these displays mean? I've come across some where I'm like twice their level, but they still eat my lunch - like in the Black Castle.
So, is there anything that describes what the different displays mean?
