Few things shine as bright as the jewels of Hell
A rare and diseased jewel, a canker fallen from the heavens
“Gold. GOLD. GOLD! Beautiful, wonderous, Gold! I am Rich I tell you. I am the luckiest man alive!”
“Ever in my hand, lies the Blade of the Mad. It’s straight, simple craft is so alluring to me… It drives me to evil, but I love what it does. For the first blood the blade tasted was that of a human.”
A certain type of demon cannot not be hit by ranged weapons or attacks. Attacks have to be made up close and personal for the damage to mean something. Ranged attacks are to impersonal.
Possibally a way to make the ranged attacks more meaningful would be to coat the arrow head or what not with the shooters blood. Of course, they'd better be a good shot, otherwise they're wasting arrows and already bleeding to boot.
Spells: wizards might have half or no effect, preist might work due to divine intention.
