“ The ancient Empire of the Golden Crystal fell so long ago that little is known of them besides their legendary magical power. Supposedly, in the Golden Age of the Crystal Empire, cities were filled with enchantment, spells far beyong the ability of modern magi.
A tomb robber has returned to civilization with something never seen before: Ceramic vials of reddish dust that supposedly enhance a magician's power tremendously when the dust is sprinkled upon the floor of his workroom. The rogue selling the vials claims that they were recovered from a ruin of the Crystal Empire, but can he be believed?”
“ 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.”
