goblins that bleed beer.
you may have just cured farming.
hahahaha. dwarves would then technically be vampires, requiring the body fluids of other creatures to survive. all that "is now working slowly due to lack of alcahol" would take on such a double meaning! and different creatures would have different beverages. goblins could be sewer brew and gutter cruor, elves strawberry wine and sunshine, dwarves all the dwarfy drinks like dwarven beer, rum, and ale, and humans depending on where they are from - river spirits, swamp brew, longland beer, etc. "my this human has a fine vintage, grown on the banks of the dazzling river by the jungles of creeping, if i am not mistaken."
funnily, this means elves would be a valuable commodity, you would probably want to farm them somehow like livestock, as sunshine is the most valuable alcoholic beverage present, sun berries being hard to get.
if you are like me and you wonder why the dwarves sometimes put up with the crazier dukes and tax collecters you occasionally get, then nobles would have more expensive and desirable alcoholic bloods. this would mean the rabble beneath them are eternally trying to find ways of violently removing them for feeding purposes, and that royal guard could actually have a use for once.
cue cartoons and accounts of hordes of red eyed crazed dwarves murdering every sentient creature in sight and feasting of their lovely warm intoxicating juices. i smell a modding project and some community forts/adventure challenges... perhaps adding bucherable and tamable tags to everything then adding booze as a byproduct...
aah, first globlins, now boozy vampire dwarves. what will this thread spawn next?
