"I know they get a bad rap, but I like kobolds. They're intelligent, have a healthy fear and respect of dragons, and make a mean whiskey."
Kobold Firewater is a strong white whiskey made from corn, sugar, and yeast, mixed with a dash of alchemy. A powerful alcohol, the Constitution saving throw DC to avoid intoxication is 20. What makes kobold firewater truly unique is the reaction it has when imbibed by someone with draconic heritage*. To those individuals it acts identically to a Potion of Fire Breathing.
*What draconic heritage means is, of course, up to the DM. In my games it includes kobolds, half dragons, dragonborn, and sorcerers with the draconic bloodline.
