Sandkheg's Hide

 is a potent alcoholic beverage produced in the deserts of Marquet. It is made using the venomous bile or spittle of sandkhegs (a desert-based variant of ankhegs) found within the Marquesian Desert.

Uses by Vox Machina
During, Grog purchased two bottles of Sandkheg's Hide for a total of 800 gold, though each bottle's price was only 350 gold. Upon showing the liquor to the party, Percival and Keyleth promptly sampled it, becoming immediately intoxicated. When Scanlan was given some, it numbed him from the nose down, although Grog himself enjoyed it as a nightcap. Grog later shared some with Jarett Howarth, a native Marquesian, and they both strongly felt it.

Sandkheg's Hide also made a cameo appearance in the semi-canonical.

Quotations
Percy and Keyleth: (affirmative grunt) Grog: Does it taste good? Percy and Keyleth: (dissenting grunt) Vax: Do you recommend it? Percy and Keyleth: (non-committal grunt) Matt: (after Grog's 29 constitution saving throw) You drink it. You feel the sparkling numbness begin to spread across your throat. It's strange. It's weird. It's exhilarating. It triggers your adrenaline, and you almost go into a rage from the instinctual reaction of that sort of chemical release in your brain. You hold it in place, and you sit there a second and stare as it slowly goes down your system. You feel the warm, curling burn from inside your belly that fine alcohol gives you, that little shimmer of pins and needles down the back of your neck and your spine. Your vision begins to blur a little bit. It takes you a lot of alcohol to get trashed, but you're a little buzzed.
 * Treev Bonebreaker: "They hold it down and just squeeze its abdomen and the whole sandkheg spews out into this little glass barrel and then you pay for it. Top dollar."
 * Vax: (to the very intoxicated Percy and Keyleth) Can you feel this?
 * Grog: Could I take a shot of the sandkheg bottle? I would like to slowly start building up an immunity.
