— The Sniper on slaying vampires
The Garlic Flank Stake is a miscellaneous item for the Sniper. It is comprised of two bulbs of garlic that dangle from the Sniper's bullet pouch, as well as a blood-stained wooden stake fastened around his left leg by a pair of leather straps.
This item can only be worn around Halloween or during a Full Moon; at other times of the year, it does not appear in gameplay, unless the server has Halloween mode enabled. However, it can be equipped at any time and can still be viewed on the loadout screen even when it is not visible during games.

- The Garlic Flank Stake was added to the game.
- In traditional folklore, vampires are repelled by garlic and can be killed by a wooden stake driven through the heart, making the two items essential tools for vampire hunters.
- This item's name is a pun on flank steak; the garlic and stake worn by the Sniper are flanking his sides.
