Flare

The Flare is an item, used as ammo for the Flare Gun. It emits a low-level red-tinted light that will stick to surfaces it comes into contact with and will continue to function underwater. It can be found in chests or be purchased from a merchant once the Flare Gun has been obtained. The Flare is almost identical to the Sticky Glowstick in function, and will stick to blocks and fall from broken blocks in the same manner. The only key difference is that Flares, both red and blue, will burn for 10 minutes, twice the amount of time a Glowstick will last. Flares cannot be recovered once they have burned out.
