Dataminers had spotted its presence for a little while in the game's code lines. It's now officially available in-game, it is the Firefly Jar. The item works like a molotov, burning everything in its path and inflicting 40 damage points. Its description is rather explicit "Burn Baby."
Warning: Firefly Jar is only be available at nightfall. To find it, you'll have to search in the bushes or tree branches.
By touching wood, the item will reduce it to ashes. This is true for trees, but — although the information remains to be confirmed — this should also be the case for wooden constructions.
This item is likely to be quite popular among players. For the moment, it isn't known whether the jar will be available in competition. In its latest press release, Epic Games explains that it will make all items available in Arena, before making updates according to the feedback.
