Completing weekly challenges or the Volcanic Assassin Pack Quests? You'll need to know how to ignite structures in Fortnite Chapter 3: Season 2.

Some Fortnite quests are easier than others, be it for XP or rewards. Some require players to deal damage with a particular weapon or visit a certain number of locations in a single match. Others are a bit more involved, like setting structures on fire.

If you're completing the Fortnite Volcanic Assassin Pack Quests, then you'll be encountering this quest. The tricky part comes with knowing what counts as a structure and how to set it aflame.

How to Ignite Structures in Fortnite Chapter 3: Season 2

The key tool you'll be using for this quest is the Firefly Jar. These throwables act as incendiary grenades, spreading fire once it explodes after being thrown. To find Firefly Jars, players can take their chances by searching chests. But, there's an easier way.

Forest-like areas or groups of trees will usually have Fireflies swarming around, identified as lightly glowing dots. Interact with the swarm of flies and you'll collect a few jars of Fireflies. Players can stack up to six.

Once you've collected your Fireflies, simply throw them at any structures. The easiest to burn down are wooden structures, such as those built by other players.

This quest shouldn't take too long to complete, earning players a notch on the Volcanic Assassin Pack Quest.
