Ignite sructures is a challenge that's regularly featured in Fortnite, tasking players with setting fire to buildings.

While fire is pretty easy to come by in Fortnite, there are ways to speed up the process of completing this challenge.

Here's how to ignite structures in Fortnite, and what you'll earn for doing so.

How to ignite structures in Fortnite

To ignite structures in Fortnite easily, pick up Fireflies and toss them at buildings.

As the fire spreads, you'll destroy walls and 'structures'. Because of how fire destruction works in Fortnite, there are some buildings that are better for this challenge. Namely ones made of wood.

In Chapter 3 Season 4, the house at Grim Gables is a great place to complete this challenge, given that it's mostly made of wood.

Head to the location shown on the map embedded above, and look around for Fireflies. These are usually found as ground loot.

Once you have Fireflies, just throw them at the house. Try not to throw multiple jars at the same spot. Instead, circle around the building and hit different locations. As the fire spreads, more and more structures will be destroyed.

Note that while Fireflies are the most common fire-based item in Fortnite at the moment, other weapons and items can be used to start fires. For one, gas canisters can be thrown and detonated to start fires. There are certain fire bows, and even flamethrowers that are sometimes added in too. This all depends on the ground loot. For now, go for Fireflies.
