How do I deal damage with Heat Vision enabled?
This challenge is quite complicated in itself since you will have to rely on luck. The best way to validate it is to equip yourself with a fishing rod and catch a thermal fish, which will give you this famous thermal vision for a few seconds. However, in order not to limit your chances, we advise you, once you have recovered it in your inventory, to get close to an enemy and only eat it.Then inflict 100 points of damage for the challenge to be validated. We advise you to go to Team Rumble to save time. A game should be more than enough to recover this fish and inflict 100 points of damage. Another very important point, it is imperative to be equipped with the Predator outfit.

Note that this fish can be caught in any water current on the island of Fortnite. But patience will be required, since it is not one of the most common. We recommend quieter places to avoid getting killed while trying to recover it.
