This quest requires you to deal damage to opponents while you are above them.

You can leverage the environment to get above opponents but it is far easier to build a fort to get some height on the other players. You can also get an advantage if you are higher than your opponent because you have a better vantage point and have better observability of the surroundings.

Team rumble is a good game mode for this. The later stages of the game put all players in a smaller storm circle so it's possible to build up a fort to get some height on the other team. You also respawn if you are killed so you can land back on top of your fort.
