This Unreal Engine 5.3 Gameplay Ability System video is about applying a Burning Damage Effect through the Gameplay Cue system.
We start by creating the Burning Niagara System, using a nice animated fire material from the Starter Content, and then create the Burning Damage over Time Gameplay Effect with Gameplay Cue Tag, and lastly, the Gameplay Cue Notify Actor itself, which just applies the Niagara System and a workaround for a long standing bug mentioned in the forum post below, that resets the Niagara System so that it shows up when being applied again.
