The Lightwardens of Final Fantasy 14: Shadowbringers make up some of the MMO's most memorable bosses. They are horrifying and have similar death rules to Archdemons from Dragon Age. That being, if they are killed, their being possesses and takes over whoever kills it and turns them into a new Lightwarden. Due to this, the only person that can kill these Lightwardens is the Warrior of Light (or a Minfilia), as their body can handle way more aether than the average individual.
