Entity Death

Entity Death is an extremely rare enemy that has no spawn conditions. It can spawn anywhere and anytime. It also has little to zero drops, and can be considered an OP enemy like the Dungeon Guardian. When spawned, it also says a message in red in chat "Fate draws near." If the player dies, Entity Death will despawn. Entity Death also spawn in a random location around the world and will gradually make it's way to the player.

Behavior
Entity Death has a similar behavior to Wraiths or Reapers, but movement does not go smoothly and can be descriped as glitchy. It phases around and can phase through walls, and can phase through basically anything. Entity Death can one shot the player most of the time when it spawns, and gives the player all kinds of debuffs before dying. It is almost invincible and undefeatable, due to it's 99 damage reduction, 100 armor penetration, remarkable attack damage and health. It cannot be butchered by any mod as well, and can dodge an attack 50% of the time. Killing it however is very rewarding. One of the following items except for coins are guaranteed to drop.

Drops

 * Void Robe - 33%
 * Deathorn - 33%
 * Screenphaser - 33%
 * 80 - 100%

Trivia

 * A flow of mystery and instant death passed my mind, and because a story is usually an expression of emotion by the author, Entity Death is the incarnation of the emotion of fear and loneliness. Of course that's not what I'm feeling.
