Joostmod/Death Knight

Death Knights are rare, powerful hardmode enemies that spawn in the Dungeon after Plantera has been defeated. It will occasionally do a spinning jump attack where they swing their sword around them. If you are not within line of sight of the Death Knight it will emit cyan particles noting that it will jump attack when you get in sight. When below half health it will spawn 4 cursed skulls around it every 3 seconds.
