Necromancer

The Necromancer is a Hardmode enemy found in the post-Plantera Dungeon. It is most common in areas backed by Brick Walls. These are identified by the related Faction Flag, the Necromantic Sign.

Necromancers attack by rapidly firing beams of purple light at the player which reflect off walls multiple times. They travel at an extremely high velocity, being fired nearly instantly, and inflict the Slow debuff. Necromancers teleport to a different location on-screen after firing six times or when being hit.

Tips

 * Weapons that stick to enemies are exceptionally useful, as they remain on the Necromancer after the teleport. The Piranha Gun,, and are viable options.
 * Weapons that deal high damage in single hits are effective against Necromancers. Weapons that fire multiple projectiles simultaneously may be able to land multiple hits before they teleport as well.
 * Weapons with homing capacities or minions can continue to track Necromancers after they teleport. The Sanguine Staff is particularly effective at this, often causing the Necromancer to rapidly teleport as it takes damage and quickly dies.

Trivia

 * Despite inflicting the Slow debuff, they do not drop Fast Clocks.
 * s are magicians that engage in communication with the dead, although in Terraria they do not have this ability.
