Spectre armor

Spectre Armor is a Hardmode, post-Plantera armor set that offers magic weapon boosts. It is one of the 3 endgame armors available for the PC version, the others being Beetle armor and Shroomite armor. Crafting a full set with one headpiece requires 324 Chlorophyte Ore and 54 Ectoplasm. For both headpieces, 396 Ore and 66 Ectoplasm are needed.

Wearing a full set causes small white orbs to manifest whenever the player hits an enemy with a magic weapon. What these orbs do depends on the headpiece option chosen. The Spectre Mask causes the orbs to act as homing projectiles, while the Spectre Hood causes the orbs to travel to a player, healing them.

Spectre Mask:
 * Homing orbs (set bonus): Dealing magic damage spawns orb projectiles on impact that home in on nearby enemies, or the same enemy. Orb damage is 1/3 the damage dealt by the magic weapon fired.
 * Maximum mana boosted +60
 * Mana usage reduced -13%
 * Magic damage and critical chance boosted +5%

Spectre Hood:
 * Life steal orbs (set bonus): Magic damage dealt by the player spawns healing orbs that fly to the player, restoring health by 20% of damage done (dealing 50 magic damage heals 10 health). In team multiplayer, the player with the lowest health is healed instead, rather than necessarily healing the player that caused the orbs to appear.
 * All magic damage dealt by the player is reduced by 40%.

Tips

 * Casting long-lasting, multi-hit spells, such as the Nimbus Rod, Rainbow Gun or Magnet Sphere, is a great way to make effortless use of the set bonuses.
 * The combined effects of Mana Sickness and the Spectre Hood's damage reduction will render many magic weapons too weak to be effective, so players should find an alternate means of restoring mana.

Trivia

 * "Spectre" is another word for ghost or spirit.
 * The female version of the armor, along with having different textures, is slightly more blue than the male version.
