Spectre armor

Spectre Armor is a Hardmode, post-Plantera armor set that offers magic weapon boosts. The set consists of the Spectre Robe and Spectre Pants, with either the Spectre Hood or Spectre Mask  headpiece. 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.

Crafting a full set with one headpiece requires 54 Spectre Bars (27 Ectoplasm and 54 Chlorophyte Bars (324 Chlorophyte Ore)). The full set with both headpieces requires 66 Spectre Bars (33 Ectoplasm and 66 Chlorophyte Bars (396 Chlorophyte Ore)).

Crafting a full set with one headpiece requires 54 Chlorophyte Bars (324 Chlorophyte Ore) and 54 Ectoplasm. The full set with both headpieces requires 66 Chlorophyte Bars (396 Chlorophyte Ore) and 66 Ectoplasm.

Spectre Mask set bonus: Homing orb projectiles spawn when dealing magic damage to an enemy, which attack nearby enemies, or the same enemy. Orb damage is 50% / 100%  of the damage dealt by the magic weapon fired, before it is doubled by a critical hit (if a critical hit deals 200 damage, the orb will have  50 / 100  base damage).

Spectre Hood set bonus: Life steal orbs spawn when dealing magic damage to an enemy, which fly to the player and restore health by 20% of damage done (eg. dealing 50 magic damage heals 10 health). In team multiplayer, the player with the lowest health is healed instead. Note that equipping the Spectre Hood incurs a -40% magic damage handicap.

Tips

 * One of the most efficient ways to play with this armor is by owning both Hood and Mask and switching between them, depending on the situation. This way the player will be able to both keep themselves alive and deal continuous high damage.
 * 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.
 * Magic Cuffs or Celestial Cuffs synergize well with the Spectre Hood as they capitalize on any damage taken; with a highly-damaging weapon like the Razorpine, it is possible to maintain both health and mana at comfortable levels.
 * A good idea for boss fights/events is to make a "healing station" via the set bonus from the Spectre Hood. To create one, place a few statues in a pool of lava. Wire a 1 second timer to the statues and put two Nimbus Clouds above the spawned enemies, dealing damage and generating healing orbs. The lava will destroy any drops to clear out the item drop limit, and the healing will compensate for the 30 defense.
 * By equipping enough accessories that boost magic damage (such as a Sorcerer Emblem, Celestial Emblem, and Celestial Stone) it is possible to stack up enough damage increases to completely negate the Spectre Hood's 40% reduction in magic damage.
 * A Magic Power Potion alone will negate all but 5% of the reduction to magic damage when using a full set with the Hood, causing greater damage and thus greater healing.

Trivia

 * Spectre Hood is the only armor that decrease player's stats.
 * " Spectre " is another word for "ghost" or "spirit", alluding to the fact that the Ectoplasm, required to make them (or spectre bars), is dropped by Dungeon Spirits.
 * Although Re-Logic is based in the United States, "spectre" is the British spelling of the word, with the American spelling being "specter".
