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. The effect of these orbs 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 270 /  324 Chlorophyte Ore). The full set with both headpieces requires 66 Spectre Bars (33 Ectoplasm and 330 /  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. The orbs deal 100% /  50% 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  100 /  50 base damage).

Spectre Hood set bonus: Life-stealing orbs spawn when dealing magic damage to an enemy, which fly to the player and restore health by 20% /  8% of damage done (e.g. dealing 50 magic damage heals  10 /  4 health). In multiplayer, the player with the lowest health on the team is healed instead. Equipping full set with the Spectre Hood / the Spectre Hood incurs a 40% magic damage decrease.

Tips

 * If the player changes their mind, the helmet piece can be shimmered and crafted into the alternative.
 * One of the most efficient ways to play with this armor is by owning both the Spectre Hood and the Spectre 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.
 * 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.
 * Spectre armor with the Spectre Hood is widely considered useless against the, whose Moon bite debuff disables lifesteal effects, unless one moves far enough to avoid his tongue to latch on. However, such strategy is usually ineffective since Moon Lord can teleport to the player if they move too far from him. Despite this, the buff may still be very useful, as in classic worlds there is often a time frame while the core is not exposed in which the moon bite debuff is not applied, usually after the Phantasmal Deathray has been used. Homing weapons with fast projectiles, especially the Nightglow, are useful for healing during this brief period, as the projectiles can build up, and heal you the second Moon Bite wears off.

Trivia

 * The Spectre Hood is the only piece of armor that decreases the player's stats. On the, the decrease is only caused indirectly, via the set bonus.
 *  is another word for ghost or spirit, alluding to the fact that the Ectoplasm, required for crafting the armor set, is dropped by Dungeon Spirits.
