Shroomite armor

Shroomite Armor is a Hardmode, post-Plantera armor set that boosts the effectiveness of ranged weapons. It is available after defeating Plantera and is the second-strongest ranger armor available, only beaten by Vortex armor or Titan armor.

With a full set equipped, standing still causes a player to enter "stealth mode": Over the course of roughly 1.5 seconds, the player will gradually turn almost fully transparent, which also diminishes the chance that enemies will target the player. Additionally, during this time, weapon damage, critical strike chance, and knockback will each be boosted gradually up to a maximum of +60% damage, +10% critical chance, and +50% knockback at full stealth. These boosts increase both weapon and ammo damage. The buff begins fading quickly if the wearer starts moving.

Shroomite armor has three headpiece options, each providing an extra +15% damage boost that affects a different ranged weapon type:
 * Shroomite Headgear for arrows
 * Shroomite Mask for bullets
 * Shroomite Helmet for rockets

Note that this increase is applied after applying damage increases from the rest of the armor set, accessories and buffs. As a result, Shroomite headpieces provide a larger damage bonus than their tooltip would suggest.

Some ranged weapons do not receive the specialized boost from any of the three options (e.g. Star Cannon, Piranha Gun and Flamethrower), though they still receive the set stealth boost.

A full set of Shroomite armor will provide the following stats:
 * +51 defense.
 * ×115% damage of Arrows, Bullets, or Rockets, depending on which headpiece is worn.
 * +13% ranged damage for all ranged weapons, including those not covered by the headpiece of choice.
 * +25% ranged critical strike chance.
 * +20% chance not to consume ammo.
 * +12% movement speed.
 * Ability to enter stealth mode.

Crafting Shroomite Armor requires Shroomite Bars (crafted from Chlorophyte Bars via the Autohammer, which is in turn purchased from the Truffle NPC). Crafting a full set with a single headpiece requires 54 Shroomite Bars (or 810 Glowing Mushrooms and 324 Chlorophyte Ore). A full set with all three headpieces requires 78 Shroomite Bars (1170 Glowing Mushrooms and 468 Chlorophyte Ore).

Tips

 * This armor set has good synergy with the Shiny Stone, as both require the player to stand still and not get attacked to maximize their effectiveness.
 * This armor set also has good synergy with the Sniper Rifle, as stealth massively boosts the Sniper Rifle's main strengths – damage and critical strike chance – even further. With the right loadout, each rifle shot can deal over 1000 damage, killing most non-boss enemies in one hit.
 * The set does not truly make the player invisible, as the armor glows a deep blue. For PvP purposes, consider using Familiar clothes in conjunction with Shroomite armor, and with no visible accessories. With stealth active, this can render the character completely invisible to other players. Also see Invisibility Potion.
 * Wearing a Shroomite Mask with Silver Dye can make the player's head resemble a cracked skull.
 * Some Dye combinations make the character sprite appear very near invisible at night. Provided below are several links to screenshots from testing.

Trivia

 * Shroomite Armor is the only armor that has different headpieces with the same amount of defense.
 * The Shroomite Mask resembles the Sonar Goggles from the Tom Clancy's Splinter Cell series.
