Shroomite armor

In order to get this armor, you must get an NPC called Truffle. He will sell the Autohammer, which is used to convert Chlorophyte Bars into Shroomite Bars. You will need 54 Shroomite bars to craft a full set. This amounts to 810 Glowing Mushrooms, which could take a long time to acquire without a glowing mushroom farm.

When not moving, you will immediately start entering stealth. Over the course of 1.5 to 2 seconds, you will go through rapid stages of stealth that can be seen visually as partial, to full invisibility. During this time, weapon damage and knockback will be adjusted, and will rapidly climb while stealthing, up to a 45% damage increase at full stealth. This increase affects both weapon and ammo damage.

Unlike most other Hardmode armors, this armor has three different helmets that all specialize in ranged ability, the difference is only what weapon type is boosted, arrows, bullets, or rockets.

The two ingredients, Chlorophyte Ore and Glowing Mushroom, can both be farmed with little effort, making the set easily obtained over time.

Set
Set Bonus: Not moving puts you in stealth, increasing ranged ability and reducing chance for enemies to target you.

Tips

 * Considering the Shroomite Armor only gives bonuses to ranged items, it is advised you should use ranged weapons with this.
 * For the purpose of the helmet slot, the Stynger counts as a rocket weapon.
 * Some ranged weapons, such as the Piranha Gun, do not fit into any of the three ammo categories.
 * The set alone does not truly make you invisible, as the armor glows a deep blue. For PVP purposes, consider using vanity items (like the Familiar Clothes) to ensure you are completely invisible.
 * It takes a total of 54 Chlorophyte bars and 810 Glowing mushrooms to craft enough Shroomite bars to make leggings, a chest plate and ONE helmet.
