What materials are required to craft the Hallowed Armor in Terraria?

To craft the Hallowed Armor in Terraria, you need to gather specific materials and follow a series of steps. Hallowed Armor is a powerful set of armor that becomes available after defeating the mechanical bosses in Hardmode. It is one of the best armor sets in the game at this stage and provides significant bonuses depending on the class you are playing. Here is a detailed guide on how to craft it.

First, you need to defeat the three mechanical bosses: The Destroyer, Skeletron Prime, and The Twins. Each of these bosses drops Hallowed Bars, which are the primary material required to craft the Hallowed Armor. You will need a total of 54 Hallowed Bars to craft the full set, which includes the helmet, chestplate, and leggings. Each piece of the armor requires 18 Hallowed Bars, so you will need to defeat the mechanical bosses multiple times to gather enough bars.

Once you have the Hallowed Bars, you need to craft the armor at a Mythril or Orichalcum Anvil. These anvils are crafted using Mythril or Orichalcum Bars, which are obtained by smelting Mythril or Orichalcum Ore. You can find these ores in the Underground or Cavern layers of your world after breaking Demon or Crimson Altars with a Pwnhammer, which is dropped by the Wall of Flesh. To craft the Mythril or Orichalcum Anvil, you need 10 Mythril or Orichalcum Bars.

The Hallowed Armor set provides different bonuses depending on the helmet you choose. There are three types of helmets: the Hallowed Mask for melee, the Hallowed Helmet for ranged, and the Hallowed Headgear for magic. Each helmet provides class-specific bonuses, so choose the one that matches your playstyle. The chestplate and leggings are the same for all three sets and provide general defense and movement speed bonuses.

Here are the specific recipes for each piece of the Hallowed Armor:
- Hallowed Mask: 18 Hallowed Bars at a Mythril or Orichalcum Anvil.
- Hallowed Helmet: 18 Hallowed Bars at a Mythril or Orichalcum Anvil.
- Hallowed Headgear: 18 Hallowed Bars at a Mythril or Orichalcum Anvil.
- Hallowed Plate Mail: 18 Hallowed Bars at a Mythril or Orichalcum Anvil.
- Hallowed Greaves: 18 Hallowed Bars at a Mythril or Orichalcum Anvil.

To optimize your resource gathering, you should prepare for the mechanical boss fights by setting up arenas and gathering potions and buffs. Create a large, flat area with platforms for mobility, and place campfires and heart lanterns for health regeneration. Use potions like Ironskin, Regeneration, and Swiftness to increase your survivability and damage output. Additionally, make sure you have a good weapon and armor set before attempting these bosses. Titanium or Adamantite Armor is recommended, as they provide strong defense and set bonuses.

A common mistake is underestimating the difficulty of the mechanical bosses. These bosses are significantly stronger than their pre-Hardmode counterparts, so make sure you are well-prepared before engaging them. Another mistake is not farming enough Hallowed Bars. Since you need 54 bars for the full set, you may need to defeat the bosses multiple times. To save time, focus on defeating The Destroyer first, as it drops more Hallowed Bars compared to the other bosses.

Advanced techniques include using specific weapons and accessories to maximize your damage output. For example, melee players can use the Shadowflame Knife or the Amarok, while ranged players can use the Daedalus Stormbow with Holy Arrows. Magic users can benefit from the Crystal Serpent or the Sky Fracture. Additionally, using accessories like the Warrior Emblem, Ranger Emblem, or Sorcerer Emblem can further enhance your damage.

In summary, crafting the Hallowed Armor requires defeating the mechanical bosses to obtain Hallowed Bars and using a Mythril or Orichalcum Anvil to craft the armor pieces. Prepare thoroughly for the boss fights, choose the appropriate helmet for your class, and optimize your gear and accessories to maximize your effectiveness. With the Hallowed Armor, you will be well-equipped to tackle the challenges of Hardmode and progress further in the game.
