Spider Armor SetBee Armor SetNOTES1. You must have all armor in your inventory at some point to get the achievement
2. It is not necessary to equip each piece on your character
BASIC STUFFAll armor (that are not found) are crafted at a workbench or anvil
You also need a furnace to smelt metal bars from ore to make the metal armors.
A regular furnace is made from 20 stone blocks, 4 wood, and 3 torches.
A Hellforge can be found in the Underworld
A Hellforge plus 30 adamantite or titanium will yield an Adamantite/Titanium Forge which can be used to smelt ANY bar from ore
Hallowed Bars are found from slaying Normal Mode bosses
You must break Demon/Crimson altars to make Orichalum, Cobalt, Palladium, Mythril, Adamantite, or Titanium to spawn in your world. The more altars you destroy, the more ore is created.
Souls are obtained from creatures in their respective biomes, or from farming bosses
Shroomite bars are made at an Auto-Hammer crafting station, which is sold by the Truffle, using Chlorophyte Bars and Glowing mushrooms
