From Terraria Wiki. Armor is a set of equipable defense items that reduce damage taken from enemies and most other damage sources. Armor pieces are equipped by placing them in the Armor slots of the player's inventory. Placing armor in the vanity slots won't give any defense. There are 34 pre-hardmode armor sets, 24 post-hardmode armor sets, 7 robes, 2 hats, and 7 miscellaneous armor pieces.
