Armor

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. Armor can also be placed in vanity slots to change the player's appearance without affecting stats. Armor pieces are either crafted, purchased from NPCs, or dropped from enemies.

Each piece of armor has a defense statistic that reduces inflicted damage by half / its value, rounded up. For example, Wormwood armor grants a total of 6 defense, reducing damage by 3/, after having been rounded up. An attack cannot be reduced to zero; all attacks will always deal at least 1 damage (or 2 damage for a critical hit), regardless of the quality of a player's armor.

In addition to the defense provided by individual armor pieces, most armor types provide a Set Bonus when all three pieces of the same armor type are worn simultaneously. For example Patch Leather armor will summon 3 Snakey Bois to fight for the player.

Secrets of the Shadows adds 16 new armor sets. 6 sets can be obtained Pre-Hardmode and 1 sets in Hardmode, with most armor sets being class-specific.
