Frost armor

The Frost Armor is an armor set that grants the ability to inflict Frostburn on enemies with melee or ranged attacks when the whole set is worn, as well as causing all ranged and melee attacks to give off light - This makes it very useful for exploring caves.

Ice Golems will drop the Frost Core required to craft one piece of this armor every time they are killed ( in PC), but on console they just give the armor; therefore, it takes three Ice Golem kills to get the full suit in PC. Ice Golems spawn in the Snow biome during a Blizzard in Hardmode.

The Frostburn debuff is particularly devastating when used against worm enemies because it affects each segment, thereby multiplying the damage dealt by the number of segments.

Visually, wearing the set causes a "snow trail" to be left behind the player as they walk, similar to running with Hermes Boots. Also, taking damage causes the shattering sound heard when breaking through ice.

Trivia

 * If the Breastplate and Leggings are paired with a gold helmet, and you dye all pieces with Blue Flame and Black dye, you will get an afterimage and pulsing aura, akin to Hallowed armor. This was the armor Red used to wear, before his specific set was added.
 * The Frost Armor may be easier to obtain on the console version as Ice Golems still drop the armor pieces as of 1.2.(Might be the same difficulty because the ice golem drops a random part, so you can get 3 helmets, where you would get 3 ice cores(which can be used to craft any part) on the pc version, yet need Hallowed Bars especially when you started Hardmode
