Hallowed armor

Hallowed armor is an armor set from 1.1 update. The helmet of the armor set has three variations, one for each fighting class, melee, ranged, caster. Its takes the full sets of Adamantite, Cobalt and Mythril armor, 20 Souls Of Might, 20 Souls of Fright and 20 Souls of Sight to make this armor.

It gives visual effects similar to Cobalt Armor and Shadow Armor.

It's the most powerful armor in the game and the hardest armor to get, since you need to defeat each of the Hardmode bosses first plus the full Cobalt armor/Mythril armor/Adamantite armor sets in order to craft it.
