Hallowed armor

Hallowed armor is a hardmode armor. Historically, it used to be the highest tiered armor from its introduction. It also used to be crafted from all the lower-down hardmode armors (Cobalt, Mythril and Adamantite, respectively), as well as 20 of each of the boss souls from the hardmode bosses of the time, one for each different piece. In the console version, the hallowed armor is one tier below, and an ingredient to craft, the Console exclusive armors.

With the 1.2 update, its crafting recipe has been simplified (now only requiring 54 Hallowed bars for a full set). Also, it has been superseded by a few new additional armor sets; the most comparable of which would be the Chlorophyte armor, which, like the Hallowed Armor and many other hardmode armors, also has a ranged, melee and magic set.

This armor has both an after-image and pulsing aura visual effect, which are also visual effects for the Cobalt and Adamantite armors, respectively.

As for the 1.2 update, the hallowed armor is not crafted with hallowed bars. And is no longer the strongest armor on the game.
