Guardian Armor

Guardian Armor is one of the five treasures of the Re-Estize Kingdom.

Description
Due to it being composed entirely of adamantite, the armor is said to prevent any instant killing attack.

Appearance
Guardian Armor is a full-plated metal set tinged with a color of reddish gold.

Abilities
Guardian Armor is crafted out of adamantite, the hardest metal known to man, and enchanted with magic that would deflect lethal effects beyond the physical. This means that the armor makes the user resistant to death magic but only up to a certain level. High level death magic like True Death or Grasp Heart would be able to kill the wearer.

Trivia

 * Adamantite so far in the anime has been portrayed as a dark metal.
