Mythic-tier Armor

It was the corruption, a smudge on an exposed part of Luke's skin, sizzling him like barbecue.

Corruption was a dangerous form of Aeon contamination that damaged living tissue through contact, causing pain, weakness, and eventually disrupting the body's natural functions if enough of it entered the body. It didn't mutate people, but prolonged exposure could leave them seriously injured both physically and mentally.

To battle this, Luke summoned the Olympian Serpent Bodyplate to fight with for the first time.

As previously revealed, the Olympian Serpent Bodyplate was an armor, as big as a cloak and as flexible as rubber, belonging to a Mythic beast, the Olympian Serpent.

And if there is one thing without question is that Luke's armors are like a conduit of the powers of the very beasts that once wore them. Once he wears them himself, he gains those powers as if the beast in question channels its soul through him.
