The Mayan Armor was a set of armor created by the Maya through the use of scavenged Isu Shards of Eden. It was hidden in a vault in Tulum, which could only be opened with a number of keystones scattered across the West Indies. Their locations were typically marked with the presence of Mayan stelae nearby.
The Mayan Armor was forged by the Maya from scavenged Isu materials. It has magnetic properties, allowing it to deflect metallic projectiles. When Edward Kenway wore the armor, he was immune to damage from bullets and firearms.
