Blades are a species in Xenoblade Chronicles 2. They are lifeforms that are linked to a Driver who creates and summons them by touching a Core Crystal. Blades give powers and a weapon to their Driver. Each Blade plays a different role, different stats and an elemental type. They provide a distinct set of 4 Arts. Each driver can have 3 Blades equiped at the same time and can switch between them during battle. Artificial Blades can be created, those Blades will have the same capacities as regular Blades.
The attackers are focused on dealing huge damage on the enemy by unleashing their powerful arts.
The Tanks are focused on getting the aggro to protect their allies, their arts are generally arts that have huge amount of aggro or that prioritize the defense of their Driver.
The Healers are focused on making the enemy drop more HP Potions which are used to heal the party.
Blade Specials are devastating moves used by Blades in battle, the attack can go up to 4 levels of intensity if used well.

The Common Blades are created from Common Core Crystals, their name, weapon, element and stats are obtained randomly. They all have a similar global appearance and a crystal on their chest with the coloration of their elements.
Hybrids are the result of a fusion between a Human and a Blade, if the Hybrid is a Blade fused with Human cells, he is called a "Flesh Eater" but if the Hybrid is a Human who fused with a Core Crystal, he is called a Blade Eater. Both types of Hybrids can gain in power through the fusion but most Flesh Eater just loose their immortality in the process.
Aegises are a special kind of Blades that were created by The Architect to "manage" other Blades in that they hold all the information other Blades possess and update with every new bit of information the other Blades obtain. They were a measure created in order to prevent the apparition of someone like The Architect in Alrest. There are three known Aegises: Logos, Ontos and Pneuma.
