The Grade of the Mech or Weapon signifies its rarity. The rarer the item, the more resources it requires for an upgrade. Also, the Rarity of a Mech or Weapon influences its Blueprints drop rate from Crates. However, rarer items need fewer Blueprints for a Level upgrade.
Please note: Grade cannot be changed.
