Mantis Blades are one of the deadliest Cyberware weapons to encounter in Cyberpunk 2077. However, with the right perks and Attributes, the player can turn V into a supernatural cyber-enhanced killing machine. As a rule, you'll want to invest Attribute points into the Reflex Attribute as this contains the Blades skill tree, where you'll be able to unlock perks like "Sting Like a Bee" to increase your attack speed with blade melee weapons and "Deathbolt" a powerful perk that restores health and increases speed for every kill with a blade.
