Crafted Augments
Twelve augment parts are made at the crafting table instead of dropped by mobs.
Install each one at the Augmentation Station like any other part.
Legs
Four parts compete for the Left Leg and Right Leg slots.
Hydraulic Leg
Augment: Leap. Press Left Alt while standing on the ground to launch yourself in the direction you are looking. Look straight up for a vertical jump. It has a cooldown of just over a second.
Servo Knee
Augment: Step Up. You walk up full blocks without jumping.
Shock Absorber
Augment: Prevent Fall Damage. You take no fall damage from any height. It pairs well with the Hydraulic Leg.
Tendon Weave
Augment: Walking Speed. Raises your base walking speed to two and a half times normal.
Utility Arms
Six parts compete for the Left Arm and Right Arm slots. These three work on their own.
Magnetic Coil Arm
Augment: Magnet. Pulls dropped items within 5 blocks toward you. Crouch to switch it off, for example when you want to throw something away.
Ender Coil Arm
Augment: Ender Magnet. Teleports dropped items within 5 blocks straight into your inventory. Items that do not fit stay where they are. Crouch to switch it off.
Hydro Drill Arm
Augment: Underwater Mining Speed. Removes the mining slowdown for having your head under water, the same as Aqua Affinity without the helmet. Mining while floating is still slow, so stand on the bottom.
Throwing Arms
These three fire on a key press, each with a one second cooldown. They use no ammunition, and what they throw cannot be picked up.
Trident Launcher Arm
Augment: Bouncing Trident, on Y. Throws a trident that ricochets once off the first block it hits and carries on. Hitting a mob ends the bounce.
Volley Trident Arm
Augment: Spreading Trident, on U. Throws a trident that splits into three when it hits a block, fanning out from the point of impact. Aim at the floor or a wall near a group of mobs.
Syringe Robot Arm
Augment: Random Potion Throwing, on G. Throws a splash potion chosen at random from Healing, Harming, Regeneration, Swiftness and Slowness. Two of the five hurt or slow whatever they hit, so do not throw it at your feet.
Body and Heart
Buoyancy Tank
Augment: Creative Flight, in the Body slot. You can fly the way you do in creative mode: double-tap jump to take off, in water or out of it. It takes the Body slot, so it replaces a Dolphin Fin or Photophore Skin.
Auxiliary Ventricle
Augment: Bonus Hearts, in the Heart slot. Doubles your maximum health, from 10 hearts to 20. It shares the Heart slot with the 
Eldritch Heart augment, so you choose between more health and healing in water.
