Strength: 3 tons to 3.4 tons
Speed: 40 mph to 46 mph (Agility increased slightly, too.)
Durability: Slightly higher durability to piercing/slashing weapons (Rather minimal, just harder to chop him in half or cut off his limbs with monomolecular weapons)
Reflexes: 0.02 to 0.018
Regeneration boosted lightly, a few seconds faster than what it would usually take to heal something.
Rinkaku: Two of his tendrils equivalent to the power an astartes can output (as they can block an attack from him.) Each tendril now having 1.5 the previous output so 0.75. Piercing increases to instantly piercing carapace and two thirds into astartes plate et cetera. Toughness lightly boosted so it can take a 50 bmg before shattering and a slice or two from power weapons
Ukaku: From 308 to 300 RUM (4100 joules), firerate increased to 1.2 from 1 rate of a submachine gun. Capability to utilize it more without tiring.
