Crystal Claws. The cyberspawn's claws are monofilament in nature – they ignore all non-force-based armour and attack against 10+DEX of the target.
Skewer. On a critical hit, no more than once per turn, when the cyberspawn makes a melee attack with its crystal claws and hits, the target takes an extra 10 ( 3d6 ) damage and the cyberspawn gains temporary hit points equal to the extra damage dealt.
Cyber-Interface. Cyberspawn can interface with any Arcana to manipulate, fix, or use it in another way. When doing this, he has advantage on Intelligence (Arcana) checks.
Multiattack. The cyberspawn makes two crystal claw attacks. When rolled he will also make one Back-Mounted Disintegrator attack.
Crystal Claws. Melee Weapon Attack: 1d20+9 to hit vs. DEX, reach 5 ft., one target. Hit: 25 ( 7d6+4 ) slashing damage.
Back-Mounted Disintegrator (Natural 15+). The cyberspawn chooses a target he can see withing 150 feet and a thin green ray springs from his back mounted distinegrator. A creature targeted by this spell must make a DEX saving throw. On a failed save, the target takes 10d6+40 force damage or half on a success. The target is disintegrated if this damage leaves it with 0 hit points. It otherwise acts as the disintegrate spell.
The cyberspawn becomes invisible until it attacks.
Cyberspawn are the remnants of an alien species. After exhausting the supply of natural resources on their home planet, the aliens in an effort to simply survive used psychocoders to download their personalities to a series of autonomous robots programmed to scour your nearby worlds for useable resources. As time passed, the aliens grew weaker and sicker – and evermore depended on the robots for survival – but they never curbed their mass consumption of resources. The robots had to venture farther and farther from the home planet to find useable resources. As the aliens became weaker and more desperate, they programmed each new generation of robots to be more and more aggressive. Now the latest generation, the cyberspawn, move from world to world in massive war freighters, taking whatever they want and killing anyone who gets in the way.
