Cyborgs are alien machines built to perform difficult (often suicidal) tasks that are best performed by a human. They appear to be exceptionally tall and well-built male humans, indistinguishable from normal human beings. But their flesh was grown over a duralloy skeleton in big biotanks. And, while all of their organs, except for some sense organs, are tank-grown from cell clones, most have special electrical or computer augmentation (a tiny pacesetter that can be used to push the heart to extreme exertion, for example).
A set of computer chips in the brain accept programming beamed to the cyborg via any standard communications device. Thanks to a special hardware feature, cyborgs will even accept self-destruct programming that stops their heart. All programming must be in a special code. Like the aliens who made them, cyborgs have a mastoid implant that allows them to use the alien communications network at any time.
Cyborgs have infravision at a range of 60 feet and can breathe underwater. They can be harmed only by magic or magic weapons, but are immune to sleep, charm, and hold spells. In addition, experimental Class IV cyborgs have some special characteristics. First, they use the AC, Hit Dice and Save values listed above after the slash; all other cyborgs use the values before the slash. Second, the range and acuity of their vision, smell, and hearing is four times the human norm. As a consequence, they can't be surprised.
Cyborg programming normally prevents them from harming humans or humanoids (including aliens). However, there exist illegal programs that can circumvent the safeguards built into the cyborgs at the factory. Using these, it is possible to modify an existing cyborg so that it becomes a cyborg terminator, a superlative killing machine feared throughout the galaxy. So acute is Riesling's paranoia that he has used bootleg versions of these programs to turn all of Beagle's cyborgs into terminators despite the fact that this act is a Federation capital offense.
Cyborgs always carry 1-4 alien devices (treat as magical treasure).
The adventure also includes statblocks for the Class IV cyborg as follows:
Cyborgs (2): AC -1; HD 22; hp 88 each; #AT 1; D 3-30 (fist) or 6-36 (hand blaster) or special (grenade launcher): MV 120ʹ (80ʹ); Save F16; ML 12; AL N; XP 2,750. These are Class IV terminators. Unlike the crewmen and robots the PCs meet, the cyborgs take no prisoners. They simply kill any unauthorized personnel they encounter.
Here's the Cyborg in DA2 for comparison. Weebak's 20 Hit Dice indicates that "he" is a standard cyborg.
Weewak: AC 0; HD 20; hp 8; MV 120ʹ (80ʹ); #AT 1 fist or weapon; D 3-30 (fist) or 6-36 (hand blaster); Save F10; ML 12; AL N; XP 2,000. Weewak carries a blaster with a spare power pack. He has infravision, and can also breathe underwater. He can be harmed only by magic or magic weapons, but is immune to sleep, charm, control, and hold spells.
Since the Class IV Cyborgs in DA3 have 4 hit points per Hit Die it seems reasonable to presume that so do standard cyborgs, meaning that Weewak's stat block is simply missing a 0 and he should have 80 hit points.
Alternatively, he actually does only have 8 hit points - maybe he's badly damaged and needs high tech science to be repaired? Or if cure spells work on cyborgs, maybe he Weewak doesn't want to go to a cleric as that would expose him as a cyborg?
Being damaged down to 8 hit points might help explain why he thinks the PCs could help him on his mission to destroy the mutineers and all their tech by blowing up the temple. If he can be destroyed by a single blaster hit he'd be reluctant to just charge in and start slaughtering them.
EDIT: I forgot to mention Norn, the other cyborg in DA2 who's guardian Saint Stephen's room. He has identical stats to Weewak.
