Cybernetic Enhancements and Bio Augmentations
Cybernetic enhancements and bio augmentations are the most common ways characters in the Cradle push beyond natural human limits. Cybernetics are permanent mechanical or neural prostheses — artificial limbs, subdermal armor, neural interfaces, and weaponized implants — requiring surgical installation. Bio augmentations include temporary pharmacological agents (drugs, serums, nanites) and permanent biological modifications (organ grafts, genetic tweaks, endocrine regulators).
Enhancements add Attribute Modifiers (AtMods), Armor Value (AV), Skill Rank Modifiers (SRMs), Gravity Rating Modifiers (GRM), or special effects, and they count toward encumbrance (Strength × 10 kg carry limit).
Key Integration Rules
- Installation (Cybernetics): Requires successful Medicine Action Roll at Target Number (TN) 18.
- Success: Fully installed and functional.
- Partial Success (TN – 1): Works, but –1 AtMod for 1d6 days until adjusted.
- Failure: Complication (e.g., infection, –1 AtMod permanent until repaired).
- Critical Failure: Implant rejection (remove at TN 21 Medicine or permanent damage).
- Activation (Bio Augmentations): Temporary items activate immediately (no roll). Permanent ones require surgery (same TN 18 Medicine as cybernetics).
- AV & Damage: Cybernetics provide AV (stacks with worn gear, personal max total AV 12). Weaponized cybernetics use personal damage scale (e.g., 1d6 + modifiers; critical hit +1d4). Bio augmentations rarely add AV but may boost Health (HLTH) for effective soak via reduced wound penalties.
Piecemeal (HLTH 17, Base HP 34) has the Adrenal Regulator Implant (+1 HLTH AtMod, raising effective HLTH to 18 and current Max HP to 36). During a brutal boarding action, he takes 19 damage from a vibro-blade strike. Without the implant: Current HP drops to 34 – 19 = 15 (below 50% of his fixed Base HP of 34) → Piecemeal immediately suffers –2 to all Action Rolls. With the implant: Current HP drops to 36 – 19 = 17 (still above 50% of his fixed Base HP of 34) → Piecemeal takes no wound penalty and continues fighting at full capability. The extra 2 HP from the +1 HLTH AtMod effectively kept him out of the penalty zone longer. A follow-up hit of 8 damage drops him to 9 HP → he suffers only the –2 penalty (instead of –5 without the augmentation). The implant gave him two extra rounds of peak performance before wound penalties hit hard — a real, rules-compliant form of “effective soak” through increased resilience rather than armor.
Key Integration Rules
• Installation (Cybernetics): Requires a successful Medicine Action Roll at TN 18.
- Success: Fully installed and functional.
- Partial Success (TN – 1): Works, but –1 AtMod for 1d6 days until adjusted.
- Failure: Complication (e.g., infection, –1 AtMod until repaired).
- Critical Failure: Implant rejection (remove at TN 21 Medicine or suffer permanent damage).
• Activation (Bio Augmentations): Temporary items activate immediately with no roll. Permanent ones require the same TN 18 Medicine surgery as cybernetics.
• AV & Damage: Cybernetics provide AV that stacks with worn gear (personal maximum total AV 12). Weaponized cybernetics use the personal damage scale and core critical hit rules.
• Encumbrance: Cybernetics add weight and count toward the Strength × 10 kg carry limit. Bio augmentations are negligible unless otherwise noted.
• Gravity Rating Interaction: Some enhancements adjust GRM (e.g., +1 in mismatched gravity) or help mitigate penalties.
• Health Points Modifiers: Enhancements increase current Max HP (e.g., +1 HLTH AtMod adds +2 to current Max HP) but do not change the fixed Base HP used for wound penalty thresholds. They may also aid healing or provide temporary HP.
• Psionics & Combat: Fully compatible (e.g., Neural Interface grants +1 SRM to psionic Talents). Weaponized cybernetics use Melee or Ranged Combat SRM as appropriate.
• Costs: Listed in ounces of gold (oz gold) and platinum (oz platinum). Apply local economy modifiers (d6 roll) from the Economics section.
• Drawbacks: All permanent enhancements carry rejection risk (monthly HLTH AR at TN 12–15 or suffer –1 AtMod until repaired) and may trigger social stigma (–2 PER AR if witnessed).
