Knowledge of how alien lifeforms evolve, interact, and adapt across different environments—vital for identifying, interpreting, or predicting alien biology.
Roll d100 + your Astrobiology skill against DR 100.
Success: You identify a creature’s biological structure, environment compatibility, and behavior patterns. This may inform diplomacy, combat tactics, or medical intervention.
When used with the tech modules in the category Biotech Boosters or Venom Infusion Frameworks a success will allow you to use these drugs on creatures they are not normally designed for.
+ 20 DR — You are in combat with the creature.
+ 20 DR — Alien species is completely undocumented or classified
+10 DR — Target lifeform is bio-modified, mutated, or hosts symbiotic systems
+10 DR — You are under time pressure or lacking equipment
–10 DR — Species has known biological parallels (e.g., close to known mammals)
–10 DR — Long study period or access to lab/medical data
You dissect a xeno-predator corpse from a jungle moon. Its dual stomachs and layered carapace suggest resistance to acidic environments. You roll Astrobiology to determine if it’s vulnerable to energy-based attacks. With plenty of time at hand you roll against DR 100.
Astrobiology is the study of non-Earth lifeforms across the galaxy. It blends evolutionary theory, comparative physiology, and alien ecology to interpret life that may function on entirely different principles than known biology. Whether faced with a crystalline lifeform that metabolizes radiation, or a gelatinous organism that communicates chemically, this skill allows a character to identify survival traits, exploit weaknesses, or offer informed responses to unknown beings. It's invaluable for exploration, diplomacy with non-humanoids, interspecies medical research, and combat adaptation.
Not optimized for sequencing, but supports a lot of skills such as medicine skills and some academic skills (Alien Lore).
