Physiology Modifiers

Physiology Modifiers

The following skills deal with the health, function, or vital points of living beings: Body Language, Diagnosis, First Aid, Physician, Pressure Points, Pressure Secrets, and Surgery. These skills work as written when working with members of your species. When dealing with a member of another species, apply the following modifiers:

Species with similar physiology: -2 (human vs. Elf) to -4 (human vs. troll).

Species with very different physiology, but still from your world: -5. This includes all normal animals.

Utterly alien species: -6 or worse (GM's option).

Machine: No roll possible! These skills do not work at all on creatures with the Machine meta-trait.

A successful roll against a suitable skill lets you avoid these penalties. This roll is usually against the relevant racial specialty of Physiology, although Biology-4 suffices for common animals.
