Each species has a unique body chemistry and will thus have a unique reaction to the various body modifications available in the setting. Certain species have a tendency to reject foreign objects such as cybernetics or tissue grafts due to powerful and exclusive regenerative capabilities, while those with overzealous immune systems will have a tendency to reject bloodborne nanomachine cultures and symbiotic entities.
A species' ability to utilize certain kinds of augmentation or treatment are shown by their “Receptiveness Factor” in the chart below.
|Perfect||This species has specifically evolved or engineered itself to be perfectly adapted to the usage of this type of augmentation or treatment.|
|High||This species has a naturally high level of tolerance to this type of augmentation or treatment.|
|Average||This species has a good level of tolerance and/or resistance to this type of augmentation or treatment, but may not experience ideal results.|
|Low||This species has a slight resistance to this type of augmentation or treatment and has significantly lower success rates with this type of augmentation or treatment.|
|Critical||This species has a high resistance to this type of augmentation or treatment, which may result in highly-negative or highly-reduced reactions to this type of augmentation or treatment.|
|None/Immune||This species is entirely unable to use this augmentation or treatment and/or will naturally reject any attempt at tampering via this means.|
