Shadowrun: Dragonfall Cyberware

Cyberware basics

 * All characters start with 6 Essence. Installing cyberware reduces a character's Essence permanently.
 * If you upgrade a piece of cyberware to one that has a lower Essence cost, you do not get the Essence back. Instead, the difference creates an Essence "buffer" that contributes towards any additional cyberware.
 * For magic calculations, Essence is rounded down.
 * Dragonfall adds new cyberware beyond the Basic and Alpha types. All of the Bioware is new in Dragonfall, as well as some without a type listed. Approach Xabier Ezkibel to install your cyberware.

Essense Buffer Example

Written by HBS_Jeff on 2014-01-25

"Here's an example of cyberware installation and upgrading, with the help of Street Samurai Bob:
 * Bob starts out with 6 Essence, he then installs Cybereyes that have an Essence cost of 0.5.
 * Bob now has 5.5 Essence (this means that Bob only uses 5 Essence for magic calculations), he then installs Dermal Plating with an Essence cost of 2.
 * Bob now has 3.5 Essence, he then upgrades to Dermal Plating Alphaware with an Essence cost of 1.
 * Bob still has 3.5 Essence (with a 1 Essence buffer), he then installs a cyberarm with an Essence cost of 1.
 * Bob still has 3.5 Essence (the Essence buffer is filled without changing Bob's Essence).

You can see that Essence never is gained once lost, but is allowed to be filled with cyberware even after upgrading to a lower cost."
