Optional Rules for BioWare and Magic

These are optional rules to more realistically determine magic loss for
magic users who have had bioware installed. Please remember, though, that
the maximum amount of bioware you can install is equal to you unaltered Body
score.

Type            Compatibility   Mag. Loss

Cultured        100%              10%
Clonal          100%              20%
Base Type O     90%               30%
Type G          75%               45%
Second Hand     3d6 x 5%          See Below

Magic Loss refers to the percentage of the Body Cost of the item that is
also subtracted from total Magic.

Forced Growth bioware has its magic loss determined in the following manner:

Subtract the compatibility of the grown part from 100% and then add 25%.
Multiply the body cost by this percentage to determine the magic loss.

Second Hand magic loss is determined as follows:

Subtract the combatibility rating from 100%, add 35%. Multiply the body cost
by this number to determine the magic lost (yes, this number can exceed the
original body cost).

Example A:

Merlin wants to get an Adrenal Pump (level 2) installed. He checks his
wallet and determines he has enough Nuyen to get a cloned unit. The total
body cost will be 2.50, and his magic cost will be .50 (2.50 x 20%). He also
has to shell 200,000 nuyen out to some street doc.

Example B:

Merlin has come into a second hand Suprathyroid Gland (I don't think you
want to know how). He finds a street doc to install it. The GM rolls a 5 for
compatibility (25%) compatible. Thus, the total magic cost will be 1.54 (1.4
x 110%).

Do not forget that rolls must be made when the surgery is performed to
determine if there is any additional essence loss. Also remember that the
total magic loss for both cyberware and bioware by result from adding both
together.
