So I am toying with that idea for some years now, of a necromancer that uses his/her knowledge of anatomy to treat diseases like a modern medic (after all wizards are the closest thing to a scientist in a D&D/Fantasy setting), with concepts like aseptic conditions, immunization, infections and so on.
One of the ideas that I had is of a high level spell that would allow for the transplant of organs and body parts and I envisioned that different races would receive different bonuses/penalties/modifications of their abilities based on the "donor" of the organ. Like a human would receive different bonus/penalties if he receives the heart of Dwarf or and Elf;
The main problem for me (and thus I am here seeking feedback) is what bonus/penalty/modification each organ/body part would confer to the recipient based on the donor of the organ/body part.
Here is an example of what I mean
Arms Transplant
Recipient/Donor Human Elf Half-Elf Dwarf Halfling Gnome Orc Half-Orc
Human N/A -1 STR - +1 STR -2 STR -2 STR +2 STR +1 STR
Elf -1 STR N/A - -1 STR -2 STR -2 STR +1 STR -
Half-Elf - - N/A - -1 STR -1 STR +1 STR -
Dwarf -1 STR -1 STR - N/A -2 STR -2 STR +2 STR +1 STR
Halfling -2 STR -2 STR -1 STR -2 STR N/A -1 STR -1 STR -1 STR
Gnome -2 STR -2 STR -1 STR -2 STR -1 STR N/A -1 STR -1 STR
Orc +2 STR +1 STR +1 STR +2 STR -1 STR -1 STR N/A +1 STR
Half-Orc +1 STR - - +1 STR -1 STR -1 STR +1 STR N/A
This is just an example of how the table would looks like but I need you guys help to create the remaining tables for those organs/body parts
Eyes
Ears
Lungs
Throat
Heart
Liver
Pancreas
Kidney
Arms
Hands
Legs
Feet
Any feedback and help is apreciated
