Since we have diplomacy and slicing helping out our rp skills, i thought there might be others that could do the same. Here's my list and my reason for each.
Treat Injury -- Biochem
Biochem is for the creation of performance-enhancing chemical serums and biological implants in Swtor. If you take it as a broader view though, you could say it would more precise and accurate knowledge of both medical equipment and techniques in general. This would make treating wounds and injury easier and/or more efficient.
Survival -- Bioanalysis
You need knowledge to adapt and survive in the wild. Knowledge of both plants and animals that are both harmful and helpful would do that.
Demolitions -- Armstech
Armstech is for the skill of constructing blasters, blaster rifles and upgrades in swtor. Again, if you take a much broader view, you could say it would include the knowledge of all non-force weapons. This would include mines and bombs which would help immensely for demolition.
Repair -- Cybertech
Droid parts and other equipment can only be made by a cybertech. So it would make sense that someone skilled in it would be able to fix them.
That's all i could think of that would make logical sense. Thanks for reading one man's opinion
