I know there are a number of Knowledge Skills listed in the book, and they correspond to the Character sheet.
But there is also a box for Other. I assume for your own ideas.
Would you say it would be out if line, when my Mechanic tries to apply Modifications to weapons, to give him a Setback Dice, because he is an Engineer... not a Weaponsmith?
And allow him the chance to pick up the skill at some point?
Would I then have to grant him Boost dies as he improves his knowledge in this area?
The same could be applied to Armour, Droidsmithing, and other more focused engineering fields?
Is this being too harsh?
