Shadow of the Republic
Determining Ability Scores:
Roll 4d6 drop one die (probably the lowest, but I’m not judging) and add it up, do this six times. If you don’t like your roll take the default array 15, 14, 13, 12, 10, 8.
You can roll your HP normally (d?+con), if you don’t like that you can take the default value as per your class.
About Art Objects/Gems
You can always “haggle” up (or down) the cost of an art object/gem, which will increase (or decrease) the cost by as much as 50%. You can also trade trade an art object/gem for a similar priced item; for example a 50gp gem could be traded for a riding horse at 75gp (within the 50% increase). So don’t automatically change them for gold.
