Call Of Shadows
1930's Character Improvement
In the 1930’s era, you often won’t have the time to spend karma based off the timetables for improvement for SR5. So, instead, if you use a skill during the play session, then that will count as the ‘training time’ needed for improving the skill. This is adapted from Call of Cthulhu’s skill improvement.
Attributes can just be bought in karma. You will be running. You will be thinking.
Attributes can also be permanently reduced due to injury or spell, especially charisma, so be cautious with dumping karma into your atts.
