Extending this line of thought, I was thinking about about ability points. The current system of raising them seems a little inorganic. A small but mainly aesthetic change would be to change it to a “focus” based system, as in you choose three areas of focus beforehand for your brothers, and these will increase with each level, with focus being interchangeable between levels or at certain points. Another method would be for all abilities to gain a small boost with levelling, with focused abilities gaining a larger percentage.
