There is a new tool in early beta at http://tools.notesfrompavis.com/
If you want to design characters relatively quickly Character Skill Designer is there for you to help with the skills part. It (currently) helps to create cultures and careers from the Mythras Core.
It gives the player quick way to design the skill set. In Mythras RAW there is a set of standard and professional skills available per culture and career. Each culture also has different careers available.
So enter the characteristics (Str, Siz, Con etc…) in the tool
So for example if your player has dreamed of being a Nomad Diabolist from Northern Wastes CSD lets him pick Nomad as the culture, Diabolist as a profession. After this tool let’s you select the right amount of professional cultural and career skills (which is max 3).
Next it let’s you see all the skills (including the standard skills that were not available with the culture/profession). The CSD calculates the base percentages for the skills and let’s you sort them by skill% to see how the skills fit players view and where to add cultural or career points.
The skill template has a note for each skill about whether you can use cultural or career points or whether it is just standard. When you are satisfied with the skill combination you can download that as a CSV file.
This will be developed further. There might be some bugs in the combinations, feedback welcome
