1) Adding a Charisma Attribute-There are skills and situations where using IQ is "okay" but a Charisma attribute might be better for character interaction/reaction tests and for some skills.
2) Brace yourself as this one is much more "heretical" --using d20's to resolve tests. As the Blades and Black Magic uses a 3 tiered skill system (Inexperienced/Trained/ Expert) it works well with the bell curve d6 system as written--but could also work with d20 as follows:
- Inexeprienced, roll 2d20, use the highest die roll
- Trained-roll 1d20
- Expert Roll 2d20, use lowest die roll
Yup I understand and do love the d6 bell curve, and have it as the core mechanic currently but its interesting to see what might be possible using the d20 mechanic.
I would not say this is a Richard Dreyfus "this means something" moment, but I think it is important to look at different possibilities.
As always, appreciate your thoughts
