Converting d20 over to d20 under?
To clarify, I'm not asking "should" you, but rather if you wanted to how would you do it?
If you were to convert D&D 5E's modifiers and proficiency bonuses (having a DM set DC) -and instead- have a Dragonbane skill-based DC system - how would you go about doing the math?
I was thinking of taking the D&D modifier (average of +2 or +3) adding it to a static value (8?) plus the proficiency modifier (+2? at early levels) to give the player a roll under #?
Thoughts?
