Looks like it's time for an intelligence check! rattle rattle Got it! Checking my languages, it looks like I can speak Elder Expression! This long forgotten language includes such constructs as "Ye Olde Ternary" and "Mathematical Verbisms!"
So, open ye olde scroll of Character Definition and include in this most ancient and prescient of documents an additional line item of type
Calculation of the
Numberic nomenclature. Append the Lay of Expressive Renown:
=Strength > 11 ? Math.Floor((Strength - 10) / 2) : 0
Failing that, the lost Ternary of Tho'mas can be used for more finite control:
=(Strength = 12 Or Strength = 13) ? 1 : (Strength = 14 Or Strength = 15) ? 2 :...
But beware, along that path lies much danger and confusion!
