Converting Dungeon and Dragons Modifiers to AGE Ability Scores
Use this chart to convert between Dungeon and Dragons ability modifiers and AGE ability scores. Since each system uses different dice and those dice affect tests we need to compare then with their change to succeed. You can see that the 50% lines up with both systems with TN11 which is why I centered the table that way. Both raw D20 and 3d6 rolls are included as that is the base comparison. Then we can calculated the modifiers for each: DnD is "=ROUNDDOWN(F5/2,0)-5" AGE is ""=G5-11" The mapping between the two systems isn't a one to one relationship because DnD has extra rows as compared to AGE. We need to look up both directions matching against the percentage to get the best results going both ways. You can see it does matter that DnD does a divide by two as there are several rolls that match better with the lower versus the higher. The only massaging needed is to round the AGE% to the nearest multiple of 5 percent. This is done since 95.4% and 4.6% are c...
