Stat Conversion – 1d100 to Powered by the Apocalypse

If you’re interested in running oldschool characters in a PbtA system, or using PbtA moves in a d100-based game, you need a way to convert stats and moves between the two systems. Here is my 1d100 to PbtA Stats conversion table…

1d100		AW10		 AW7
01-03	 = 	-2	 = 	-5
04-09	 = 	-1	 = 	-4
10-17	 = 	+0	 = 	-3
18-28	 = 	+1	 = 	-2
29-42	 = 	+2	 = 	-1
43-59	 = 	+3	 = 	+0
60-73	 = 	+4	 = 	+1
74-84	 = 	+5	 = 	+2
85-92	 = 	+6	 = 	+3
93-98	 = 	+7	 = 	+4
99-00	 = 	+8	 = 	+5

So…

  • If you have a % skill score between 29 and 42 (inclusive), that translates to a +2 on 2d6 where 10 = success.
  • +4 is the highest (and -2 the lowest) you typically see in AW, but I included higher and lower mods just because.
  • If you have a +2 in AW terms, this is the same as saying “roll 42 or lower on 1d100” (for a Full Success).
  • Note that the row for partial success (AW7) is always 3 rows down from full success (AW10).
  • The numbers are very close to accurate; the margin of error in this 3-row-jump is only +/- 1% in the worst cases.

    How to use this:

    To import a 1d100 skill/stat into an AW game:

    • Consult the row for your 1d100 %score and look under the AW10 column. This is your AW mod for that roll.

    Example: A PC with a %score of 42 would have a +2 mod for that skill/stat in an AW game.

    To import a 1d100 action resolution roll into an AW game:

    • Consult the rows for your AW Stat under the AW10 column (Full Success) and the AW7 column (Partial). The high-end of the range shown is the number you must roll lower than.

    Example: A PC with a +2 needs to roll below 42 for Full Success, and anything from there to 84 is a Partial Success.

    To import an AW move into a 1d100 game:

    • Hitting your %score or lower is a Full Success (10+);
      hitting within 3 rows down from there is a Partial Success (7-9).

    Example: A PC with a %score of 42 needs to roll below 42 (ie hit on their score) for Full Success (10+ result), and anything from there to 84 (3 rows down) is a Partial Success (7-9 result).
