For information on the Loser Legacy, created by MiaAngelina, you can read them over at MTS.
The rollers were created using Wheel Decide. The first wheel is for the fatal flaw, the second wheel is for the allowed traits.
Fatal Flaw Spinner
TEEN & UP ALLOWED TRAITS: Note you'll need to spin for each trait individually, and re-spin if you get a duplicate trait.
BABY ALLOWED TRAITS: This wheel contains the short list of un-modded game allowed loser traits at time of birth in game. I won't be making a wheel for child traits, because when a sim ages to child is the first chance you get to add the required Loser trait.
