Fatal flaw
Fatal Flaw List

A Fatal Flaw is a negative trait. Almost every character in The Sims Medieval has one, but certain quests allow a Sim to convert their fatal flaw into a Legendary Trait. The quest summary will say when a Legendary Trait is available through the quest.

Many of the fatal flaws seem to be loosely connected to the Seven Deadly Sins.

Both adults and children have fatal flaws.
