When starting a new role playing game or when the players reach a major milestone in the story, they can be treated with a “Goodiebag”, which unique to their character.
Below you will find 8 options to make your character more interesting and detailed. Personally I would recommend using all options at the same time, since they are easy to implement and they provide interesting story tools for your character, by creating keywords for him/her/it and rewards you for acting out the personality and background of your character.
These options can be chosen individually, but some of them work better when combined. By including them all you will see, that they compliment each other, since each option covers different aspects of your character.
The 4 Sentence Tool is a quick way to describe a NPCs personality in greater detail using the 4 sentences: Fascinated by, Seduced by, Offended by and Frightened by.
Knowing more about your NPC's personality and behavioral patterns as a GM, makes it easier for you to interact with the players and create memorable NPCs.
