NPC resource - would you like one?

We've all been there. You/ve carefully planned your campaign, maps, characters and items... Then one of your players decides to stop into a random shop and expects a fleshed-an out NPC on the spot.

This is how you end up with towns of guards named Bob.

I'm thinking of making a helpful chart!

It would include:

• A number so you can roll
• Their occupation
• Name
• Appearance
• Personality
• Guide to how they would react if the bard attempts to seduce
• An additional mystery/detail/quest lead they can uncover with investigation/diplomacy/intimidation check
• Items your party may get from them
  

Would you find such an item useful? What else would you like to be included on the chart?

Thanks for sharing your opinion!
