So, I want to add a Perk as part of an inside joke to my game that, upon being selected, would give you a random item in the game every, say, 12, or 24 hours. What would be the best way of going about this? I have very little scripting experience, which is why I'm asking here.

Any idea?

I would check the script that runs on freeside; when you have a good reputation a member of the kings runs up to you and gives you some random consumable. This happens every few minutes though there are fixes that have the script run once per day.
