Quoting weeble1, reply 1Once you purchase a favor item, that item remains unlocked for the rest of your career in future games. Getting that same favor item in any future game is free...but keep in mind you can only ever have one favor item in a game.
That means if you equip an unlocked favor item, you have to wait until the next game to unlock a different item.
but when i unlock an item..do i have to re-acculimate the pts from what i had before minus what i spent to unlock
Once you've unlocked that item, you can use it in any future games without spending further favor points. However the points spent to unlock it are 'lost', and need to be reaccumulated to buy another item.
Example: You have 550 points, and at the beggining of game 1, you spend 250 points to unlock the Brilliant Bauble. You now have 300 points remaining. You win game 1, and get 110 additional points, brining you up to 410. Game 2, you decide to use the bauble again. No further points are spent, so upon winning Game 2for another 125 points, you now have 535 points. Game 3, you decide to buy the Swift Anklet. That brings you down to 85 points. Make sense?
