Whenever I buy a rare item, the points doesn't show up on my trophy. How many rs points would I need to have it show up on my trophy? So far I have 4rs points.

Usually it's just the cache. Your points will appear in a few minutes, as they do now.

Oh. Thanks ^^ So the points will not appear on my profile?

Oh well on your profile then I have no idea. I assumed by trophy you meant the forum trophy.
