Guild Wars 2

Can I still use them in the future to get more MF? And what will happen with the 24 hours buff from the one item I used already? I hope this won’t be usless next week… I don’t think I’ll play enough to get all the hours left used until next week.

The MF buff has nothing to do with the changes to MF.

The problem is that there was MF as a stat on armor and weapons. That’s what will be changing. Your buffs will work fine.
