Harry Potter and the Half-Blood Prince
Massive Amounts of Mini-Crests:
———————————————-
Submitted by: RM
You can get MASSIVE amounts of Mini-Crests, however you can only get
it the one time only, and that’s only when you have used the Luck
Potion and are making your way to Herbology. At this point, every
time you use Diffindo to get the Mini-Crests to appear, you’ll get
the full amount of Minicrests available (due to your luck). You should
at this point get as much of it as possible, to make the 25,000 pieces
that you need an easier target to reach.
Winning Duels Easily:
——————————-
You can QUICKLY and easy dispatch ALL enemies by following this three
step combo:
* Use Expelliarmus to knock them down
* Charge up your Stupefy, whilst getting that charged, walk RIGHT NEXT
  TO the person you’re duelling against.
* Fire your charged up Stupefy for a OHK.
This has worked each and every time, and can give you 5 stars for the
challenge VERY VERY QUICKLY & EASILY
