Harry Potter and the Half Blood Prince
Crest Locations

Introduction
On Hogwarts, there are a total of 150 crests to collect. 
25 of those you get by collecting mini-crests.  
You need a total of 25000 mini crests. 
You can get these crests by casting Depulso on glowing objects. 
The other 125 crests are hidden on Hogwarts and for you to find. 
I am trying my best to describe the locations. 

There are several ways to collect crests:
#	Some are lying on the ground. Just walk over them.
#	Some are out of reach but visible. 
	Cast Wingardium Leviosa.
#	Some are on a plateau on the wall or are hold by a statue. 
	Cast Wingardium Leviosa on a nearby object, 	
	like a bench or flowerpot, and knock them of there position.
#	Some lay broken  on the floor. Cast Reparo.
#	Some are stuck in or behind a plant. 
	Cast Incendio to set them free.
#	Some are behind a gate. Cast Depulso to break them. 
	Then Wingardium Leviosa to get them through the gate. 
	Then Reparo to fix them.
#	Some are behind a spider web. 
	Cast Incendio on the web and Wingardium Leviosa on the crest.

There are also lion statues who are holding a crest. You have to 
complete a sort of mini quest to set it free. This can be a duel or 
making a potion. There are 10 of these lion statues to find.

There are also specific banners hanging from the ceiling. You have to 
hit these banners, a couple on a row, to  release the crest. 
There are 5 of these banner runs.

Then there are firework boxes. Set them of with Incedio to release 
the crest. Then cast Reparo to fix it. There are 5 firework boxes to find.
