Utgarde Pinnacle for loving charms

[Azraeil]

The third boss Skadi the Ruthless is based on script where the adds will spawn until you dismount him.
Just make sure to not die while you are killing his adds.
If you do this on heroic there is a low chance for his mount to drop so you have nothing to lose.

the mobs spawn pretty slow though, only the initial group shows decent results ..... but it's an OK place

[OverLordErIcH]

How do you know they drop it? screenshots? wowhead link?

doesnt work getting only grisly trophies

[swankboss]

Two adds spawn every 20 seconds. This is a very slow place.

if you haven't gotten your grisly trophy quota yet, you'll first get trophies untill the quota (250?) is reached, after that you'll start getting the charms
