Grim-slayer

Defeat 100 Grims in Forochel.

Lestache of the LoTRO forums says "The little path up to the Guaradain Sorcerer is the only spot I've found with consistent grims. There should be 5-6 on that path. I'd highly suggest reading a book or doing something else while you kill them, though - they don't respawn fast enough for you to be constantly fighting."

The Gauredain believe that the Grims are the wandering souls of those among their people who were cast out for their cowardice, damned to eternally wander the frozen snow-fields after they froze to death in the ice. Those few among the wise who know of these creatures, however, suspect that they are more likely fell spirits left wandering the northern wastes long after the fall of their ancient Dark Lord.
