Collect 11 Silvery Claws and 1 Irontree Heart for Eridan Bluewind in Felwood.
I do not know the one you speak of, [player].
But worry not; if your friend was on a journey to find me, I do know what it was he desired.
In the heart of Un'Goro Crater dwells evil of the purest form. This evil takes the shape of an elemental called Blazerunner... protected by an aura that none can dispel...
None... except those with enough power to do so. I can teach you of this power, [player].
First, do as I ask. Collect 11 Silvery Claws and 1 Irontree Heart from the creatures in Felwood, then return.
