Hrotha will forge a weapon of might and glory for you, with the right components.
'So, the spear...your weapons are good enough for a vagabond warrior, but we wardens deserve the finest of spears, do we not, ${PLAYER}? Yes, I believe we do. Otherwise we might as well be Dunlending rabble jabbing at things with pointed sticks!
'Then let us make one for you, shall we? Yes, a spear that befits someone of your repute. Then the minstrels might sing about it as well as you!
'It means work for you, of course. I cannot do it all myself, after all, and nor should I! Bring me the breastplates of the Angmarim who swarm upon Annúminas and the spear of the Gauradan Bryok in Forochel. Go on now, ${PLAYER}...the Enemy will not wait while you dawdle!'
Angmarim can be found at Annúminas in Evendim. Bryok dwells in Forochel.
Hrotha wishes you to bring the breastplates from the Angmarim invaders in Annúminas and the spear of Bryok the Gauradan.
Wights can be found in Angmar, Forochel, Annúminas, and Helegrod. Cave-claws can be found in Angmar and Sarnúr in Ered Luin.
Hrotha requires the remains of wights and the talons of a like number of Gorothlad cave-claws.
Gríshakrum, Kughûrz, and Dafrim may be found at Urugarth. Barashal dwells in Carn Dûm.
Hrotha needs a tally-stick from the Orcs of the Ongbúrz and the horn of Barashal the Gorthorog.
