Working Undercover

Dem humies got some pointy stabbas wot we can use for da Waaagh!, but dey was smart and hired a bunch o' dem Ogre big-uns t' keep dem safe. If we is goin' t' get dose pointy stabbas, we is goin' t' need t' get past dem Ogres first. An' if we is gonna do dat, we is goin' t' have t' be sneaky! Wot we need is some stunty metal fings dat'll make you look like a stunty! Why!? I thought dey said youse was a smart one! It's 'cause stunties and humies is always friends, dat's why! Dis is me best idea ever! I spotted some stunties near da pass. Kill one o' dem and take 'is metal clothes. Dat'll make you like a stunty and you'll trick dem humies for sure!

Head to the south where there are Oathbearer Rangers hiding in the pass. Find Ranger Stoutfoot and kill him for his helm. Examine the helm and attempt to put it on.
