A Collection Worthy of Xilebo

Oto wants you to get 10 Crack Chafer Helmets (quest item). You can find Markschafers in the Cemetery of the Tortured, and in "Bonta's Cemetary"

Killing Markschafers is no easy task, you may want to bring some high lvl friends to fight with you, since they're usually in big mobs with other markschafers.
