I will throw a bunch player driven content ideas in the forum, here it goes:
Bounty Hunter kills someone, if it's a corrupted or enemy of the state or any special human enemy and not just a random purple... then the Bounty Hunter could loot a skull.
Skulls should be tradeable.
The skull should be a material for crafting furniture,




Maybe skulls could be also material for decorating ships or spells or quests.
