LORE: after wymar realizes that eggyheads weakness is the sun, she soon discoveres that mr trollface has a strong collection to the sun and eggyhead, so she calls a former slave to trollface named sam and they plan a hiest on trollfaces yacht, his yacht is guarded by henchmen and auto-turrets, its pretty grueling but you can find some really useful weapons like the troll-gun or the MAC-12, after you take hack into the control system and the doors and sneak through the vents to get in the steering deck, you find mr trollface who soon puts the yacht on autopilot and the battle begins, this bossfight is one of the hardest bossfights up to this point, and goes through all 4 of mr trollfaces stages (including his sun beamer stage) and after you defeat him you get 2 items (trollfaces suit and childs drawing)
you also have to steer the yacht to the refugees hideout where the former slaves eventually throw mr trollfaces body in the river and party all night.
Wymar is eventually invited to the slaves party, but she refuses as her next target is eggyhead..
