Frump
Frump lives in The Boardroom at the end of Frump's Misfortune. This particular dungeon map contains bodyguards for Frump who are stronger than Frump himself! Luckily we'll fight Frump alone in the end.
A magical barrier has to be broken so Crypolyn Kaptcher can be released, a giant spider which comes with alot of support fodder. Some of the Banshees included can cast the power Fear onto you, so if you have access to the skill Banner of Bravery you'll have some defense against it. Once Crypolyn here is killed, the second barrier opens even if the other fodder isn't dead yet. If you're not careful you'll be fighting two groups of fodder plus a boss, GorgeNFloss, another giant spider. The second group, however, isn't as tough as the first.
Once the second spider is dead, a door opens and you gain access to Frump's room. Frump is standing behind a chair located behind a table with 5 clickable skeletons that move like they SHOULD drop small piles of gold or items but don't. Frump will move toward you slowly and has some great knockback skills, but does not do much damage. Good use of the skill Monster Bait here can have him bouncing back and forth not knowing which target to hit,or you can use a ranged spell or weapon and try to stay away from his fists. A solo fighter will have a hard time, but if you just stand your ground and get up every time you are knocked down eventually you will wear him out.
Beyond the boardroom are four treasure chests and a one way portal to the The Mutanous Malaise Base Camp.
