There are some pieces of any dungeon that you go inside that makes your adventure frustrating, to say the least. The question being is, which portions of a dungeon is the hardest for you to overcome in your opinion?
I'll explain the choices:
Just going through it - You're having trouble navigating the maze of rooms & hallways.
Fighting other guys - self-explanatory
The trap-infested rooms - Those are the rooms that have you finding traps left & right, & in a row.
Monster houses - self-explanatory
The boss fights - also self-explanatory
The gang fights - Those are the boss fights that have you fighting an entire squad of people.
So that's it, all you need to do is keep all of this in mind when you're casting your decisions.
