The Dungeon Under City of Kil-le-mall Pitch

​This campaign is literally just one giant dungeon filled with enough baddies and loot to bring a group of 4 PCs from level 1 to level 20 and beyond.
The city of Kil-le-mall is famous for it's mud, which once hardened is nearly indestructible and only becomes harder over time. Unfortunately, the city is also slowly sinking into said mud. It sinks very slowly, only a couple inches per year, but since it's been sinking for over 1000 years the residents have had to compensate by building new floors above the existing buildings and roads. As a result, there is a vast under city. As is only natural, the under city is filled with every kind of monster known to man, and several that aren't known. Not to worry though, the under city is fairly well sealed off from the city proper, and there are very few connections between levels since the city liked to start with a brand new flat ground each rebuilding.
 * Freedom of Choice: 1/5
 * Combat Focus: 5/5
 * Levels: 1-20

The only people forced to deal with the under city are those charged with a capital crime like murder, horse-theft, or urinating on the king's prize rose bushes. Those poor souls are cast into the under city, and just for good measure the grand wizard curses them to be unable to leave while a single monster still crawls in the cities depths. To help them in this impossible task, the city equips felons with a few weapons and tools and the high priest gives them the gift of Adrenaline (+5ft walking speed, +1 to initiative, never suffer exhaustion from lack of sleep. Side effects include: unable to take a short rest except immediately following a fight, unable to take a long rest without Magical Incense of Sleeping Tight or MIST).

''Create a level one character and describe your crime (or at least the one you were found guilty of). Add Adrenaline to your effects, and 1 MIST to your equipment.''
