Be warned that by completing this particular line of quests you will be unable to complete any further quests for the city guard in the city of Amaranthine. You must have the ‘Awakening’ DLC installed which can be accessed at any point from the main menu. When you first arrive in the city of Amaranthine and before entering the main gate you will notice a ‘shady character’ running around frantically. He will ask you to go speak to the bartender at the tavern ‘The crown and lion’ and persuade him to clear a passage which is currently blocked. You must be strong in Coercion & cunning to persuade or intimidate the bartender effectively into clearing the passage. Once you have done this you must return to the ‘shady character’ and choose the conversation which says “Anything else you need from me?” He will then inform you that a group of thieves have been having a negative effect on the profits of the smugglers and explains that they have attempted to run them off but have been unsuccessful in doing so. Eventually he will ask if you could help find a more permanent solution to which you should choose the option that says “you mean kill them." Next he tells you that he has arranged for his associate to meet with you inside the den of thieves to help you clear them out; you must then go to the den which is nearby and clear out them out with relative ease. Once this is done it will then become possible to take advantage of the glitch which will grant you exactly 15 sovereigns every 5 seconds or so. You will also gain a small amount of experience for each member of your party.
Speak with the smuggler leader and he will reward you with the 15 sovereigns; choose option 3 (is there anything else I can do). He will then ask you to kill the lieutenant in charge of the city guard to which you must respond with option 3 again (I can’t do this). You can now continuously do this over and over until you become insanely rich along with leveling up fairly quickly at the same time. I managed to generate around 100 sovereigns every 30 seconds as well as going up 2 tenths of a level at the same time. You could just never accept his request to kill the lieutenant and return to him whenever you need an injection of money as completing the quest line isn’t very important in terms of completing the DLC successfully. Make sure you save before speaking to the smuggler leader as well as during the process of the glitch just in case you choose the wrong speech option.
