Agree to his offer to give you the 50 Sovereigns needed in exchange for double the return (100 Sovereigns). Go to Lowtown at night time and talk to Dougal Gavorn near the foundries.
Doing Friends in Low Places instead of paying the 50 sovereign will reduce your profits from the Deep Roads Expedition. If you do have 50 Sovereigns available, it is recommended you do not do the quest and instead skip directly to The Deep Roads Expedition Quest.
If you realize you cannot raise enough money (maybe you spent too much on equipment) then this quest is your only way to advance to the next act. This quest is an alternative to raising the 50 Sovereigns needed to pay Bartrand. Go to Gamlen's house, read the letter on your writing desk, and accept the quest. Friends in Low Places This quest becomes available once you have completed at least half of the quests of Act 1.
