Black Market???Follow

I imagine most people have worked out how to use the broker. These guys sell items offered by player merchants at a 20% commission but also provide the information you need to get to the inn room and buy without paying commission

There is also a character who will sell you Freeport goods, popularly believed to be cheaper than the Qeynos market generally is. This guy is a Fence and he is rather hard to find

To reach him first find the broker in Qeynos Harbour. By the broker are some steps leading down into the canal. Go in and swim north. You will have to duck underwater to enter a tunnel and will see the Breath meter appear (for those without water breathing magic). Don't panic, the Fence is perfectly reachable before you run out of breath. Just go north up the tunnel and
soon on your right hand side you'll see a hole. Swim down through the hole then up into the room. Visit the fence and don't neglect the fighter arts (cough). I've some paladin and monk ones but ignoring my obvious self-interest there are genuinely cheaper goods to be found despite the 40% fence surcharge. If you don't want to pay the surcharge trhen try /telling the merchant, not everyone sells afk

If you're at all nervous about this simply get a priest to put an
Enduring Breath spell on you but I found it blind with a fighter without any help when I first looked for it (took about an hour and a half but I didn't have directions)
