Part 11

Enter the Bloodfly Den, marked by 'Seized!' and 'Condemned' banners. A corpse hanging from an open window provides entry (referred to as 1F).

Inside, you'll encounter bloodflies. Destroy their red nests to prevent reinforcements. Incendiary bolts and flammable bottles are effective. Destroying nests does not count as kills.

1F: Collect four coins under the active bloodfly nest in the barroom. In the quarters beyond the serving counter, find coins on a desk, a lucky sphalerite on a shelf above the bed, and blood amber in the second nest. A corpse in the nearby stairwell has 30 coins.

2F: The stairwell has a nest with blood amber. Two nests in the flat do not contain blood amber but are near a bonecharm, whale oil, and tyvian ore. Use the stairwell's box of liquor to ignite nests without using ammo or health. Incendiary bolts are also in the closet.

3F: The stairwell is blocked. Enter the "three-corpse room" and collect a pouch near the suitcase and an ivory scrimshaw on the floor near a wall breach. This leads to the "piano room" apartment. The stairway nest has blood amber, and the bedroom has pied avocet feathers. Unlock the barred door from this side if planning to exit this building this way.

4F: Locate the piano room's piano and find a stopped-up doorway past the sofa. This leads to another apartment guarded by a nest keeper NPC. These enemies spawn bloodflies and are resilient to gunfire; use sleep darts or fire. Their defeat counts as kills. Collect the husk on the bathroom counter and the black market key in the bedside display case.

From the nest keeper room, you can smash the shutters and use Blink/Far Reach to shortcut to ground level.

OPTIONAL: ROB THE BLACK MARKET: Use the black market key to enter the storehouse via Mindy's lounge. Collect loot from the table and display shutters. Do not alert the shopkeeper or Mindy, as this will close the market for the mission. To rob the cash register without being detected, crouch at ground level and inspect the till to take coins piecemeal.

Robbing any shop earns the "Black Market Burglar" trophy. Robbing more than one shop will prevent earning the "Songs of Serkonos" trophy later.

You can start the next section in the bloodfly apartment's 2F piano room, or proceed up the black market's street.
