The Black Loch

The Blood Tide's ruthless attack on the Black Loch struck fear into the local inhabitants. {{Quest | name         = The Black Loch | adpack       = Sentinels of Stormreach | level        = 7 | duration     = Medium | solo         = 1279 | normal       = 2268 | hard         = 2404 | elite        = 2539 | ecasual      = 6660 | enormal      = 11486 | ehard        = 11873 | eelite       = 12259 | loc          = The Black Loch | bestower     = Tyn d'Deneith | npc          = Tyn d'Deneith | zone         = House Deneith | patron       = House Deneith | favor        = 4 | epic         = 20 | mappic       = M black loch.png | maplegend    = yes | loadingpic   = Questloading TheBlackLoch.jpg | free            = VIP | overview     = After the Blood Tide invaded the Black Loch the local residents hired House Deneith to drive the Blood Tide out.

 * Spawning/respawning monsters
 * Spike trap just past the first shrine; control panel is on the wall to the south, in the center of the trap. The trap *can* be timed to run through, avoiding damage.
 * A falling rocks trap so weak that most people don't even notice
 * The four keys are each guarded by one of Dheren Kiettuc's apprentices and several zombies
 * The Green Key is in the east-most passage
 * The Red Key is in the south lobe of the passage north of the spike traps
 * The Blue Key is in the western end of the southwest passage
 * The Jeweled Key is in the eastern end of the same passage; this time, the apprentice is surrounded by living pirates, not undead ones
 * With enough jump, it's possible to swim to the walkway by the ship and jump/climb up, bypassing the Blue and Jeweled Doors entirely; however, you still have to (eventually) go through them. It's a good shortcut for those wishing to simply get the Gold Key
 * Due to the unique nature of the Undead in this quest, they can be manipulated with Intimidate, Bluff, and Diplomacy although it will not trigger sneak attacks.
 * Despite coming across Failed Experiments earlier in the quest, you don't get the Optional to kill them until you stand on the pedestal in the Zombie Pen, in the northwest corner; the earlier Experiments don't count towards the 20.
 * The Vault is in the westernmost room; the Gold Key is obtained after the fight with Dheren Kiettuc.
 * The Black Loch's Captain may appear with the reinforcement guarding the Vault (very rare).
