She’s got a limited selection, but the mosses she sells are invaluable when dealing with poison and bleeding. In the aqueduct, you’ll meet the female Undead Merchant. Once he’s freed, Griggs will head to Firelink Shrine where he’ll sell you sorceries and sorcery accessories.

Further along the corridor, you can find the black leather Thief Armor set. If you purchased the Residence Key from the Undead Merchant in (upper) Undead Burg, you can unlock the room where Griggs of Vinheim is held, where you can also find the Sorcerer Armor Set. There are several useful items along this corridor and a couple of new armor sets. The area’s boss, the Capra Demon, is a brutal fight in a confined space (and there are two Undead Attack Dogs in there as well). The Undead Attack Dogs and Hollow Thieves are fast, nimble enemies that deal extra poison damage. It’s a really straight(forward) area, but the enemies still pose quite a challenge.

Lower Undead Burg is a transitional area that moves you from the main (upper) area of Undead Burg to The Depths.
