Editing Four Corners of Dereth (section)

=== Part 4: The Stinging Corner ===
# The [[Stinging Corner]] is located at 95.3s, 89.7w, on [[Singularity Caul]] island.
#* Route: Use [[Singularity Recall]] and then run.
# This dungeon is a true maze. From the start, head right (East). Ignore the little loop in the hall on your left, and take the next left (North) until you arrive at a T intersection.
# Take the left (West) to the corner of the hall, then follow the hall North to another T intersection.
# Head left (West) followed by another immediate left (South).
# Ignore the left turn and proceed West down the hall and down the ramp. At the bottom of the ramp take the right (East).
# Ignore the little loop on your right and take the first actual hall on your right bearing East.
# Take the first hallway on your right and head as far South as you can until the hallway turns. Follow it West and take the first hallway you come to on your left (heading South).
# At the next T intersection head left (East). Ignore the halls on your left and right, and simply follow the hall as far West as you can until it turns North and takes you up a ramp.
# At the top of the ramp take a right (East) followed by a left at the T intersection (West).
# Ignore the turn on your left and instead proceed down the hall as it heads East and then turns South.
# Take the next hallway on your right (East) and follow the hallway South until it takes you down a ramp.
# Talk to the [[Bak'tshay Keeper (Stinging Corner)|Bak'tshay Keeper]] and as he becomes attackable, the door into the room will lock behind you and 3 [[Infectious Rat]]s will also spawn.
#* {{Tip}} Kill the [[Infectious Rat]]s 1st as they chain cast [[Incantation of Fester Other]].
# Defeat the Bak'tshay Keeper.
# Loot a {{Itemlink|Signet Fragment (Stinging Corner)|Signet Fragment}} (drops 9) and head to the next dungeon (if you have not completed them all yet).
# Combine the the [[Signet Fragment (Frozen Recess)]] and [[Signet Fragment (Fiery Alcove)]] to create a [[Combined Signet Fragment]] (1st half)
# Combine the [[Signet Fragment (Stinging Corner)]] and [[Signet Fragment (Charged Niche)]] to create a [[Combined Signet Fragment]] (2nd half)
# Combine the two resulting halves to create the {{Itemlink|Complete Signet}}
# Return the completed signet to [[El'Yst Maggann]] in [[Yanshi]] at 12.0S, 42.6E.  This will flag you to enter the [[Sanctuary of the Recluse]] within the [[Lost City of Neftet]].
#* {{Warning}} The flagging is permanent.  There is no need to repeat the 4 corners dungeons.
