 * 8 Traps: blades, ice, fire and poison (Kobolds can be damaged by the poison trap)
 * {{Bug|The 3 Secret doors, leading to trap Control Panels are already in a revealed state}}.


 * misc       =
 * There are a couple ways to 100% die in this quest. Stay alert.


 * Don't let the red gelatinous cube touch you, or you die. No saving throw allowed.
 * There are some alcoves (some secret) that seem safe – they are, however you must squeeze as far away as possible from any hallway where the ooze is traveling, including through side-walls!

Walk through:
Open first door, talk to Leth, then buff up. Open door, wait for Garko to lower spike barrier. Don't jump down or you die (highly poisonous environment at the moment). Proceed north. Kill kobolds and oozes, mind the traps. Reach shrine, then drop down and run south.


 * When a rune is lit a "sigil" is activated, and when Garko oozes over that, two things happen: 1) Garko, along with the cube Death Touch, is teleported ahead past the next barrier (so your current area is "safe", and only the next will be dangerous), and 2) the lever for the barrier to that next area is unlocked. There are 3 runes to light, 3 barriers to get through...

The way east is blocked by a barrier, so go west.
 * First rune: northwest room – Pipe jumping section, activate 3 runes until objective changes.
 * There is a lever (not shown on map) high in the center of the room, that starts an air jet from the pipes below. It's not necessary for completion, but it can help.
 * Second rune: Continue west and south from the pipe room. Go to the west first, just under the quest entrance (now less poisonous). Kill the horned devil. Loot chest, pull lever (rune), shrine if needed. Return to water, dive (east) to enter a pillar jumping section. Jump across and pull lever (rune).
 * Latecomers can jump down at this point and be safe from the earlier poison, but may still have some fighting to do, and possibly a red gelatinous cube to avoid, depending whether the main party has completed the second rune or not. Landing in the water and swimming to the western landing is a safe way to wait.
 * If you kite him out of the hallway (into the main room), the Horned Devil will white-dot and return to his starting point at full health.
 * This is the only barrier with a lever to lower it on both sides.
 * This is the only barrier with a lever to lower it on both sides.


 * Third rune: Go south across the drawbridge. Solve puzzle (in large eastern room).
 * While solving puzzle, you can squeeze back against the barrier and be safe from Death Touch. There is also a ladder south of the puzzle.
 * Note that unlike the previous 2 barriers, this one has no lever on the far side, creating a soft Point of No Return. The only way to get back (without releasing) is either Dimension Door, or to leave a character, hireling or pet on the far side to pull the lever from there. There are no shrines forward of this point.

Continue north (not over the drawbridge, although there is a collectable there), killing more ooze and kobolds. Then kill Garko along with some oozes and kobolds.
 * Garko starts alone, but he will summon help.
 * Garko cannot be kited out of the room, he will whitedot to his spawn location. Summoned trash can be kited and killed outside.
 * Killing Garko completes the quest; all trash disappears at that point.
 * The air jets on the raised platforms in the boss room cannot be disarmed.
