Found at 1435W, 616S, this is the location of the Throwing Mastery Quest and it will show on the world map once you've accepted it from Clarissa Shalmo. It is a series of mini mazes which require hitting specific targets with ranged weapons to advance to the next level. There are 6 levels in all, not counting the entrance level
The passage leading to K'na Tha is located just east of where you start out.
Point 1 is your start point and exit, Point 2 is a chest with some goodies and ranged weapons in case you don't have any or if you only have the Aerial Decapitator (which does not have sufficient range for this quest). Point 3 is the Middle Torch which must be hit to advance.
This is a mini dungeon without too many branches that you can explore. There is some loot and some monsters that you can kill. There are several locked doors that can be unlocked or destroyed. Eventually find your way to a new set of torches. Point 4 is your reference point. Point 5 is the far Right torch that you must hit. If you shoot the Left torch then you'll be teleported to level 1. If you shoot the Middle torch then you'll be sent back to the beginning of level 2.
This is a simple puzzle to solve. Ignore the doors and disregard the darkened area. Just hit the unlit torch on the Right of the room. When you do so then you'll be teleported to the next set of torches. Point 6 is your reference point. Point 7 is the is the far Left torch which you must hit. If you hit the wrong torch then you'll go back to the beginning of the level.
Again this is a mini dungeon without too many branches that you can explore. And again just ignore the darkened areas. There are some monsters that you can kill, but you cannot reach them to loot them. Eventually find your way to a new set of torches. Point 8 is your reference point. Point 9 is the Middle torch that you must hit. If you hit the Left torch then you'll end up back at the beginning of level 3. If you shoot the Right torch then you'll end up at the beginning of level 4.
Again this is a simple puzzle room. The gimmick here is that you must kill all of the enemies that spawn each time that you kill the current enemy. This goes on for six rounds. Once the enemies stop respawning and are all killed, then you can advance. Point 10 is your reference point. Point 11 is the lit torch that you must hit.
This is the final level. Point 12 is the alter where you'll find Azram's Star. Point 13 is the unlit torch which you must hit to return to level 1 and point 1 (your exit).
