After warping to the Smithing Grounds, area 2-1, head slight left and defeat the crystal lizard for a Shard of Sharpstone and pick up the soul on the nearby corpse. Head back to the merchant just outside Stonefang Tunnel and purchase/sell as needed. Head right from the merchant along the wall toward the rocking throwing Miner enemies. Time your entrance, taking care not to get hit by the rocks, and enter the doorway. In the right is a wheel contraption. Use it to activate and take the outside lift up a floor. In the upstairs room is a corpse with a soul on it and a Fat Official enemy. Dispatch him while trying not to aggro the Miner enemies outside. On the outside ledge, pick up the Crushing Battle Axe. Now that you’ve cleared upstairs, head back outside to the lift. Use the lift to head back down a floor.

(Optional: before heading down a floor, you can use the right side of the lift to head all the way down to the cliff side and pick up a Stone of Ephemeral Eyes).

Once back on the main floor, head straight through the storage room. There are a few Miner enemies that you will need to deal with before advancing. They are slow but attack in large groups, so be cautious. Exit the storage room and you will advance into a large courtyard area. You will encounter several more Miners. Straight ahead and slight right there is a doorway covered with debris. There are enemies behind it that will break through, including several Dog enemies. Dispatch them before advancing through the door. Inside is another Fat Official blocking the next doorway. Clear him and loot the corpses, yielding a Chunk of Hardstone, Chunk of Sharpstone, and Shard of Clearstone. Head back to the previous room and then turn left down a new doorway. A Miner is hiding on the right side of the entrance. Depending on your weapon type, it may be difficult to connect with him due to the tight quarters. Lure him out to make it easier. Once done, head through the doorway to the left, passing several wall torches. As you head up the stairs, you will be greeted by more Miners. Mind your surroundings, luring them back out to the previous room if needed. Once you have cleared the miners, head through the right doorway to grab the Pickaxe weapon. Head out of there and keep moving up the stairway.

After climbing the stairs, you will be overlooking the courtyard area. Keeping heading up to pick up a soul on a corpse. From there, attempt to cross the bridge to the other side of the courtyard. You will fall through debris to the next level down. Several Miners are on this level. Circle around clockwise to reach the other side of the courtyard. In the far left corner there is a lever. Activate it to raise a gate you need to advance. Head back to the other side of the courtyard, back to the bridge that you fell through. Head up the stairs to make your way to the gate you opened and a new fog door.

(Recommended: Ignore the Fat Official on the platform below unless you really want the corpse soul. You will need ranged attacks to effectively defeat him and make it over to the platform.)

1st Fog Door

Enter the room and head right to pick up a Shard of Meltstone. A fire lizard will fall down here, so be careful. Now, head up the ramp to the second level. Turn left of the wheel to head up to the third level. Grab the grass in front of you and cross the short bridge. Turn left and then right into a room with several fire lizards. You can fight the lizards and obtain a Shard of Dragonstone or skip this room. Past the fire lizard room, keep heading straight where you will encounter more Miners. Skip the fog door on the left for now and head out to the outdoor balcony ahead. You will find Moon Grass and a soul on the balcony area. Head to the right side of the balcony area, down the ramp and you will find a wheel contraption. Use this to activate a lift that acts as a shortcut to the starting area. Take the lift all the way down. Head through the small room where you can find Blacksmith Ed. Upgrade your weapon(s) and repair equipment if needed. Out on the balcony area, you can grab another soul.  Heading back up the lift, you can grab a Shard of Clearstone on a middle platform. Head all the way back up the lift and make your way back to the fog door you previously skipped.

2nd Fog Door

Head through the fog door and up the stairs. More Miners await. In the smithy room, pick up the Large Hardstone Shard. Heading through the forward doorway, follow the walkway left to find a crystal lizard. Be careful as the area is heavily guarded by rock throwing Miners. Ranged attacks are particularly effective against these Miners. Advance down the walkway and grab the Steel Shield. Head across the bridge and up the stairs. Keep heading up towards the fire lizards. They will drop down when you walk by them. Ranged weapons (excluding fire spells) are a safe way to get past them. Pick up the Shard of Dragonstone and then head left down the stairs. Watch out for the Dogs in this area. Grab the Ed’s Grindstone and then head across to the wooden walkway. Pick up the Moon Grass while you make your way to the bottom surrounded by Miners. Lure them out or use ranged attacks  to avoid getting mobbed. Pick up the soul under the stairs and make sure to loot the miner with the sack (it is full of upgrade materials). Head forward and use the wheel contraption, which will redirect the water flow on the big wheel.

Post Water Redirection

Head forward, dropping down to the level below. Then head right and up the stairs. Follow the walkway around to the location you have previous been to (just past the fire lizard room on the right). Head down the stairs on the right, looting the Large Sharpstone Shard and Moon Grass. To the left of the waterfall is the Ring of Poison Resistance. Head all the way up the stairs on the left. Moving forward, you will head down some stairs that lead to a room full of fire barrels and a Fat Official. Head down the pathway up into a webbed cave area. Follow the walkway until you reach an elevated wooden platform and debris. Head straight under the platform turning left and moving up the platform where you will find the Kris Blade. Head back down and activate the wheel contraption on the right. Before heading through the fog door, grab the Chunk of Spiderstone down the corridor on the left.

Now, prepare for the boss battle with Armor Spider!
