Beginning the quest
When you start the mission, you can notice a Shrine in front of you. Visit it and then go down the path. Watch out for two enemies lying on the ground. When you get closer to them they will stand up and start attacking you. The best way is to approach them one by one. You can find a chest inside of the building that is behind them. When you go further you must turn right. There, you can see spider eggs and behind them you can find corpses that can be looted. Change your combat stance to high because small spiders will come out of the eggs. They are hard to hit and that's why you should use that stance.
After searching the corpses, you can then go up by using the spider web. When you reach the top, you must watch out for a spider that will attack you. You must especially watch out for its web with venom that it spits out because it inflicts a status that slows you down. The best way to deal with them is to use blocks and dodges. When you reach the top, you must go on a rooftop from which you can take out an archer that stands on one of the towers.
While you are on the rooftop, you can shoot the cocoon presented in the picture. You lure a giant spider and open a passage to another part of the location. At first, fighting with this enemy may seem difficult because it's bigger than the other spiders and its attacks are much stronger. However, blocks and dodges are your key to success. When you defeat the enemy, it will drop 1 Hiragumo Teakettle fragment. On the right side of the door you can find another spider located on the wall. It will attack you when you get closer to it. After eliminating the enemy, you can pick up items in this part of the location. Use the ladder and reach the tower on the left. There, you can find a corpse that can be searched. Another body is in the building next to the tower, the one on which the archer stood. Watch out for spiders inside of it. Another corpse can be found on a rooftop of the burned building. If you want to get there, you must go around it and reach its back. After that you must climb up by using a spider web. There, you can find one bigger spider and a few eggs.
Area near the bridge
When you are done with this part of the location, you can use the door on which the cocoon was before. Cross the bridge and activate a Shrine. Next to it you can find door, however, you can't open them from this side. They can be opened later. Move forward and stay close the wall. At the end of it, between stones, you can find spider eggs and a corpse that you can loot. Move forward and defeat a spider that stands on the path.
When you move further, you must watch out for a boulder that will roll towards you. When you hear a characteristic sound, you will have to hide near a wall. You can notice an archer that can be eliminated from a distance so he won't interrupt your upcoming fight with a Yoki. After that you must follow the path. You can notice a corpse behind a corner. Go to another square and watch out for an archer located on the tower on the right. You can also find useful items located on the same tower. The square contains two more enemies: a skeleton and a Yoki that are inside of the building. When you attack the Yoki, you may be attacked by small spiders that can come from the eggs. You can skip this fight but you will lose a chance to get some items.
Jump down into the building by going through a hole in the roof and defeat a spider that is inside of it. When you leave this place, you must head right immediately because there, you can unlock a shortcut from the last Shrine that you activated. When you open the door, you can get into the water and collect items. After that you must defeat another spider that blocks the passage with a cocoon. By defeating it you get the second Hiragumo Teakettle fragment. Open the door that were blocked by the spider and move forward.
Leave the building and head left. Watch out for a spider that will attack you from behind. Then, you must head to Yokai Realm and defeat a Yoki and a spider. Collect items from the corpses, open a chest and head towards a passage between a wall and a building. Reach the end of it and enter the building inside of which you can find a chest. Then, use the ramp and enter inside. A Yoki and a corpse that you can search can be found behind the wall on the left. A few steps ahead there is a spider and another corpse.
Left from the ramp you can find a room with spiders and a Yoki. When you defeat the enemies, you will be able to pick up Key to castle gates from corpse. You can destroy the screen on the left of the corpse, this unlocks a passage to Hot Springs. After that you must leave the room and head left. Watch out for the archer located near the exit from the building and for an enemy with a spear that will attack you from the right. Defeat them, collect items and open the gate. When you enter the garden, you must immediately open another gate, this will unlock a shortcut. Then, head towards the corner of the garden.
The undergrounds and the castle
Jump down the hole presented in the picture above and don't worry, the spider web will break the fall. During your exploration of the caves you must watch out for spiders that hang down from walls and ceiling. If you want to kill them, you can either use a ranged weapon or get closer to them so they can jump on you. If you chose the second option then you must watch out for damage that they can deal you. After defeating all spiders in the first part of the cave you can move forward by going through a corridor. Before you approach the cocoon, you must provoke a Yoki to attack you by, e.g. using a ranged weapon. After killing another giant spider, you will get the third Hiragumo Teakettle fragment. Search other parts of the cave and move forward by going through the corridor. Use the ladder and go up.
When you reach the surface, you should go down the path on the right. Defeat two enemies and collect items. Then, you must go back towards the ladder. Next to it you can notice a place with spider web. Climb up, reach a rooftop and drop the ladder down. This unlocks a shortcut. Then, you must head left from the ladder. Move forward and watch out for a Revenant that will attack you, even though you didn't summon it. After that you have to face new enemies, including another Revenant. Defeat the giant spider from a cocoon and you will get the fifth Hiragumo Teakettle fragment. Search this place carefully and then head towards the ladder on a rooftop, the one that you dropped. Go back to the Shrine near the bridge and head towards the enemy that threw the boulder towards you.
Defeat all enemies that reappeared. You reach the place where you jumped down. This time, you must go up and follow a path that can take you near a building with a Yoki inside of it. On the top, you can find a gate that can be opened with the Key to castle gates. Behind them, you can find another Shrine. Next to it there is a building, however, its entrance is blocked by crates. Destroy them, enter inside and search a chest. Follow the path that goes between rocks. A skeleton awaits you behind the corner. Defeat it and go down a ladder. Watch out for an enemy with a spear that will attack you from the right. A few steps later you will come across two spiders. One of them is inside of a hole in a rock and the second one is near the bridge made out of spider webs. Defeat the enemies and open a gate. This unlocks another shortcut. You must also kill a giant spider from a cocoon and pick up the fourth Hiragumo Teakettle fragment. After that you must go back to the Shrine.
When you go back to the Shrine you should first go near the stairs and search a corpse. After that you can go up. When you reach the top, you will be attacked by a Wheelmonk. Watch out for an archer that stands on stairs. You can defeat it by using a ranged weapon. Another cocoon can be found on the left side of the building. Defeat the spiders and collect the sixth Hiragumo Teakettle fragment. Enter the building and watch out for another spider that will jump on you from the ceiling. Move forward. When you get closer to the stairs, you will be attacked by a skeleton and yet another spider. When you go up, you must watch out for a Sentry that guards the stairs. The best way to deal with him is to make him go down. There is another spider that waits for you. When you defeat the enemy, you should wait with going up the stairs. Instead, you should jump down on a spider web. Thanks to that you are now in a room with a Shrine and a gate that you can unlock. You may also go up and collect treasures. Watch out when you are opening the big chest because you will be attacked by a Mujina. After that, you must go back to the stairs. There is a door on top of them that leads to the arena where you have to face the boss - Joro-Gumo.
