This guide explains exactly where to locate The Slab map and how to reach it during your journey through Pharloom in Hollow Knight Silksong.
How to reach The Slab Area Map in Hollow Knight: Silksong
Before you can access the Slab, you’ll need the Key of Apostate. This key is located in the Bile Water area.
Once you have the key, make your way to the Coral Chambers. The slab region is on the left side of the Coral Chamber. Refer to the map.
From there, head left into the Slab region. Keep going left until you reach the teleporter section. Drop down and follow the path to reach the bottom.
At the bottom, continue to proceed to the right side, and you’ll encounter the locked door that requires the Key of Apostate. Use the key to open it. Follow below map.
Enter the door and head right, use the Double Jump ability to cross the gap, and then continue to follow the path until the end.
At the end, look up for a hidden pathway that requires breaking through an obstacle. Use Double Jump to progress upward.
Enter inside and move carefully through the tunnel while avoiding falling rocks. Continue upward and then left until you emerge at another exit of the tunnel.
Head left, and you’ll notice two additional locked doors. From here, continue climbing upward, then head right to reach a bench.
Go all the way to the right and jump across a pathway. At the far end, next to a body, you’ll finally discover the Slab Map.
