A cold, icy peak reached only through the Slab, and home to the Faydown Cloak.
Mount Fay is one of Silksong's coldest, most remote areas, and one of its most rewarding to reach. Per the wiki, it is a mountain with near-vertical cliffs to the east and slopes to the west, an icy region accessible only via the Slab.
It is gated behind a movement ability. The wiki specifies you need the Clawline to access it, reaching it from the west side of the Slab's Bellway.
The payoff for the climb is real. Mount Fay holds the Faydown Cloak, a Mask Shard, the Silkshot tool, and the Act 3 boss 
Pinstress.
This guide covers how to reach Mount Fay, what lives there, the key rewards, and the hidden Brightvein sub-area.
A cold, icy mountain area in Pharloom.
Via the Slab, requires the Clawline ability.
The Faydown Cloak and a Mask Shard. Pinstress, an Act 3 fight here.Mount Fay is one of the harder areas to get to, sitting behind both a region and an ability gate. Per the wiki, it is west of the Slab, reached from the west side of the Slab's Bellway.
The key requirement is the Clawline. The wiki states the Clawline is needed to access Mount Fay, so you cannot reach it until that mid-game movement skill is in hand.
Because it is cold and vertical, the area doubles as a platforming test. Reaching its rewards means climbing past icy cliffs and the creatures that nest on them.
Unlock the Slab's Bellway first so you can fast travel back. In actual play, Mount Fay is remote enough that a nearby Bellway saves a long return trip each visit.
Mount Fay mixes friendly faces with icy threats. Per the wiki, several key NPCs set up shop here alongside the area's enemies.
| Type | Who or what |
|---|---|
 Characters | Shakra, the Mask Maker, Fayforn, Mister Mushroom |
| Enemies | Driftlin, Mnemonid, Servitor Boran |
| Boss | Pinstress (Act 3 only) |
The returning 
Mister Mushroom and the 
Mask Maker make the cold peak feel lived-in, while Pinstress turns it into a combat destination once Act 3 begins.
Mount Fay is worth the climb for its loot. Per the wiki, the headline pickup is the Faydown Cloak, earned by playing the Needolin at the Tuning Fork.
| Reward | How to get it |
|---|---|
| Faydown Cloak | Play the Needolin by the Tuning Fork |
| Silkshot | Crafted using the Ruined Tool and Craftmetal |
| Mask Shard | Brightvein platforming challenge |
| Pin Badge | Reward for defeating Pinstress |
| Memory Crystal | Found in the area |
The Faydown Cloak is the standout, a major upgrade covered in our tools and abilities coverage. The Silkshot and Mask Shard make the detour pay off even further.
Tucked inside Mount Fay is Brightvein, a hidden bright cave with its own challenge. Per the wiki, it is a bright, icy cave reached by going south and west from the south-eastern bench.
Getting in needs a specific trick. The wiki notes you use Silk Soar on a rock floating in the ice water in the room west of the large chasm to reach it.
Inside is a platforming reward. The wiki specifies a challenge where Hornet bounces off Mnemonord enemies to claim a Mask Shard, a classic Hollow Knight-style movement puzzle hidden off the main path.
Mount Fay is wrapped in ominous lore about what waits at its peak. Per the wiki, a scroll at the base warns of a creature atop the mountain and a climb that is a test in itself.
The tablet reads that reaching the summit and hailing the creature means it "shall choose what gift to grant, with death as likely as insight." It frames the climb as a pilgrimage with real stakes.
That tone fits Pharloom's wider theme of dangerous devotion, the same pilgrim spirit that drives characters like the cartographer Shakra across the kingdom. Mount Fay is a holy, hostile place.
Mount Fay is one peak in a huge kingdom. These guides cover the cast, bosses, and builds you meet across Pharloom.
