The Snail Shaman tomb on the west side of Fog Canyon, near the Queen’s Gardens entrance. Houses the Howling Wraiths spell pickup behind a Squit gauntlet arena.
The Overgrown Mound is a small Snail Shaman tomb sub-area on the west side of Fog Canyon. Per the wiki, it sits "near the Queen’s Gardens" connection and "now overgrown with flora." The mound is one of the smallest named sub-areas in the game.
The buried lede is the body in the back. According to the wiki, "at the end of the area is the body of the larger cousin of the Snail Shaman in Ancestral Mound, who was not known to be generous but did have a good voice." The Howling Wraiths spell sits next to her corpse, drawing on her voice as the in-fiction sound source.
The wiki specifies the spell pickup is gated by a four-wave Squit arena. Mantis Claw is required to clear the gauntlet, so the mound is effectively post-Fungal Wastes content even though it sits in Fog Canyon.
This guide covers the west Fog Canyon entry near the Queen’s Gardens stairway, the Mantis-Claw gated Squit arena and its four-wave layout, the Howling Wraiths spell pickup and Abyss Shriek upgrade path, the larger-cousin Snail Shaman body lore, the Geo Deposit pickup, and the narrow ledge to Queen’s Gardens just east of the mound.

Mantis Claw for the gauntlet wall-jumps.
Pre-Mothwing Cloak; cannot reach Fog Canyon yet.Per the wiki, the Overgrown Mound is "a Snail Shaman mound near the Queen’s Gardens, now overgrown with flora." The mound shares its core structure with the Ancestral Mound in the Forgotten Crossroads, where the first Snail Shaman still lives.
According to the wiki, the architecture is recognisable: circular stone walls, a sloped entrance, a central chamber, and a deeper corpse-and-spell pedestal at the back. The visual mirror to Ancestral Mound is one of the cleanest environmental cues that the same Snail Shaman culture built both sites.
The wiki specifies the only enemy in the mound is the Squit. Squits are small flying biting insects from Fog Canyon and Greenpath; they spawn four-at-a-time in the gauntlet arena rather than patrolling the corridors normally.
Per the wiki, the mound sits in the west part of Fog Canyon, near the connection to Queen’s Gardens. Reaching it requires navigating Fog Canyon’s main corridors first, then dropping westward past the Howling Wraiths signpost.
According to the wiki, the canyon itself requires Mothwing Cloak minimum (for the Greenpath route in) and Mantis Claw for the mound gauntlet itself. The route from Greenpath north into the canyon is the only pre-Shade-Cloak option; the central and east routes all need late-game mobility items.
The wiki notes one Geo Deposit sits in the mound itself, separate from the spell pickup. The deposit is on the corpse-pedestal floor; the four-wave arena does not unlock the deposit, just the spell.
Bench at the Fog Canyon entry chamber before attempting the mound. According to the wiki, there is no bench inside the Overgrown Mound itself; in practice, players who die in the Squit gauntlet respawn at the previous bench, which adds 1-2 minutes of re-traversal per attempt.
Per the wiki, the spell pickup gate is a four-wave Squit arena in the centre of the mound. Mantis Claw is required because the arena walls are sheer; without wall-jumps the Squit waves corner the Knight on the ground.
| Wave | Squits | Position |
|---|---|---|
| 1 | 2 | Centre + top centre |
| 2 | 2 | Top centre + middle right |
| 3 | 2 | Top left + middle left |
| 4 | 3 | Top right + middle left + middle right |
According to the wiki, the Squits attack on contact rather than projectile-throwing. They dive at the Knight, bite, and retreat; punishing the dive with a nail swing or Vengeful Spirit one-shots most of them per hit.
The wiki specifies the arena theme switches to "Crossroads (Action)" during the fight, the same combat track used for the Forgotten Crossroads enemy rooms. The audio cue is another environmental tell that the mound and the Ancestral Mound share a cultural lineage.
Per the wiki, completing the Squit gauntlet unlocks Howling Wraiths on a pedestal next to the Snail Shaman corpse. The spell fires an upward cone of wraith screams that damage every enemy in the cone.
According to the wiki, Howling Wraiths upgrades into Abyss Shriek at the bottom of the Abyss. Abyss Shriek roughly doubles the cone damage and adds a Void shockwave effect; it is the highest single-cast spell damage in the base game.
The wiki notes the standard spell-build pair: Shaman Stone for +33% spell damage and Spell Twister for -9 Soul per cast. The pair turns Howling Wraiths into a crowd-clear rotation that one-shots most mid-game enemies.
Per the wiki, the body at the back of the mound is "the larger cousin of the Snail Shaman in Ancestral Mound." She is the second of two named Snail Shamans in Hallownest; the first still lives in the Crossroads and sells the Vengeful Spirit spell.
According to the wiki, the body description carries character: she "was not known to be generous but did have a good voice." The in-fiction reading is that Howling Wraiths channels her voice as the sound source for the spell, which is why the pedestal sits directly next to her corpse.
The wiki specifies no Dream Nail dialogue exists on the corpse. The contrast with the Ancestral Mound shaman (who is alive and sells two of the three spells) is the strongest character beat: one shaman survived to serve, one shaman left her voice behind in a tomb.
Per the wiki, the Overgrown Mound sits "near the connection to the Queen’s Gardens." A narrow westward corridor from the mound leads to a thorn tunnel and a stairway up into the Queen’s Gardens east entry.
According to the wiki, the route is one of three paths into the Gardens. The other two are the Fog Canyon bottom Isma’s Tear acid pool and the Deepnest Mask Maker hidden wall with Monarch Wings; the Overgrown Mound route is the cleanest pre-Shade-Cloak option.
The wiki notes the corridor between the mound and the Gardens doubles back on itself with multiple thorn pits. In practice, most players route the mound -> Gardens path westward on the first Fog Canyon visit, then come back east with the Howling Wraiths pickup in hand for the rest of the run.
The Overgrown Mound holds a single spell and a single piece of Snail Shaman lore. These spokes pick up the threads around the spell and the canonical build pair.
