Hollow Knight Silksong Collectibles — Mask Shards, Spool Fragments, Crests & Fleas
Pharloom hides four major collectible families, and each one upgrades Hornet in a different way: mask shards extend her health, spool fragments extend her silk, crests re-shape her tool loadout, and lost fleas pay out through the Flea Caravan.
Every family page lists its full set by act with one-click deep links into the Silksong interactive map — open a region filter or highlight the exact marker straight from the tables.

20 shardsAll 20 mask shard locations by act — every four shards extend Hornet’s health by one mask, with missable warnings for Bilewater and The Slab.
Silksong Spool Fragments

Silksong Crests
6 crestsAll six crests — Hunter, Vanguard, Wanderer, Reaper, Architect and Witch — with their passive bonuses and where each frame is found.
Silksong Lost Fleas
30 fleasAll 30 lost fleas by region, with the Flea Caravan rewards waiting once every cage is emptied.
