Flukenest is a Charm in Hollow Knight. It replaces the Vengeful Spirit/Shade Soul Spell with a horde of damaging flukes.
Usefulness
Using Flukenest is primarily a preference-based decision, as range and consistency have to be sacrificed for approximately double damage. Flukenest's main advantage is the massively increased damage compared to not having it, which can be helpful for bosses.
Wearing it unlocks extra dialogue with 
Fluke Hermit.
How to Acquire

Replaces the horde of flukes with one massive, volatile fluke that does 3 impact damage and explodes into a dung cloud that lasts 2.2 seconds and deals 20-23 damage. |
Charm Combo Tips
 Shaman Stone |
Shaman Stone increases the damage to 5, resulting in a total damage of 45 with Vengeful Spirit and 80 with Shade Soul. Fluke projectiles are also, on average, 31.9% bigger.[Note 1] Shaman Stone only affects the Defender's Crest + Flukenest combo by increasing the damage frequency, allowing for 26-30 damage. |
Trivia
- This charm does not damage the Hollow Knight or the
Pure Vessel (except when they are in the air). - Prior to the Lifeblood update, Flukenest cost only two Notches and dealt 5 damage per fluke (7 with Shaman Stone).
- Save files created before the update are not affected by the cost change.
- The flukes change appearance depending on the Spell and whether Defender's Crest is equipped.

Notes
- ↑ Without any Charms, the size multiplier for the fluke projectiles is a random number between 0.7 and 0.9. With Shaman Stone, the multiplier is a random number between 0.9 and 1.2.
