The Savage Beastfly is a boss in Hollow Knight: Silksong, where it is fought in the Chapel of the Beast in Hunter’s March. This battle is about that player’s skill on movement, timing and adaptation. Its defeat rewards Hornet with the Beast Crest, an important item that modifies Hornet’s fighting capabilities.
Savage Beastfly Boss Location and Pre-requisites
You can find the Savage Beastfly in the Chapel of the Beast, which is an isolated location inside Hunter’s March. In order to use the chapel, you will need the Drifter’s Cloak, to navigate the more difficult platforming parts of Hunter’s March. Instead, while players can encounter the boss upon entering Hunter’s March, this is not advised. Players should ideally explore further after they obtain the Grip Claw which will allow for better dodging, accessing Hornet’s arsenal more effectively, and with increased mobility.

Boss Mechanics and Attack Patterns
The Savage BeastFly utilizes both aerial and grounded attacks, and will utilize minions to distract and confuse the player. The Beastfly’s moves entail:
- Charge Attack: The Beastfly will charge towards Hornet but the angle of the attack will depend on Hornet’s location. If Hornet is down and near the outer edge of the arena, the Beastfly will collide with the wall, offering Hornet an opportunity to deal damage.
- Slam Attack: The Beastfly will hover for a brief moment, then slam down crashing at a very high speed. The slam attack can be chained and will crush summoned bugs. In addition, this attack can last for a long time causing Hornet to be able to tag the slam attack.
- Bug Summon: The Beastfly will roar and produce bug cases which will drop and give Hornet multiple bugs. These little minions can create a very confusing game but can be eliminated with either Thread Storm or baiting the Beastfly into performing a slam attack to smash them.

Combat Strategy
1. Utilize Ground Positioning
While staying on the ground is the most effective location for avoiding the Beastfly’s charge attack, if you stay near the arena’s edge, you will be able to damage the Beastfly the moment it collides with the wall and becomes exhausted for a moment.
2. Punish Post-Attacks
The Beastfly has a moment of vulnerability after it completes a charge attack and after it has slammed the ground. You can punish or damage the Beastfly in this moment of vulnerability with pogo jumps or a well-timed auto attack.
3. Eliminate the Bugs It Calls
The Beastfly may also summon minions, which can include bugs (which are communist little babies of the Beastfly), orbs which deal contact damage, and spikes. Legging them will become a priority of yours. You can Thread Storm to destroy them or bait the Beastfly to perform a slam attack that will destroy them.
4. Do Not Allow the Fight to Drag Out
The Beastfly will probably continue to summon more minions as time passes, so you’re gonna have a hard time staying on top of it to not get overwhelmed and lose. Try and smash the Beastfly as hard as you can, because you want to limit the minions it spits out and want this fight to be as short as possible.
Rewards and Aftermath
When Hornet destroys the Savage Beastfly, she attains the Beast Crest and it changes how she fights entirely, increasing her savage slashes and also giving her the ability to lifesteal. On top of that, the Beast Crest also gives her 2 slots for red charms and 2 slots for yellow charms allowing for loadouts that increase both offense and utility.

Use the Invulnerability Frames: When you’re fighting bugs you’ve summoned, take their invulnerability frames to heal or to get a better position.
Disarm the Traps Before Resting: There is a bench right next to the Savage Beastfly arena but it’s trapped. Before you rest at the bench, destroy the hidden wall that activates the trap. This way you’ll have a safe respawn point when you die.
Unlock the Shortcuts: After you finish the platforming puzzle in the Chapel of the Beast, hit the lever to unlock the shortcut that allows you to get to the boss arena faster next time.
