In this extensive guide, we’ll explore how you can beat one of the optional bosses, called Savage Beastfly in Hollow Knight Silksong.

Savage Beastfly in Hollow Knight Silksong is one of the toughest early optional bosses that you can face. Due to the encounter happening in the initial stages of the game, new players might struggle quite a bit against this elite enemy. However, once you master its moveset and time your dodges and attacks perfectly, getting through this battle is far easier.
In the following guide, we’ll give you a complete overview of this battle, including where to find the boss and some strategies to use against it.
Where To Find Savage Beastfly in Hollow Knight Silksong

You will have to unlock access to Hunter’s March if you want to take on this optional boss. For that, the first step is to defeat Skarrguard in The Marrow. After doing that, you should head to The Chapel of the Beast location in Hunter’s March, which lies to the far right of this region. Keep in mind that you’ll have to fight off several Skarr Ant enemies before you can reach the location of the optional boss. Another thing to note here is that you will need the Swift Step ability and the Drifter’s Cloak to reach the boss’s location. Both of these unlock in the Far Fields region.
Also, you don’t need to complete the Savage Beastfly battle the first time you come across it. You can simply mark the location and return at a later time, when you have further developed your skills and abilities. However, we strongly suggest not skipping the fight entirely, since the reward from the boss makes this encounter completely worthwhile.

Savage Beastfly Boss Fight Overview

The boss fight has two phases that you’ll have to master.
First Phase
The first phase of this boss fight is relatively simpler than what the next phase holds. During this stage of the battle, the boss will simply dart from left to right, either at a height slightly above Hornet’s head or along ground level. You will need to judge the height beforehand so that you can take evasive maneuvers. Another attack you’ll have to watch out for is the downward headbutt.
In this attack, the Savage Beastfly will strike down at you three times in a row from above. Each of their attacks in the first phase will take off two masks. However, the boss also has a considerable hitbox that you should take advantage of.
Second Phase
The second phase begins when the Savage Beastfly calls in its allies to attack you. There’s some RNG involved in determining which type of additional enemies you’ll face here. Some of these enemies are more challenging than others. So, there’s some bit of luck involved too when it comes down to whether you’ll get enemies that are easier to take down.
The key during the second phase is to take down the minions before you focus your attention on the boss. In doing so, you can also utilize the Savage Beastfly’s downward headbutts. Time it correctly, and the headbutts will damage the minions caught in it. Besides the additional enemies, the moveset of the Savage Beastfly will remain the same. So, the following are the attacks you need to watch out for in both phases:
- Charge: The boss will dart toward you in a straight line three times. You need to judge the height at which these attacks are coming. Based on that, you can jump over it or simply avoid it and use a downward strike at the enemy.
- Downward headbutts: Three back-to-back downward thrusts from the air in a bid to crush you.
- Summoning minions: The boss roars to summon minions to aid in the fight. This only happens when the second phase starts.
How To Beat Savage Beastfly in Hollow Knight Silksong: Tips and Tricks

The following are some useful tips you can use to dominate this fight:
- During the initial phase, stay out of range for the Savage Beastfly’s attacks, and wait for opportunities to strike at them from below or the sides.
- Use the boss’s downward headbutt strikes to your advantage by letting them hit any of the summoned bugs.
- Reserve most of your Silk to heal during this battle.
- Use String Shard traps to deal additional damage to the boss. Simply make the enemy dash into one of these placed traps.
- Utilize the Warding Bell charm to protect Hornet from any attacks while she’s healing herself.
- Eliminate all summoned enemies first before focusing on the boss.
- During the battle, the Savage Beastfly may get staggered multiple times. Use these windows of opportunity to heal or to get in some additional damage.
After beating the boss, you will receive the Beast Crest from the room on the immediate left. This Crest enables Hornet to unleash a flurry of blows while also gaining lifesteal. The Beast Crest has two yellow and two red charm slots.
