How To Beat Fourth Chorus in Silksong

Fourth Chorus is a sneaky boss that doesn’t appear when you reach its location. Instead, it only appears after progressing further in Far Fields in Silksong. It surprises Hornet and starts attacking immediately, taking down the ground beneath her.

Fourth Chorus Location in Silksong

To trigger the Fourth Chorus boss fight in Silksong, go south of the Far Fields region, where Hornet will get stuck without having the Drifter's Cloak. You need to progress further into that area and complete the Flexile Spines quest in Silksong. This will give Hornet the ability to float, and she’ll be able to leave that area. On the way back, Fourth Chorus will wake up, and you have to go through the Fourth Chorus boss fight to get out.

Fourth Chorus Weakness in Silksong

Beating the Fourth Chorus boss is simple, as you only need to target its heads with attacks. Of course, the boss mechanics make it a little more complicated as it keeps attacking and removing the ground underneath Hornet.

Use the upward hit by pressing attack + up button, then jump to hit the boss.

The two main attacks Fourth Chorus uses are a sweep that you can avoid by jumping. As for the second main attack, Fourth Chorus hits the ground and removes it for a period of time after contact. The boss will keep spamming this ability until Hornet is barely standing on anything, which makes aiming for the Fourth Chorus’ head harder.

No matter what happens, the main priority is to keep jumping and hitting the head, which is enough to defeat Fourth Chorus in Silksong. However, for players struggling to aim for the head, there’s an alternative method to beat Fourth Chorus in Silksong. In the last phase, after taking Fourth Chorus down twice, two wind currents will appear on each side of the boss fight.

Use them to float above Fourth Chorus and attack the two explosive lava rocks from each side. That will trigger the middle rock to fall on Fourth Chorus’ head and defeat it immediately. In the end, whether by only attacking the head or additionally letting lava rocks fall, both methods work to beat the Fourth Chorus boss fight in Silksong.
