Phase 1

The drill attack is the most iconic moveset of the Raging Conchfly, and Hornet must avoid it at all costs. The boss darts towards you and burrows within the wall and roof upon impact. Yes, the drill attack indicated by the smoke can be either horizontal or vertical.
Additionally, you have to watch out for the conch spit attacks, which ricochet off of walls.

Dodging is crucial for survival. Be careful of the random delayed drill attack, which has a short windup time. The boss also uses all of his Phase 1 movesets.
Tips and tricks to defeat Raging Conchfly in Hollow Knight Silksong

Here are some general tips to aid you in the battle:
- You must dodge the drill attack and conch spit, as they can take away a chunk of your HP. Watch out for the smoke, as it indicates that Raging Conchfly is about to dart out of hiding.
- Try to pogo on the boss to gain extra momentum.
- You can strike the minions in the second phase to get rid of them. We recommend dodging their attacks instead, as they despawn after a short time.
