Brass Horn's Cave

I'm stuck on Brass Horn's Cave. In front of me, there's a note "Use what monster gives you" and a door, saying "You hear strange winds" while clicking on it.

The first time I came onto the cave, I've killed monsters but completely forgot what they dropped. I've tried to tap on the door with the Roar of Thor (main quest), and nothing happened.

Can anyone help me ?

Backup is to tap on the crack on the wall as you enter--you get a pole axe. Hit the gate with it to go further.

Found it ! Thank you !
