What is your favourite boss battle in Hades 2?

And why is it the sirens?

Seriously, I would love to know your favourite, but damn I fucking love the sirens. I never thought I would get to this point because for the first MANY times they completely overwhelmed me, and I almost gave up. But now, with that amazing music blasting, they've become easy to face and take down, but not enough to make them trivial and face them with no plan. And when you've a good build by the time you get to their room? Ohhhh it is so satisfying to take them down quickly.

Cerberus as well is a very very visually stunning fight that is stressful in a good way. Honestly the underworld route is a borderline masterpiece to me.

Any fights that particularly stand out to you?
