I'm pretty bad at Hades. Everywhere I see people defeating it for the first time on attempt 17 or 18. Here I am at attempt 35 and I still haven't beaten the last boss yet.
I've beaten the third boss about three times now. On my last run, I was doing really well. I had the Athena deflect dash and was slowly killing the last boss. Then I screwed up and lost a lot of my health quickly. With a sliver of health left, I managed to deal the final points of damage, reducing the boss' health bar to zero. I was so excited!
Then Phase 2 started.
It was chaos, with spinning beams of fire everywhere. I panicked and died a couple seconds into the new phase.
Oh well, on to the next attempt.
