Hello! I was doing an underworld run and something weird happened, which lead to a VERY fast Underworld boss fight. I've screenshotted my boons and stuff at the bottom for additional context.

Now, during the fight, I didn't kill all the ads that Chronos spawns. This wasn't intentional, it was just a thing that was happening. He was afflicted by both Steam (from the Pos/Hes duo boon), Slip, and Scorch. It was pretty normal through phase one.

When I hit Chronos down to the end of his first health bar, though, it suddenly showed as half full. As in, it went from empty to only half empty, even though he was kneeling. Then it went empty, and refilled for the second health bar. During that second part of the fight, there was no invincibility phase between when he summons the hourglass ads and when he's solo. In fact, he sort of didn't do anything? Just floated while frozen to the center of the arena and then finally preparing to fire off his insta-kill attack... which he also got damaged out of?

Sorry I don't have a video, I don't usually record my runs. If anyone has any idea of why this happened, I'd love to know!
