@tearju-engi I haven't even tried to slay Behemoth, cause I feel like I'd be the one messing something up, especially after I saw in that first hunt where it flees, how ecliptic meteor messes with the camera. How am I supposed to find a comet to hide behind when the camera is forcing me to look at the sky?
Lunastra is basically just a ramped up Teostra though. I think you can interrupt the explosion with a flash pod, maybe, but yeah, if you get hit by it, you need to be immediately using an astera jerky because its recoverable damage.
I only did the Witcher quest once so far, and yeah, that was a really long fight. I think its only one quest, but like you said, there are side quests in the quest itself, which I didn't realize when I was doing it, aside from what looked like a few gajalakka tracks or something.
