Like a lot of players right now, I've been farming brandstone meteorite sites for rose quartz dust (and more kralk) in order to make Astral weapons. I think there might be some misunderstandings about how the surface brandstone site specifically works, and please let me know if anyone's figured this out. I do agree that spamming the Multitool's #3 skill "Extraction Beam" as much as possible is a good idea for getting lots of loot. And people say that not damaging the meteorite (and thus letting the event fail) is how you maximize mining returns. However, I don't think that's the right strategy. According to the wiki, more of the meteorite's shell breaks off as its HP hits 75%, 50%, and 25%. My theory is that you spam #3 at the beginning (max out the site markings) and then you'll hit a cap. Once the HP hits 75%, I think the cap resets and you spam #3 again. Rinse, repeat until 0%, preferably when the timer is nearly up. I think the right strategy is to DPS the meteorite slowly. That way, you cap the number of times Extraction Beam gets loot, but you keep breaking off more shell in order to reset the cap. I've had the event fail when the meteorite's HP is still at 80%, and have gotten hardly any loot (30ish kralk) even though I was the first on site and was spamming Extraction Beam the whole time. Others have said they get over 100 kralk, and I'm betting that was when the meteorite was getting slowly DPS'd by people they were screaming at to stop hitting it.
