Let me explain how Honkai Star Rail handles gearing. Every single character has six relic slots: head, hands, body, feet, planar orb, and planar ornament. These relics go from level 0 to level 15, and four of them have a randomized primary stat. They all feature four randomized secondary stats, and every three levels a random one of those secondary stats gets a bonus. Each relic also belongs to a set of relics, and characters benefit from having two or four pieces of a given relic set. That means for every character in your party, you need to get the right items at the maximum rarity, the right primary stats, the right secondary stats, and the right level-ups for those secondary stats.

This is min-maxer mindset and I would hope randomized systems like this will prevent it but unfortunately no: even here some people think they actually need to roll every dice exactly the right way. I don’t think it’s true that this is really necessary. And no, it is not necessary to do top 10 world parses; you can just beat endgame content on modest, casual difficulty and call it a day, rather than try hard to set a record.
