Hate to do some backseat gaming but I would recommend changing the Havel armor for something different. With your current hp it doesn't make that much of a difference and going down to atleast medium equip load would be a huge help since fat rolls are the worst. Also level Vitality to 30. Sorry
So she should just stop making choices on what load out to use and stop experimenting and enjoying the game her way and use your set up because it’s superior to all of them? Should she just play following a walkthrough doing everything a specific way? She should go everywhere in order and never step out of line? How is that any fun? Games are about enjoying it your way otherwise what’s the point of all the items in the game? Why can’t she use what she has? Did she ask for help or tips? No she’s sharing a victory, a positive, and you brought her down. She looks like a high level what does it matter what her stats are and why should she have to listen to you at all? You don’t want to backseat game then simply don’t there is nothing more too it. Maybe you should be impressed someone else thought of their own setup that works and didn’t just copy what Google said or do whatever the “meta” is. She killed the boss and I’m going to guess isn’t concerned with numbers or the nitty gritty details pulling up excel pages with stats and numbers. Give her a tip on the game or encouragement but for the love of god don’t tell her she’s playing it wrong and to change everything about the way she’s going at it. All that pompous, boastful and holier than thou nonsense just makes everyone else see that your soul, the soul of a toxic undead man who mansplained to people online until they went hollow from insanity.
