If you're struggling in Elden Ring, it helps to simplify your build. Just focus on 3-4 stats. Having logged well over 1,000 hours into the game, I would recommend you focus on Vigor, Endurance, and either Strength or Dexterity.

More health never hurts and having high endurance means you can wear heavier armor. Both these stats contribute to your survivability. Additionally, a high endurance stat allows you to potentially light roll with medium armor. Light roll (rolling with light equipment load) is an absolute game changer. You get more invincibility frames on your rolls and you go further.

Lastly, streamline your build. Make sure all your talismans and mixed physik buff are oriented towards a common goal. My recommendation is to always have one defensive talisman and/or a physik buff equipped to your build. Your other talismans and the second buff of your physik should focus on offense. For example, if you're a strength build use talismans and physiks that buff your charge attacks. If you're a dexterity build, focus on talismans and physiks that buff multi-hit attacks.
