In Elden Ring, Mana or FP becomes an important resource for any build centered around sorceries, incantations, and weapon skills. By leveling up the Mind stat, you can increase your focus points as well as focus, which lowers the buildup of sleep and madness. However, increasing your Mind stat doesnt help the damage of your attacks and is mostly a quality-of-life stat if you mind drinking the Flask of Cerulean Tears frequently.
