For those playing the standard version (which includes DLCs like Ashes of Ariandel and The Ringed City in many repackaged versions), the "depth" comes from its RPG systems:

: Each weapon has a unique special move that consumes FP, allowing for varied tactical approaches beyond standard light/heavy attacks.

: Features like FP (mana) regeneration over time via specific rings and increased lock-on distances.

: A seamless dark fantasy landscape where verticality and hidden shortcuts reward thorough exploration. DARK SOULS™ III - Complete Guide - Steam Community

: Adds a "poise" system similar to the original Dark Souls and introduces "perfect block" mechanics (Sekiro Parry).
