Beating Dark Souls 2 without dying or using a bonfire rewards you with a ring that makes your right hand weapon completely invisible.

It isn't worth it at fucking all, since there is a spell that does the same thing and is way easier to obtain (even in 2025 despite being a multiplayer rank reward). The spell and ring also have ZERO effect on PvE and it rarely matters in PvP when the animations of your body instantly reflect the size of your weapon to a good enough player. Like, I don't need to see your Ultragreatsword to know that's what you are swinging when your arm starts hefting the weight.
