I like the Blue Ring and Red Ring as items, as the multiple color schemes make Link more visually interesting, but attaching them to any other items would just feel tacked-on. However, some people don't like what the Rings do in SMBC: it's been pointed out that Bombs didn't damage Link in the original LoZ, so the Blue Ring is unfaithful, and some people think that Link should start with the Sword Beams, or they should be attached to the Magic Sword, or Mushroom, or something else. Since the original function of the Rings (reducing damage) is not relevant to SMBC, I offer new functions based on similar items from later games: Blue Ring: Allows Link to swim in water, Link's Awakening-style Justification: The Zora Armor from Twilight Princess allowed underwater swimming, and it was also a blue outfit. Red Ring: Makes Link immune to firebars in castles (like Samus' Varia Suit) Justification: The Goron Tunic from Ocarina of Time allowed Link to stay in hot areas without getting hurt and prevented fire-based attacks and obstacles from setting him on fire, and it was also a red outfit. I'm not one hundred percent happy with these ideas (I'd be fine with swimming being an inherent ability for Link, and the firebar thing is a bit of a stretch), not am I particularly unsatisfied with the Rings' current functions (although I would like the Magic Sword and Red Ring to be separate again). However, as I said above, I know other people are unhappy, so I'd like to know what you think of these ideas.
