The Aegis's diagonal reflection seems a bit tricky to implement.
Allow me to propose some elaborations:
* Deku Shield (reflects rocks): Purchasable at Hyle Town for a bargain. Link does not start with this.
* Saucepan Lid (...also blocks spears, boomerangs): ???
* Iron Shield (...also blocks fireballs, flames, ice magic): A cold iron shield. Un-magical - but it can withstand basic elements. The only inedible shield. Idea: when you have it, you are magnetically "vaccuumed (as in Saffith's script)" toward Lodestone blocks?
* Polished Shield (...also reflects magic, sword beams, fireballs): A fairy somewhere can apply an unguent to your Iron Shield. If certain rooms contain a pool of light, then standing within it will cause a beam of reflected light to emanate from your shield.
* Aegis (...also reflects fireball 2's): Fireball 2's are the main weapon of several bosses...
And now:
Hover Boots.
* Hover Boots: Found in a secret cave in the Endless Desert.
* Levitation Boots (unlimited): Found in Chaos World, after the Zelda battle. Required to advance.
Boomerangs.
* Hoop spell (power 0, distance 40): Using a scant bit of magic, this spell sends a green energy ring to grab items and turn windmills. Purchased from a Wizzrobe in the deceased Kokiri Town.
* Boomerang (power 0, distance 40): A non-magical version of the above. Found in Ocean Labyrinth.
* Grasscutter (power 1, distance 50): Slight range difference, and does damage as well. Also slices Tall Grass combos (functionality to be implemented). What better place to find it than in a secret cave in Pol Prairie?
* Morning Sun (power 1, distance unlimited): Longer range, and sheds flames as it spins. Its solar aspect may allow it to rejuvenate certain wilted plants. Unfortunately, you can only rent it out for a limited time from the Rental Shop.
Magic Keys.
* Glass Key: A silver key with a white gem in the handle. Useless - but it can be enchanted with a spell from the Key Fairy who is well-hidden in each major dungeon (often requiring Ocarina music to summon).
* Emerald Key: Opens every locked door and chest in L1.
* Ruby Key: Opens the locked door and the locked chest in L2 (Fire mode).
* Sapphire Key: Opens every locked door and chest in L2 (Ice mode).
* Topaz Key: Opens every locked door and chest in the Temple of Light.
* Onyx Key: Opens every locked door and chest in the Temple of Chaos.
