SWORDS
KOKIRI SWORD- The treasure of the Kokiris. This is your first sword. Find it in the forest.
MASTER SWORD- This sword is da' dawg. It is what allows you to travel through time. You get it after collecting all three spiritual stones and playing the Ocarina of Time on the altar.
GIANT'S KNIFE- Not sure where you get this yet, but it breaks once you use it a few times.
BIGGORON'S SWORD- Similar to the Giant's Knife only it doesn't break.
SHIELDS
KOKIRI SHIELD- Buy it at the Kokiri shop or find it in the Dodongo's Cavern.
HERO'S SHIELD- Buy it at the Bazaar for eighty rupees. (if you talk to the guy at the gate before you buy it, the Bazaar man will give you a discount)
MIRROR SHIELD- Not sure where you get it or what it's used for.
TUNICS
KOKIRI TUNIC- You start with it.
GORON'S TUNIC- Go to Goron City as an adult and stop the rolling Goron with a bomb NOT a bomb flower and he will give you the Goron's Tunic. Use it to wear in the Fire Temple to protect you from intense heat.
ZORA'S TUNIC- As an adult, go to Zora's Domain and go back to Zora's Fountain where Jabu Jabu was. Hop across the ice-bergs to the heart piece and then back to the cave to find yourself in the Ice Cavern, a mini-dungeon. Beat it to get the Iron Boots. Now, before you leave, catch some blue fire in a bottle and take it back to King Zora to melt the ice off of him. Talk to him and he will give you the Zora Tunic.
BOOTS
KOKIRI BOOTS- You start with them.
IRON BOOTS- See above at Zora Tunic.
HOVER BOOTS- Not sure where to get them, but while wearing them, you can walk across water for short periods of time.
