Argorok

Argarok is the boss of the City in the Sky, Twilight Princess's seventh dungeon. Argorok is an armored, fire-breathing dragon that is sighted throughout the level and destroys certain bridges.

Strategy
To defeat Argorok, use your Double Clawshot to climb up the pillars until you are close enough so that the clawshot will be able to register a latch point on the tail of the dragon. Once you have latched to it put on your Iron Boots and the dragon will fall to the ground, due to the overwhelming weight of the boots themselves. Once the dragon strikes the ground, due to its fall, it will continuously lose armor. After two more strikes, Argarok will violently shake, getting rid of any access armor he may still be wearing. Argarok will then begin to change tactics. Using the Double Clawshot, Link must make his way to the top of any pillar, then make use of the clawshot on a nearby peahat, a spinning animal who hovers in the sky. The key is to keep switching from peahat to peahat to avoid damage from Argarok's fire blasts, which will threaten to erase 8 hearts perchance Link is wearing the Zora Armor. After Argarok's fire rampage, he will stop to recharge, giving Link a chance to strafe to his backside. Using Link's clawshot as a latch, target the recharging beast, and Link will administer enough sword strikes sufficent enough to sent Argarok back into the air a second time. After repeating this technique twice, Argarok will finally admit defeat by falling to his death. A Mirror Shard and a heart container are Link's prizes for the destruction of Argarok.
