BS The Legend of Zelda/Quest 2/Dungeon 8

Before dungeon 8
From Dungeon 7's entrance go east, north, west four times, then bomb the left-hand rock outcropping to enter Dungeon 8.

Dungeon 8
Bomb the eastern face. In there you'll find eight blue Rupees as well as the Magic Book. This upgrades your Wand so that its blasts turn into flames when they hit something. Bomb the northern face, and repeat in the next room. Use bombs to defeat the Dodongo, then head north and collect the Compass (there are invisible barriers in this room, so move around until you can get to it). Then head south, west, west, north, north, and fight the fly boss again.

When it's dead push the block aside and enter the basement. Collect the Bombs and head north, then north, then west. Dodge the Wall Masters and head south. Here you fight three Dodongos. Afterwards grab the Bombs and head south to fight Aquamentus. This is the same upgraded version as seen in Dungeon 7. Head west to fight Manhandla. Head north to fight two Gohmas. Collect the Heart Container and  Triforce piece and you're done!
