Blaaz

Blaaz is a Wizrobe-like boss that appears in The Legend of Zelda: Phantom Hourglass. When the battle starts, he splits into 3 enemies, all of which are impervious to Link's sword. To attack him, you need to draw a path with your Boomerang that hits all of the enemies. Then, the boomerang will carry the enemies, until all three collide with each other. With a bit of luck, the "Mini Blaazes" will merge, and turn into the larger form. Then, you can attack but BE CAREFUL: as his name suggests, he can control fire, and even make large flaming rocks hurdle down at you. Repeat this process, and some Sands of Time, a Heart Container ,and the fairy of power, Reef will be yours.
