Hint: Defeating Galaban:
Start the battle with Galaban after the labyrinth. Do not heal if you have 60 or higher health. When he has the "laser" and goes downwards, get close and start slashing away. Note: Do not get too close. When the hands are destroyed (after about twenty hits for each hand), wait and avoid his attacks. When his gut opens, use the Power Ring and start slashing his gut once or twice. Note: Save the amulet for later. This will not do much damage. If you avoid the laser that is fired, heal as fast as possible (herb), then continue avoiding and slashing his gut when its open. Note: Use the amulet in your first battle on his gut when it opens, then intentionally die to see how much damage it does for the finish. When he has low enough health, kill him with the amulet.
