The Wing of Madoola/Stage 6

The waterfall traps
After both warp doors, you are presented with a dangerous trek across three waterfalls; one after the first warp door and two after the second. The bad news is if you fail to make it across those stones or bridges, you will drop to the bottom and be forced to enter a warp door that will return you to the beginning of the game. However, the good news is that the warp door drops you off right outside door A which contains a Spring of Strength. It's entirely conceivable that you may run low on health and intentionally drop down to the bottom of the waterfall just to benefit from the free health refill, even if it means retracing your steps. Additionally, the bottom of the waterfalls feature a slew of Nyurus which you can attack while squatting in an effort to collect potions which may increase your maximum health and magic. So don't despair if you fall down, it's actually a pretty good opportunity.

Recommended route
This stage is broken up into three distinct components, through which you will generally be proceeding to the right. In the first section, you will run from the starting point to the first warp door. The first door you come to, door A, contains the Spring of Strength. Make use of it to restore all of your health. The next door you come to, door B, contains a life extending Jar. You may even wish to return to door A and restore you life to gain the benefit of the Jar immediately. Remove any Nyurus that you encounter here so that they don't become a menace when you need to dodge other enemies.

Once you are through the first warp door, collect the Magic Book behind door C. Then return to the surface and prepare to cross the first waterfall. At this point, up the three Nyurus will approach you. It is a good idea to make sure that as many of them are to your left as possible so that they don't interfere with your crossing. A fourth Nyuru may appear as you cross; do you best to avoid it if it appears from the right. Beyond the stone bridge, you will find door D, which contains the first Bound Ball that you can collect. Be sure to grab it as it will be useful against the boss of this stage.

Beyond warp door W2, you must now cross two waterfalls. While you don't have to deal with Nyurus above the waterfall, you'll have to contend with Hop Eggs and Nigitos which are far more dangerous to Lucia. Do your best to jump over them and generally avoid them as much as possible, even if it means backtracking and scrolling them off the screen. Once you reach the boss room behind door E, carefully avoid any fireballs that may be falling from the surface above. Even after you defeat the boss and approach the goal, you must still be cautious of any Nigitos that may appear along the way.

Boss: Pera Skull
Compared to the previous stage bosses, this single Pera Skull is a piece of cake. You actually have many methods at your disposal to defeat it easily. The first is with your newly acquired weapon, the Bound Ball. While the Bound Ball has the possibility of bouncing it's way up to the Pera Skull, you can manually aim it upwards by holding while you fire. Using the Bound Ball, you can defeat it in six hits. However, if you manage to catch it low enough to the ground, you can actually slice the Pera Skull with one strike of the Flame Sword. And if that weren't enough, you could use the Magic Bomb and detonate it directly beneath the Pera Skull. It only takes approximately three bombs to defeat it. The general threat of this boss is low, so take your time and learn the method that works best for you. Don't forget to collect the Ball from the inner chamber before you proceed to the goal.
