To get the Forest Lord skill for Prier, you must first have the Forest Lord's child, obtainable by getting the Bad Ending for the Chapter 3. Go back after the chapter, to the last map of Meuniere Forest to get the Lord's child to join you. After getting the Lord's child, train him up to level 20, and then return to the last map of Meuniere Forest again, a cutscene will follow and the Lord's child will leave the party but in return, let's Prier gain the "Forest Lord" Skill which summons the Lord's child in battle, and he transforms to the size of the former Forest Lord and do some slashes.
This skill costs 60 sp to use but is a pretty decent skill. Note that you cannot lose the Child during training(happiness level 1) or you will not be able to get the skill forever. Also, you have to train him to level 20 BEFORE getting on Homard's Ship or it will be a long time before you can continue the procedure of getting the skill. This is because once you board Homard's ship, you will not be able to access the main land, therefore not being able to access Meuniere Forest.

Go to the battle map view. Switch out any item that is currently equipped with an item that increases your movement. Use your turn to move, then switch your items back to their original positions. You have now moved more than normally possible.

In Chapter 4, you will have the opportunity to receive a special ending, along with the Angel Shoes. To do so, you must defeat the Monster, rather than leading it to Mt. Tarte. As difficult as this may sound, it actually is not all that hard. First, catch a bear or two, as their Bear Bash skill is useful. Then, level build. If needed, go to the Dark World and level build until you are about level 20 with your entire team. If you still cannot defeat the monster, continue to level build. This can take some time, but is worth it. The Angel Shoes add 3 to your movement, 200 to speed, and 80 to defense, as well as increasing your speed attribute by 3.

Attribute skills are very important, however they are difficult to build up. Try building them up slowly. Have certain characters excel greatly at certain skills, but still have good stats overall. The way to do this is with the use of the Raise/Elevate Atk/Def/Spd/Int/etc. Equip your character with as many of these items as possible and fight low level enemies in order to raise it to extreme levels. If done correctly, you can sometimes gain over two skill levels in one battle.

Go to the Orphanage in the last chapter and talk to the first girl you see. She will give you the Cactus Sword.

Be wary of your characters levels. It is very easy to level up one character then never let any of the other characters level up. This is a bad idea, because you will eventually find enemies where it is quantity and not quality that will win the battle. Try to level up your characters somewhat evenly, especially if your only leveling Prier. Almost all her abilities are only able to attack one enemy at a time, no matter how strong her attacks are.

Convert many monsters, not only for the Dark World, but also in order to use as distractions. You will find levels where it is better to run than to fight.

Enter any map where the enemies do not rush into your characters (i.e., you can start far away from the spawn point). Start summoning your characters and have them use their Special Skills on each other until they kill each other. This will raise your Dark World level and give you skill points and even experience points. Leave at least one character alive, then exit the map. Repeat the process on the same map until you achieve the desired skill level and Dark World level. You can also level up your items by using Purify on nearby Dark Crystals before exiting the map.
