Hint: Babble Land, After you get the Godbird Soulstone, fly to the area overlooking the desert. Tere you will find a lot of metabbles, sometimes as many as eight in one battle. Unfortunately, there are some other powerful monsters in that same region, so you need to use caution when babble hunting.
Hint: Forge Metal King Shield, You require the Ruinous Shield, Orihalum, and Saints Ash for this armor. Purchase the Saints Ash from the Dragovian Village after clearing the game once (and do a game clear save, or you'll want to defenestrate yourself after your PS2). The Orihalum is earned by collecting medals and trading enough of them to the island princess north of Peregin Quay. The Ruinous Shield may be found in the air-only part of the island where the Doulmagus was killed (at the mirror puzzle).
Hint: Forge Liquid Metal Sword, Get the rusty sword from Trodain. Earn a slime crown by fighting metal slimes or King slimes. One slime crown is inside the well on the hilltop hut. The final ingredient, Orihalcum, is difficult to get with an external cheat device. The easiest source is to accrue 83 medallions and trade them to Minnie for the item. Drop all three ingredients into the alchemy pot for the rare Liquid Metal Sword.
Hint: Fighting Metal Slimes, The best way to kill Metal Slimes is to use attacks that inflict critical damage. The hero's Lightning thrust ability performs a critical attack on these enemies. Another method is to use Falcon Blades, which allows you to attack twice -- this theoretically doubles your chances of inflicting a critical blow.
Hint: Forge Thieves Key, Put the rusty sword and the iron nail (at Paraguay Quey) to make the Thieves' Key. This item lets you open any locked chest.
Hint: Level Up The Dingaling Method
After you're able to defeat the Jargons in the Maella Region in a couple of hits and the Dingalings only cause 1 to 2 HP of damage to you, you'll be able to get as much XP as you could possibly want.
All you have to do is run around (or Whistle) until you run into a Dingaling. Do not kill the Dingaling, you should kill all other monsters that assist a Dingaling and leave only one Dingaling on the field. Have Jessica, Hero, and Angelo (if applicable) defend and Yangus Psyche up.
When the Dingaling calls for backup, attack with Yangus for an easy kill. Keep doing this and the Dingaling will keep calling Jargons to help it, and you can kill them in one move. If the Dingaling calls for backup before Yangus psyches up enough, just have your weakest attacker assist him.
Hint: Forge Timbral of Tension, For this item, you require the Sun Crown, Magic Beasts Hide, and Tough Guy Tattoo. The first two items are the ones that are hard to find.
Bag the Sun Crown by finding the Skull Helmet in the second area of the Heavenly Dias, near a dragon skull. Combine it with an Urn of Saints' Ashes to make it. The Heavenly Dias is located by accessing the extra dungeons and Dragovian Sanctuary. Go to Chateau Felix and use the Godbird Stone to land on the platform to portal with the item.
