Probably won't be making a printed guide, might make a video walkthrough and put it on youtube though.



For the Changeling Cave specifically, I'll admit that the game's difficulty curve becomes a bit of a wall there. My advice: make sure your white/red mage knows cure, cure2, harm, and harm2. Harm and harm2 are good against undead enemies. Get your fighter the Iron armor and Silver sword. Get the rest of your party Copper collars. Getting all of this stuff is very expensive so you'll have to grind quite a bit. This is good because it'll mean your characters are leveled up enough to continue (level 9 should be plenty). You can either stick with grinding lower level stuff in the ocean and around Griffonstone (Dogs are especially good for getting gold), or go to a harder area like the northern part of the Griffon continent and risk dying (but get dramatically more gold and experience). Also, make sure to buy a whole bunch of Pure (cures poison) and Heal (health potion) before making your attempt at the changeling cave.



When you're ready, head to the changeling cave. Your goal here is to retrieve the stolen crown. Most of the enemies here you'll be best off just running from, especially Scum. For undead enemies, use Harm and Harm2. When you enter the cave, go east at first. The passage will split between north and east, continue east. It'll then split between east and south, go south. At the end of the passageway there will be a room, enter it and go down the ladder inside.



2nd level: You start off in a room with multiple doors. Exit the room through the west-most door and head south. Past the pillars there will be a passageway that turns back to the east, follow it. At the end is a downward staircase.



3rd level: In this level there are a bunch of rooms sort of sunken into the ground. The staircase you came down is in the northwest corner of the room. Many of the rooms have a chest: the crown is in one of them. IIRC, the correct room is the one to the southeast of the stairs (i.e. not the one immediately to the east and not the one immediately south, but the one between those two). I could be mistaken in this. Regardless, when you approach the chest you will have to fight changelings. You cannot run from them so don't waste turns trying. After beating them, IMMEDIATELY open the menu and use Heal. When you take another step towards the chest, you'll be faced with more changelings. Beat them and open the chest to get the crown. Again, open the menu and heal up. As you're leaving, you have to face the changelings one final time. Beat them and exit the cave the way you came in. Once out, go immediately back to Griffonstone to heal up and save.



Hope this helps!
