The following dungeons give hints on the location of the Source of Evil:

- Friendly Forest
- Some Random Cave
- Sand in my Pants Pyramid
- Hot Foot Dome
- Slippy Slide Note
- The South Pole

Once you complete these dungeon review these notes to see if you can find the Source of Evil.

The hints provided from the dungeons listed in Hint #1 are:

"The Source of Evil is NOT visible, it must be found."
This means the dungeon is invisible but checking a square by pushing ENTER / SPACE / Z / "C" like you would a treasure spot will reveal it once you are in the correct location.

"You don't need to fly to find The Source of Evil."
There aren't many locations you can reach only by flying but it does mean you don't need the airship to reach it.

"The Source of Evil is on an island that has snow on it."
This hint helps more, there's only a few islands with snow on it but there's still a lot of area to check.

"The Source of Evil isn't adjacent to any water."
Another minor hint. This means the Source of Evil isn't on the coast or next to any rivers or lakes.

"The Source of Evil is not hidden in a forest nor adjacant to any trees."
This helps cut down on the areas to search but there's still a lot of area on islands with snow that isn't next to water nor trees.

"The Source of Evil hidden on the smallest island of the world."
The biggest hint, this specifies which island the Source of Evil is hidden on.

With all these hints check the world map and see if there's a location that meets all these criteria. There should be a very small amount of area to search, it won't narrow it down to a specific square.

The Source of Evil is hidden on the same island as Athabasca, #13 on the world map. It's specific location is here:

There are hints to the location of the Holy Grail hidden in dungeons. Clear the dungeons you can and see if you can find which hints point towards the location of the Holy Grail.

The hints from the following dungeons point to the Holy Grail's location:

- Chilly Hut
- Wild Woods
- Pete's Peak
- Sand is Rough Pyramid

The hints are:

"The Holy Grail is hidden on a distant island."

"The Holy Grail and Sacred Water are hidden inside dungeons."

"The Holy Grail is hidden in an endless dungeon."

"The Holy Grail is not hidden in the arrow that points north."

If you have explored the world with the ship or airship you have found three dungeons that list ??? as the number of encounters to complete them: Venezia, Iskenderun, and Konigs. These three dungeons can't be completed no matter how many battles you win and are on a distant island. Only one of these dungeons has the Holy Grail however.

The solution to the endless dungeon is also hidden in dungeons. Complete other dungeons and review your notes and try to find the hints that solve the endless dungeon.

The dungeons with the hints are:

- Hut of Villainy
- The First Tower

The hints are:

"The secret number is 3."

"The solution is to flee the next battle after winning a secret number of battles."

The Holy Grail is hidden in dungeon #19: Venezia. Enter the dungeon and win 3 battles, then enter your 4th battle. Retreat and instead of being kicked out of the dungeon you will find the Holy Grail and Venezia, Iskenderun, and Konigs will be marked as cleared dungeons.

There are hints to the location of the Sacred Water hidden in dungeons. Clear the dungeons you can and see if you can find which hints point towards the location of the Sacred Water.

The hints from the following dungeons point to the Sacred Water's location:

- Wild Woods
- Road to Nowhere
- Dezadeash Castle
- Lumberjack's Haven
- York

The hints are:

"The Holy Grail and Sacred Water are hidden inside dungeons."
So the Sacred Water is hidden inside of a dungeon.

"The Sacred Water is hidden in a dungeon with midbosses."
While not a hint towards the Sacred Water's location it is a hint that there'll be a big fight once you find it!

"The Sacred Water is on the main continent."
So whatever dungeon the Sacred Water is hidden in it is located on the main continent. But you probably already cleared them all at this point, so maybe it is a hidden dungeon?

"The Sacred Water is NWNNWNWSWSEE from the center of the marker."
There's a direct hint on the location of the Sacred Water, but where's the marker?

"The marker's shape is a '+'."
So somewhere on the main continent there is a marker in the shape of a '+', once you find it you can find the location of the Sacred Water. Check the world map to see if you can find it.

There is a '+' shaped set of mountains in the desert to the west of Primrose, near Sand in My Pants Pyramid.

From the middle of the '+' shaped mountains in the desert west of Primrose go north twice then west twice and check the square. You'll find The Abyss dungeon, clearing The Abyss will reward you with the Sacred Water.
