The Adventures of Elliot: Leytstaf Sword location in the Water Ruins

The Leytstaf Sword is the final sword upgrade in The Adventures of Elliot: The Millennium Tales, and it is far more than a stat boost. It carries a powerful charge attack and acts as a hard requirement for the game’s two stronger endings. Although it appears to be lost after your fight with Minister Kaifried, the blade lands in the water and waits for you deep inside the Water Ruins.

Quick answer: Beat Primordial Entity Kaifried, get the Diving Manual from the Water Shrine (Age of Magic) by defeating Frauki Capo, then complete the Water Ruins in the Age of Reconstruction. The sword sits behind a Blue Door near the end of that dungeon.

Requirements before you go for the Leytstaf Sword

Two things gate this sword. You cannot reach the deeper parts of the Water Ruins without the ability to dive, and the dungeon only opens up once you are near the end of the main questline.

Requirement	How to get it
Progress past Minister Kaifried	Defeat Primordial Entity Kaifried in the main story.
Dive Underwater ability	Obtain the Diving Manual after beating Frauki Capo in the Water Shrine (Age of Magic).
Dungeon access	Head to the Water Ruins in the Age of Reconstruction.

Water Ruins route to the Leytstaf Sword

The Water Ruins run on water-level puzzles. You raise and lower the water by hitting Orbs, then dive under walls when the level drops. The path is easy to lose if you wander, so follow the sequence below in order. Bring healing items or enough tul to revive, since there is at least one mandatory fight on the way.

Start in the main room and hit the center Orb to raise the water. Travel northeast and then south into the room in the southeast, and hit the Orb there to lower the water again.

Take the stairs in the room directly north. Swim west and dive under the wall on the west side, then head south to the next Orb room. Lower the water, move east and then south across the platforms, and use the stairs in the southeast.

Go west in this room and hit the Orb to raise the water. Dive under the wall to the north, then flip the Orb in the northeast to lower the water.

Follow the path south and back west to the far-west room in the center. Climb the ladder to the Orb above it, hit it, dive under the wall to the north, and hit the Orb in the northwest corner.

Move east into the next room, clear out the frogs, climb the ladder, and open the blue chest to grab the Blue Shrine Key. You need this key for the final door.

Head back west, hit the Orb to raise the water, and dive south. Hit the Switch in this room, walk east, then go north through the center. This is where you fight the room’s enemies.

Climb the ladder on the right, hit the Orb, and open the Blue Door with your key. Open the chest behind it to claim the Leytstaf Sword.

How to confirm you have the Leytstaf Sword

Opening the final chest adds the Leytstaf to your sword slot as the three-star, “ultimate” tier blade. Once it is in your hands, the three Cat Sages will speak with you, since they refuse to acknowledge Elliot without it. Completing the Sage steps then unlocks the Mystic Seal super charge attack, which is the move tied to the better endings.

Why the Leytstaf Sword matters for endings

The blade is technically optional, but skipping it locks you out of everything except the Bad Ending. With the sword and its Mystic Seal attack, you can seal the Beast of Enmity for the Standard (Happy) Ending, and it is a mandatory first step on the longer True Ending path.

Ending	Leytstaf Sword role
Bad Ending	Not needed. Defeat the Beast of Enmity without using the Mystic Seal.
Standard / Happy Ending	Required. Land the Mystic Seal as the final blow on the Beast of Enmity.
True Ending	Required first, followed by the Sages, Mao’s Pendant steps, cats, and the final battle.

Grab the sword as soon as you clear the requirements. It is the difference between a single bleak ending and the two that actually close out the thousand-year story.
