The Endu Shrine Gate Key is inside the lower Crypt on the Isle of Neasied. Get the Dagger Belt first, use a throwing dagger to activate the dungeon entrance switch, then descend to the stone table holding the named key.

Before entering the Crypt

This is an opening route for the released PC game. You do not need the Holy Sword Endu to collect the key; the key is one of the steps that leads to that sword. Begin from the knights’ camp and establish a save at the first Crystal Monument before exploring the coast.

The Dagger Belt is on the farther of the small coastal islands. Collect and equip it so you can use throwing daggers. Wait for a dagger charge before approaching the dungeon switch. See the saving guide if you are unsure whether visiting a monument has actually recorded your progress.

Open the dungeon door

From the opening monument area, take the uphill path toward the lower clearing with a large tree. The Crypt entrance is by the braziers. Look for a diamond-shaped opening beside the door and throw a dagger through it to operate the switch.

Do not assume every door in the clearing enters the Crypt. The opening area also has a return shortcut. Open a route back to the monument when you find it, then save before committing to the underground descent. That gives you an identifiable return point instead of a long, uncertain run after the key pickup.

Reach the lower key chamber

Use these landmarks to keep track of the descent:

  1. Go down the entrance ramp and clear space before advancing into the lower rooms.
  2. The northern side room contains the Wooden Club chest. This is a useful weapon detour rather than the key itself.
  3. Return toward the southern room with candles and a bowl of coins.
  4. Take the stairs down again and locate the central stone table in the lower chamber.
  5. Move close enough to read Endu Shrine Gate Key, then collect it.

The item name is your confirmation. Reaching a shrine-like room or finding a different chest does not complete this step. Before leaving, you can check the nearby Pandora Blade hidden room, which uses the key table as its starting landmark.

Return to the shrine

The exit route leads toward a lift. If its gate reports that it is too heavy, inspect the mechanism beside the gate rather than repeatedly interacting with the bars. Return to a Crystal Monument and save the key pickup.

Follow the coast back toward the Dagger Belt islands and continue to the fenced Endu Shrine. The key opens that shrine gate. Prepare healing items and a melee loadout before proceeding: the Shrine Guardian is the next obstacle, and defeating it opens the route to Endu.

If the key does not open a door

Check the inventory name and the door’s location first. This guide concerns the Endu Shrine gate, not every locked door on Neasied. If the item disappeared after loading, you may have loaded a save from before the pickup. Recheck the lower Crypt table before trying unrelated switches.
