How to Complete the Mysterious Note Quest in Xenoblade Chronicles 2

The Mysterious Note is an engaging side quest in Xenoblade Chronicles 2 on the Nintendo Switch. Located within the beautiful Kingdom of Uraya, this quest requires players to brave environmental hazards, execute a precise jump off a giant water slide, and defeat a level 22 Driver named Erebos.

Completing this quest is highly recommended for early-game progression, as it awards valuable Skill Points (SP) and a useful accessory.

Step-by-Step Quest Walkthrough

Use this quick-reference sequence to navigate the main steps of the quest:

1Go to the Acid Gullet
2Pick up the Note Fragment
3Skip travel to Soulcrown Summit
4Slide down the water slide and jump
5Open the chest for the Broken Knife
6Find Erebos near Eight-Rock
7Defeat Erebos in battle
8Speak to Erebos to complete the quest

Step 1: Retrieve the Note Fragment

To begin the Xenoblade Chronicles 2 mysterious note quest, you must first find the item that triggers it.

  • Head to the Acid Gullet area, which is located directly beneath the Windpipe Deeps in the Kingdom of Uraya.
  • Environmental Hazard: The acid pools in the Acid Gullet will rapidly drain your party's HP during exploration and combat. Move quickly, grab the Note Fragment glowing on the ground near the acid, and retreat to safe, dry land.

Step 2: Reach the Cleansing Spring Chest

The Note Fragment points you toward an isolated rocky outcrop in the Cleansing Spring. Reaching this island requires some precise platforming:

  1. Skip travel to Soulcrown Summit.
  2. Look downward to spot a cavern opening in the shallow waters below.
  3. Drop down, enter the cavern, and follow the path as it slopes downward and turns into a fast-moving water slide.
  4. The Jump: As you slide down, you must jump to gain enough momentum to clear the gap and land on the isolated island. Many players find success by jumping slightly early during the slide rather than waiting until the absolute edge.
  5. Once you land successfully, open the chest during the brief cutscene to retrieve the Broken Knife.

Step 3: Confront Erebos

With the Broken Knife in your inventory, you can now track down its owner, a level 22 Driver named Erebos.

  • Location: Travel to the Stomach area of Uraya. Erebos is standing near the waterfall, right next to the Eight-Rock skip travel point.
  • The Battle: Speak with Erebos to initiate the fight. Be cautious during this encounter; Erebos utilizes knockback attacks that can easily push your characters off the narrow rock platform. Position your Driver with their back to the solid wall or the center of the platform to prevent falling.
  • Completion: After defeating Erebos, speak to him one final time to wrap up the quest.

Quest Rewards

Upon talking to Erebos after the battle, the quest will instantly complete. You will receive the following rewards:

  • Gold: 1,060
  • SP: 107
  • Items: Activity Amulet
  • EXP: 0 (Note: This side quest does not award any Experience Points).
