Skull Guitar (Puzzle)

The Skull Guitar Puzzle is a secret puzzle in the Third Sea that allows players to craft the Skull Guitar. The puzzle consists of several challenges that must be completed in order before the Weird Machine becomes available.

Tip: Visit the Gravestone before starting. If candles are lit around it, you meet the requirements and can begin the puzzle.

Puzzle Walkthrough

Step 1 – Pray at the Gravestone

Travel to the Gravestone at the Haunted Castle.

  • Pray during a Full Moon at night.

  • The screen will briefly turn black.

  • When it returns, the candles around the Gravestone will be lit, indicating the puzzle has begun.

Step 2 – Defeat the Living Zombies

Kill six Living Zombies simultaneously using a single attack.

Recommended Strategy

  • Use Buddha to gather all six zombies.

  • Hit each zombie once, then group them together.

  • Finish them all with a single M1 attack.

Other useful options include:

  • Light (gather enemies with M1s and finish with V)

  • Magma (high NPC damage)

  • Human or Cyborg races for increased damage

Tip: Avoid attacks with heavy knockback, and keep Instinct active to survive while gathering the zombies.
