Upon obtaining 5,000 stardust find your way to the furthest north-east part of the shops at ::home to find Stardust Reward Shop. Purchase enchanted lockpick dust from her for the 5,000 stardust.
Step 4: Use the enchanted lockpick dust on the crude lockpick to create a galactic lockpick.
Step 5: Use the magical passion flower on the galactic lockpick to create an aeonian lockpick.
Step 6: Equip any pickaxe and right-click on the magicians instructions to teleport to a cave. In the middle of the cavern will be a rockslide that could be mined for half rocks and uncharged orbs. You can drop the half rocks and mine until you have obtained 20 uncharged orbs.
Step 7: In the north-east most part of the cavern you will find a closed chest. Use your aeonian lockpick on it to find a yin-yang tab.
Step 8: Consume the yin-yang tab to teleport to the spirits lair.
