To get the Mystic Mirror in Fisch, you need to unlock Merlin’s crafting first, then gather three ingredients and craft it with him. The core steps are: finish Merlin’s questline, buy a Magic Mirror from the Traveling Merchant, get a Magical Crystal Geode from the Mineshaft, and get a Magical Glass Diamond from the Overgrowth Caves, then return to Merlin to craft the item.

Quick Scoop

  • Unlock Merlin crafting. Sources say the Mystic Mirror is tied to Merlin and becomes craftable after progressing Merlin’s quests; one guide says you must be above level 30 to talk to him, while another says you need to finish Part 2 of his questline.
  • Get the Magic Mirror. Buy it from the Traveling Merchant for about 50,000 C$.
  • Get the Magical Crystal Geode. Fish in the Mineshaft and use Merlin’s Staff/Rod to trigger the magical mutation.
  • Get the Magical Glass Diamond. Fish in the Overgrowth Caves with Merlin’s Staff/Rod so it becomes the magical version.
  • Craft it with Merlin. After collecting all three items, talk to Merlin and choose the Mystic Mirror craft option.

Fast Route

  1. Progress Merlin’s questline until crafting is unlocked.
  1. Buy the Magic Mirror from the Traveling Merchant.
  1. Go to the Mineshaft and fish until you get a Magical Crystal Geode.
  1. Go to the Overgrowth Caves and fish until you get a Magical Glass Diamond.

Useful Notes

  • The magical versions matter; normal Geode or Glass Diamond won’t count.
  • The Mystic Mirror is basically a warp tool: it lets you set a waypoint and teleport back to it later.
  • The Merchant appears randomly, so you may need to wait for his spawn.

Bottom line

If you want the shortest answer: complete Merlin’s quest, buy the Magic Mirror, fish the two magical materials with Merlin’s Staff, then craft the Mystic Mirror from Merlin.
