I wonder if Frieren has contingency against perfect copies. They are mimics but on much higher level.

There are few interesting world building tidbits this episode that makes me go: "Hmmmm… " What are the coins? Are they something akin to geocache log? Was that crystal a dungeon core? What happened to that one lone wolf when facing a copy of themself? Will the golems be strong enough against copy of frieren?

The pipe organs in the soundtrack really give that dungeon synth vibe.
