Walter's Medal Enhancement: +10 to +20 with 100% Success Rate

Once your Walter's Medal reaches +10, enhancement from +10 all the way to +20 has a 100% success rate when done at NPC Marche. The recipe shifts at this stage — instead of two matching medals, you combine one medal with an Advanced Enhancement Stone.

Quick Tips

  • The 100% success rate means no medals are lost — the only cost per level is one Advanced Enhancement Stone.
  • Getting your first +10 is the real milestone; beyond that, the path to +20 is purely a resource investment with no luck involved.
  • Even in the +10–+20 range, the failure recovery mechanic still applies: on any failure, you recover the highest-level medal used. Since this range is 100% success, this should never trigger — but it is good to know.
  • Stack Advanced Enhancement Stones before starting the +10→+20 run so you can complete it in one session.

FAQ

What exactly is the Advanced Enhancement Stone?
The guide refers to it as "Advanced [Stone]" in the recipe UI. Confirm the exact item name in-game at NPC Marche before purchasing from the Item Mall.

Is the 100% success rate guaranteed by the game or just historically observed?
The official guide explicitly states: "100% success rate for +10 up to +20 with NPC Marche."
