Which Path Is Best? (Emerald Value vs. Move Budget)

Matches the gallery order — sorted by Emeralds per Move (highest first).

Lowest Move Count (limited Explorer’s Moves)

  1. #1 — 19 moves → best efficiency by far; includes Sapphires ×20.
  2. #7 — 17 moves → If you just need Elemental Catalyst.
  3. #8 — 16 moves → quick Primal grab; lowest EPM.

Highest Total Emeralds (sheer volume)

  1. #5 — 220,748.71 (52 moves)
  2. #3 — 197,146.45 (42 moves)

Methodology & Assumptions

Data sources. Values use the same pricing sheet as our other pages. Screenshots are simulator runs on the Cascade layout.

How we score. For each path we total the emerald-equivalent of all rewards, then compute Emeralds per Move (EPM) = Total Emerald Value ÷ Explorer’s Moves. We rank by EPM for efficiency and also show total emeralds for volume-focused players.

Interpreting the rankings. #1 (19 moves) is the best EPM because adding Sapphire Medallion ×20 spikes value. #2 (26 moves) layers more loot with only a small efficiency drop. #3–#5 (42/39/52) are the high-budget choices; #5 wins on raw total. #6 (30) and #7–#8 (17/16) are fallback routes when you want to skip sapphire coins.
