Stage I

Luck Efficiency · High average rerolls on Snowy Isle. No limited-time equipment required.

• Stat priority: Luck > Shake Strength = Shake Speed > Capacity > Dig Speed.
• Museum is a suggestion rather than necessity at this stage.
• Modifier ranking for this build: Treasured 2L > Perfect LCW = Voidtorn LC > Mutated LDM > Iridescent L > Cosmic CA > Lunar SPK > Electrified SP > Shiny A = Glowing P > Scorching D > Pure S.
• Crystalline W and Irradiated M are useless for this build.
• If your Mythril Rings have no mutation, use Prismatic Moon Rings — they're easier to mutate.
• Fallback Dig-Speed ores: Common: Blue Ice 40 / Platinum 40 / Amethyst 20; Uncommon: Titanium 40 / Sapphire 20; Rare: Lapis Lazuli 30 / Glacial Quartz 40 / Azuralite 30; Epic: Iridium 40 / Cobalt 40 / Borealite 20 / Aurorite 30; Legendary: Aquamarine 20 / Aetherite 20.

Size Boost · High Size Boost on Snowy Isle. Collect big ores for money and Museum buffs.

• Goals: big ores for big money + Museum-sized ores granting max buffs.
• Modifier ranking when Perfect LCW / Crystalline W aren't available: Treasured 2L > Mutated LDM > Voidtorn LC > Iridescent L > Cosmic CA > Lunar SPK > Electrified SP > Shiny A = Glowing P > Scorching D > Pure S.
• Use a Solar Magnifier (and Infernal Idol at Caldera Island) to increase Museum-quality ore drops.
• Use this build alternately with the Sell Boost build.

Sell Boost · Selling-only loadout for Stage I. No limited-time equipment required.

• Equip right before selling a full backpack.
• Use a Size Boost build to collect the ores.
• Some museum entries are above Stage I — included because you might luck onto them.
• More parts of the build covered = bigger money.
