The answer before the background

Our recommendation

Loop hero resources are named materials rather than a universal coin, gem or diamond wallet. Common fragments combine into complete resources such as Stable Wood, Preserved Rock, Stable Metal and Food Supply. Advanced goals use Orbs of Expansion, Immortality, Afterlife, Crafts, Evolution and Unity, plus Astral Orbs, Metamorphosis and Books of Memories. Choose the target building first, then farm the tile, enemy or transformation that produces its exact missing material.

Match every material to a repeatable cause

The resource goal determines the danger budget

A farming deck is not simply the deck with the most spawners. For Stable Metal, inventory flow and safe repeated circuits matter. For Orb of Expansion, groups must be large enough to meet the source condition without overwhelming the class. For Astral or Unity materials, the correct enemy type and chapter are more important than raw kill count.

Write a retreat rule before the expedition. A material only advances the camp if enough of it returns. Once the target resource is complete or the health trend turns negative, bank the result. The current retreat screen shows the retention consequence; a guide should never hide that cost behind a promise of infinite farming.

Coins, gems and diamonds are usually the wrong question

The released game does not organize camp construction around a generic premium-gem wallet. Searchers using coin, gold, money, crystal, gem or diamond language are often looking for materials or an easier farm. Identify the named building and required resource instead of inventing a currency balance.

Alchemy can convert material value after the appropriate camp service exists, but conversion has costs and does not erase source planning. Use surplus only after preserving the resources needed for current prerequisite chains.

Common questions

How do I get Stable Metal?

Scrap Metal combines into Stable Metal; equipment overflow is a repeatable source, so manage inventory without sacrificing essential build pieces.

How do I get Orb of Expansion?

Community documentation ties it to fights with at least four enemies, with larger groups improving the chance. Build only as much pack pressure as you can survive.

How do I get Astral Orb?

Collect Time Shards from the appropriate later-chapter enemy types, then combine them. Verify the exact source list in the current encyclopedia.

Are there coins and diamonds?

Those generic terms do not describe the core material ledger. Start from the camp upgrade and its named requirement.
