Krao Cave (Hard)

ExpeditionConquest

Krao Cave is rich in a special mineral called Krao, known for its ability to repel external forces. Lepharists conducted various experiments with Krao here and, during the Last War, created the powerful Berk, which played a key role in the conflict. But when Berk went berserk and lost control, the Lepharists sealed the cave and withdrew.

Evidence and limits

Hard is interpreted from the source name, a distinct recorded Hard energy-cube schedule, and the shared visible group, tier and currency category with Normal. The source DungeonDifficulty remains None. The Expedition interface places Normal and Hard under Conquest, but the row itself has no explicit Conquest difficulty field or verified live unlock condition.

Client acquisition listings do not establish reward quantities, drop chances or current availability.

Energy-cube outcomes retain source quantity ranges and separate package counts. Weights are not converted to drop chances or combined yields. Consumption limits, ceiling counters, zero-valued bounds and current claim availability require runtime interpretation; no automatic farming totals are calculated.
