Idle Legions · Field Guide
Follow reward sources, compare known and unknown rates, and explore fusion odds.
Reward sources use different rules. A chest's contents, an enemy's reward and a forge result are separate rolls; their percentages cannot be substituted for each other.
1 · Earn or collectCampaign rewards, act keys, Abyss encounters, World Boss contributions or a chest you already own.
2 · Resolve the rewardThe server supplies the applicable pool, odds and any guarantee. Opening a chest is a separate action where required.
3 · Receive and inspectCheck the bag or the activity's delivery route. World Boss rewards arrive by mail. A full bag blocks chest opening.
Schematic sequence, not a measured drop distribution. Not every reward passes through a chest.
Enemy chest drops and stage rewards feed the chest bag. Opening a chest can return equipment or a gem, with possible bonus rewards.
Chest tiers: Common, Rare, Epic, Legendary, Unique and Boss.

Order shows quality, not likelihood. Equal card sizes do not mean equal odds; unknown percentages are not zero. Chest pools, pity counters and fusion guarantees can differ by operation and account state.
