Loot Chests

Solarpunk loot chest reference for chest families, possible item links, exploration planning, and Treasure Hunter achievement cleanup.

Loot chests matter because they turn exploration into material progress and feed the Treasure Hunter achievement. Treat them as airship-route targets, not random side objects.

How Chest Loot Rolls Work

If a chest is configured as fixed loot, the game returns the fixed inventory directly.
Otherwise the chest starts from empty return slots and verifies that its normal loot table is not empty.
The game can fill one special slot by making a weighted pick from the special loot table.
For normal slots, the game walks the loot slot chance list. A chance value of 100 or more is guaranteed; lower values roll a random number from 1 to 99.
When a slot succeeds, the game uses a weighted loot-slot pick and copies that item and drop amount into the returned inventory.

The table below lists the confirmed possible item pools. It does not invent exact percentages because the available game data confirms item pools and roll structure, but not the exact slot odds or stack amounts.
