Sublight Caches, Markets & Rerolls Guide
How Sublight caches, minimum rarity, markets, rerolls, skip choices, and reward economy work after the major demo progression patches.
Treat caches and markets as build filters, not vending machines. Cache labels can indicate reward type and minimum rarity; uncommon and rare caches cost more; markets now spawn every event cycle with only one active at a time. Spend currency when the choice strengthens your current build, and reroll when all offered options are genuinely off-plan.
Cache quality and labels
Patch 0.17.1 redesigned cache logic, added reward labels such as minimum rarity, and added higher-rarity caches at higher cost. This fixes an important decision problem: you can judge whether the chest is worth the spend before opening it.
Markets
Patch 0.18 increased market frequency to every event cycle, with only one active market at once. That makes currency preservation more relevant. If a mediocre cache will empty you immediately before a market, skipping can be the stronger choice.
Reroll discipline
Reroll when the offered choices miss the build and the cost leaves room for the next purchase. A useful first choice can be stronger than paying repeatedly for a perfect one. The best roll is the one that compounds what your ship already does.
Boss loot skip
In 0.18, skipping boss loot triggers a level up. That means “none of these uniques fit” is no longer necessarily a dead choice.
Pirate-event currency and the corrected loot pool
Pirate Frigate and Pirate Cruiser events in 0.20.02 drop a chest containing run currency. Use it to fund a cache or market choice that supports your existing build. Treat the payout as encounter loot, not an Armoury-credit refund or a guaranteed specific weapon.
0.20.01 fixed Fleet Support never appearing in loot pools and a market sometimes spawning inside the second-level mountain. On a current build those are repaired bugs, rather than rules that Fleet Support is unobtainable or a mountain market is an intended destination.
The 0.20.0 reward-table change still matters: lower-tier chests stop offering weapons as a run progresses. Read the chest’s reward label, and avoid spending solely to hunt for a gun that is no longer in that reward pool.
