33 Mini Reactor is an advanced power component in Starsand Island, produced at the Energy Converter. It is one of the late-game crafting materials that gate the highest tiers of processing stations. Mini Reactors are not consumed in everyday cooking; instead they act as a key upgrade part for taking core production machines to their final tier. The Energy Converter that makes them is unlocked deeper into Crafter profession progression, and its blueprint is bought from the General Store.

1010 Starflare Crystal is a rare crystal gathered in the Moonlit Forest, so the Starflare Crystal supply is usually the bottleneck. Magnets and High-Performance Wire Sets are produced from refined ores and are easier to keep in stock once your mining loop is running.

1717 Because each tier-III upgrade is a one-time cost, you only need a handful of Mini Reactors across an entire save. Plan a single Starflare Crystal gathering trip around producing enough for all three station upgrades rather than farming them continuously.

2121 Stockpile Starflare Crystal while exploring the Moonlit Forest. It is the limiting ingredient for every Mini Reactor.Build the upgrades in priority order. Furnace III usually pays off first because top-tier ingots feed into so many later recipes.Keep Magnets and High-Performance Wire Sets pre-made in a chest so a single Energy Converter run can output all the Mini Reactors you need at once.Mini Reactor is a tier gate, not a consumable. Once your Furnace, Cutter, and Worktable are all at tier III you will rarely need more.
