Cast a Magnet Magnet Upgrades Priority

Every Cast a Magnet session funnels into the same question: where should this Cash go? Sweg Magnets’ incremental loop sells heavy finds so you can upgrade the magnet’s Real Power, Rope Length, and Luck. Buy them in the wrong order and you will own an expensive lucky magnet that cannot reach deep water or lift the rares Luck finally rolls. This guide gives a practical priority stack for early, mid, and late progression, plus checkpoints that tell you when to stop shopping and go cast again.

New players should finish getting started and be able to land perfect casts before min-maxing. Upgrades multiply clean play; they do not replace it.

The three core upgrades

Real Power

Real Power is your pull strength. Heavier items are worth more Cash, but only if the magnet can secure them. Under-powered casts bounce off the best weights and leave you selling light scrap forever. Power also makes mid-tier junk faster to clear, which raises Cash per minute even before legendaries appear.

Rope Length

Rope Length is your reach / depth. Cast a Magnet’s fantasy of “upgrade your magnet to go further” lives here. Extra rope opens water bands and cast distances the starter kit cannot touch. Without rope, Luck rolls on a shallow table and Power has nothing heavy to grab.

Luck

Luck raises the odds of rarer finds and pairs with potions, mutations, merchant stock, weather, and index bonuses. It is the most exciting stat on the sheet and the easiest to overbuy too early. Luck shines after you can already perfect-cast into rope-unlocked water with enough Power to keep heavy results.

Community tooling lists these three names explicitly (Auto Buy Upgrades targeting Real Power, Rope Length, Luck), which is a strong signal they are the permanent Cash sinks that matter.

Early game priority (first Cash spikes)

Goal: make every cast produce sellable weight quickly.

1. Real Power — buy the first affordable ranks until medium items stop feeling contested.
2. Rope Length — unlock the next obvious water band / farther cast.
3. Small Luck touch — one or two ranks only so you notice rare tags without starving power/rope.
4. Return to casting — ten to twenty perfect casts before the next shopping spree.

Avoid dumping an entire inventory of Cash into Luck while your rope is still starter-length. Also skip cosmetic flex until the three stats have moved at least once. If you joined the Roblox community for free Luck Potions, save those vials for after this first power/rope pass — details in luck and potions.

Mid game priority (stable loop)

Goal: convert perfect casts into rare hunts without soft-locking Cash.

1. Keep Rope Length near the water you actually farm. If you stand at a new shoreline and casts feel short, rope is the buy.
2. Raise Real Power whenever heavy rares escape or sell values stall despite good timing.
3. Push Luck in chunks before a focused session, then cast — do not alternate one luck rank between every throw.
4. Budget for merchant potions and a display slot if trophy items are auto-selling; see display base.
5. Claim bounties / dailies before big purchases so free Cash reduces shop regret.

Mid game is also when players open the tier list to compare magnets or loot priorities. Use those ranks as a shopping hint, not a substitute for feeling your own power/rope breakpoints.

Late game priority (pre-rebirth and post-rebirth)

Goal: squeeze the current magnet sheet, then reset cleanly.

• Stack Luck harder once rope and power no longer gate the content you can see.
• Keep emergency Cash for merchant mutation vials during weather events.
• Stop over-upgrading stats that will wipe on rebirth if community reports say they reset — plan with the rebirth guide.
• Prefer buys that accelerate the next climb (permanent unlocks, index progress, display keepers) over vanity.

Late sessions often mix Auto Buy Upgrades style play with manual perfect casts. Even if you never use scripts, thinking in “buy power → buy rope → buy luck → cast block” cycles keeps the economy honest. Feature context for automation lives on scripts; learn the manual order first.

Priority cheat sheet

| Phase | First buy | Second buy | Third buy | Hold potions until… | | — — | — — | — — | — — | — — | | Early | Real Power | Rope Length | Light Luck | Perfect cast feels consistent | | Mid | Rope to new water | Real Power for heavies | Luck chunks | Merchant stock + weather align | | Late | Luck / event needs | Power gaps | Rope gaps | Pre-planned rare hunt or index push |

Cash discipline rules

1. Never shop mid-minigame — finish the cast, then open upgrades.
2. Sell junk in batches so you see a real Cash number before buying.
3. One breakpoint per trip — either unlock rope water or solve a power problem or prep luck, not all three with 100 coins left.
4. Test after purchase — if twenty casts feel identical, you bought the wrong stat.
5. Watch UPD notes — updates may retune costs; re-check priorities after big patches.
6. Codes are bonus Cash — when promos exist, redeem via how to redeem and dump into the current phase’s top stat, not random cosmetics. Track live strings on codes.

Magnets versus upgrades

Some Cash sinks buy new magnets rather than leveling the three stats. Treat a magnet swap like a breakpoint purchase: only buy when the new magnet’s baseline power/rope/luck clearly beats your upgraded starter after a fair test. If the shop price equals dozens of stat ranks, run the math against your current perfect-cast Cash rate. Tier opinions belong on the tier list; this page stays focused on the universal Real Power / Rope Length / Luck triangle.

Example first-hour spend path

1. Sell starter junk → buy first Real Power ranks.
2. Cast until bag fills → sell → buy Rope Length.
3. Perfect-cast block on the new water.
4. Sell again → sprinkle Luck.
5. Claim community potions but do not drink yet.
6. One more power or rope rank if heavies still contest.
7. Drink potions, hunt rares, display keepers, sell the rest.

Follow that rhythm and your magnet sheet will tell a clear story instead of a random receipt. When the story ends in soft caps, graduate to rebirth planning — not panic Luck spam.
