Refinement Basics — What You Are Gambling On
Refining increases equipment +level, boosting base attack or defense. Each click at the blacksmith consumes ores, zeny, and — above safe thresholds — risks breaking the item back to +0 or destroying it entirely depending on season rules. Players ask How does refine RNG actually work? The answer: each level has a published or datamined success rate; failures can downgrade or break unless protected.
Think of refine as incremental power with escalating variance. +1 to +4 is tutorial territory. +5 to +7 is core progression. +8 to +15 separates whales, patient farmers, and risk-takers. Read Safe Refinement +15 for milestone terminology before spending rare ores.
Success Rates and Pity Systems
Low levels hover near comfortable 60–80% success; high levels drop sharply. Some seasons add hidden pity or "safe refine" tickets guaranteeing +5, +10, or +15 stops — watch Current Events for ticket sources. Without pity, expected attempts follow geometric distribution: lucky players hit +10 fast, unlucky players fund the economy.

Protection Items and When to Use Them
Protection stones (names vary by patch: Refine Protection, Blessed Ore, etc.) prevent breakage on failure — you still pay materials, but gear level does not shatter. Rule of thumb: always protect +8 and above on best-in-slot weapons; optional +5 to +7 on budget alts; never protect throwaway testing gear unless materials are cheaper than re-buying base item.
Event bundles often discount protection — hoard for weapon pushes, not armor cosmetics. Merchants can flip discounted protection during Merchant seasons; know market floors before arbitrage.
Economy RNG Beyond Refine
Refine is not the only RNG sink. Card albums, enchant rerolls, and gacha cosmetics share psychological traps. Separate power RNG (refine, enchants on BiS gear) from cosmetic RNG (costumes). Power RNG should always tie to measurable DPS or survivability gains — simulate with ASPD Calculator or parse MVP clear times.
Cards and enchants are covered in Cards & Enchants. Farm deterministic materials first (ores, zeny) before rolling gacha boxes for +refine equivalents.
How to Refine Without Going Broke
Set stop rules: Example — "Main weapon stops at +10 this month." Farm before you click: Run Daily Routine ore maps until planner estimates are 80% met. Use safe milestones: Stop at +5 for armor sets until weapon hits target. Redeem codes: All Redeem Codes often include ore pouches.
Psychological trap: chasing losses after a break. Log off, craft on an alt, return next day. The blacksmith is designed to drain excess zeny — disciplined players still progress by targeting +7 weapons and efficient cards instead of lottery +15 streams.
Advanced: Refine Timing and Meta
Patch weeks may adjust ore drops or success rates — recheck community notes after maintenance. New gear tiers invalidate old +15 vanity pieces; timing upgrades with content releases beats blind pushing obsolete weapons.
Gunslinger and Assassin metas reward weapon refine more than Mage staffs early; Priests benefit from survivability refine on shields and garments. Align spending with your class roadmap in All Classes & Builds. When RNG frustration peaks, remember: stable +7 with good cards clears most PvE — perfection is optional.
