To refine accessories efficiently in Seven Knights Re:BIRTH, use Random Refining with low-grade fodder until you land a high-impact legendary sub-option, then switch immediately to Fixed Refining to lock that affix while rerolling the remaining slots. Selling normal and rare accessories prematurely deprives your account of the bulk materials needed to cycle through substat rolls sustainably.

Random Refining vs. Fixed Refining

The accessory refining system alters or upgrades the bonus substat slots on high-tier rings and necklaces. The two methods serve distinct stages of the gear-crafting process:

FeatureRandom Refining (임의세공)Fixed Refining (고정세공)
Primary MaterialLow gold, normal and rare fodder accessoriesHigh gold, specialized refining materials
Slot BehaviorRerolls all unlocked substat slots simultaneouslyLocks chosen slots and rerolls only open slots
Optimal UseFishing for an initial high-grade affixFinalizing secondary and tertiary affixes
Main Resource RiskOverwrites all currently unlocked affixesRapidly exhausts premium currency and locks

Random refining functions as an exploration tool. Because all unlocked slots reset on each attempt, using it on an accessory that already holds an ideal roll risks erasing that value. Conversely, fixed refining protects high-tier affixes at a steep material premium. Applying fixed locks to low-tier or mediocre affixes quickly burns through gold and locking materials without yielding endgame-quality gear.

Managing Normal and Rare Fodder

Stockpiling normal and rare accessories provides the volume required to absorb unfavorable roll streaks. Consuming 100 or more fodder items across a crafting session creates repeated roll opportunities without cutting into high-grade synthesis materials.

To safeguard your inventory during bulk sessions:

  • Lock core accessories: Protect equipped jewelry and priority base items before entering the refining menu so they cannot be selected as fodder.
  • Filter low-tier gear: Reserve only normal and rare pieces that lack native high-grade substats for the refining pool.
  • Refine in measured batches: Process items in batches of 30 to 50 rather than selecting your entire reserve at once.
  • Stop on target hits: Monitor each outcome; halt the session the moment a desirable legendary affix appears instead of burning remaining queued fodder.

Identifying Sub-Options Worth Locking

Fixed refining costs enough that only affixes with immediate combat impact justify locking. Substats roll in tiers from common to legendary, but a legendary border alone does not make a roll optimal.

  • High-priority locks: Percentage-based attack boosts, critical strike damage multipliers, crowd control resistance, and revive or survivability triggers.
  • Skips or rerolls: Flat base stats and mismatched defensive options on damage-focused accessories.

If a legendary affix fails to support the equipped hero's battlefield role, treat the piece as an ongoing random reroll rather than committing expensive locking items to protect it.

Step-by-Step Refining Cycle

Follow this sequential loop to upgrade an accessory without wasting resources:

  1. Select a base piece: Choose a 5-star or 6-star accessory with foundational stats appropriate for your target hero.
  2. Execute random rerolls: Feed normal and rare fodder into Random Refining. Keep all slots unlocked during this phase to minimize gold expenditure.
  3. Check for a core affix: Stop random refining immediately when an elite legendary sub-option appears.
  4. Lock the targeted slot: Switch the interface to Fixed Refining and lock the slot containing the high-value stat.
  5. Tune remaining slots: Spend specialized materials to reroll the remaining open slots until you hit complementary heroic or legendary secondary stats.
