Brown Dust2 Gear Refinement: S-Rank Stats & Lowest Diamonds
Brown Dust2 gear refinement relies on sub-stat lock stones to secure high-tier stats, demanding heavy diamond investments. The Gear Option Refining System (added August 2023) uses weighted letter grades (C to S) to determine gear scores up to 24. To minimize costs, calculate diamond-to-stone efficiency, leverage bulk dismantling, and secure premium currency at the lowest prices.

Optimizing equipment across grades (N to UR) and tiers (I to EX) requires precise resource management. Your goal? Maximize Gear Score from 6 (CCC) to 24 (SSS). The difference between an A-rank and S-rank sub-stat dictates battle outcomes. Sub-stat lock stones protect your best rolls while you reroll. Because diamond costs scale rapidly, securing currency efficiently is paramount. For the brown dust 2 lowest diamond gear refinement, players turn to buffget to maximize purchasing power and lock crucial S-rank stats.
Understanding Brown Dust2 Gear Refinement
Equipment Upgrades & Sub-Stats
Brown Dust2 features five gear slots: Weapon, Armor, Helmet, Accessory, and Gloves. Gear falls under grades (N, R, SR, UR) and tiers (I, II, III, IV, EX). Crafting tier distribution relies on strict RNG:
- Tier I: 50%
- Tier II: 30%
- Tier III: 15%
- Tier IV: 5%
Max upgrade level is +9. Sub-stat slots unlock at +3, +6, and +9. The Gear Option Refining System (added August 2-3, 2023) lets you reroll these unlocked sub-stats.
Sub-stats dictate viability. The refinement system assigns values: C=1, B=2, A=3, S=4. Total Gear Score = letter value × position weight (Slot 1: ×1, Slot 2: ×2, Slot 3: ×3).
- Example: S-rank in slot 3 = 12 points (4 × 3). C-rank in slot 3 = 3 points.
Securing S-rank stats in later positions is exponentially more valuable.
Exclusive Sub-Stat Lock Stones
Exclusive (EX) Gear has 1 gold star, inheriting Tier IV base stats plus one powerful exclusive stat. EX gear is restricted to 3-4★ characters (one piece per character).
- Normal lock stones: Protect standard sub-stats.
- Exclusive lock stones: Safeguard EX gear's exclusive stat. Rarer and more valuable.
When to use: The refinement RNG is brutal. Probabilities:
- UR +3: C 45%, B 49%, A 5%, S 1%
- UR +9: C 48%, B 49%, A 2.5%, S 0.5%
- SR +9: C 48%, B 49%, A 2.4%, S 0.6%
Pro tip: Never risk losing an S-rank roll on UR or EX gear. If you land an S-rank exclusive or high-weight sub-stat, apply an Exclusive Sub-Stat Lock Stone immediately.
Lowest Diamond Prices Explained
Buying lock stones from the in-game Pack Shop demands heavy diamond investment, with exclusive lock stones at a premium. Standard pack pricing obscures the actual diamond-to-stone conversion rate. Relying solely on standard shop purchases drains reserves fast.
To optimize diamond-to-stone efficiency, track discount diamonds through packs and external top-ups. When you buy brown dust 2 diamonds sub stat lock resources via buffget, you secure more premium currency for the same cost, lowering the diamond price per lock stone. This efficiency is crucial for chasing sub-1% S-rank probabilities. More attempts = higher mathematical chances of perfect rolls.
Step-by-Step Gear Refinement
Preparing Resources:
- Farm Refining Powder: Daily quests and gear dismantling.
- Obtain Refining Stones: Dismantle N and R grade gears only.
- Acquire Refining Crystals: Dismantle SR and UR grade gears.
- Bulk Dismantle: Use inventory bulk dismantle to convert unused gear into powder.
- Optimize Dismantle Levels: Dismantling before +7 is inefficient for powder yields. Always upgrade to at least +7 first.
Executing Refinement:
- Unlock Options: Upgrade target gear to +9 (requires at least one unlocked option).
- Select Sub-Stat: Choose the stat to reroll.
- Apply Lock Stones: Use Normal or Exclusive stones to protect A/S-rank stats.
- Initiate Refinement: Spend powder, stones, or crystals.
- Evaluate Roll: Check against probability tables. Repeat if not an upgrade.
Common Misconceptions
Misconception: Free Stones Are Enough Free stones from events/dailies are extremely limited and will bottleneck endgame progression. High-end upgrade success rates are brutal:
- UR +8: 2% (UR★5 exclusive +8: 2%)
- SR +8: 5% (SR★5 exclusive +8: 5%)
- R +8: 9% (R★5 exclusive +8: 9%)
- N +8: 15%
You'll burn through free stones instantly. Investing diamonds into lock stones is mandatory.
Misconception: All Sub-Stats Are Equal Due to position weight multipliers, an S-rank in slot 1 (4 points) is worth far less than an S-rank in slot 3 (12 points). Prioritize locking high-value stats in the ×3 position.
And stat priority must align with meta builds. A useless S-rank stat (e.g., excess crit rate on a healer) is worse than a beneficial B-rank (HP% or Defense). Lock based on priority and weight, not just the letter.
Practical Optimization Examples
DPS Gear (Justina, Luvia) Offensive stats in Weapon and Gloves are paramount. Roll an S-rank Attack stat in slot 3 (×3 weight) on a UR Weapon? Use an Exclusive Sub-Stat Lock Stone immediately. That 12-point stat carries your Gear Score. Rerolling other slots is fine, but attempting perfect optimization on all three without lock stones is a fool's errand given the 0.5% UR +9 S-rank probability.
Tank and Healer Gear Prioritize survival stats in Armor, Helmet, and Accessory. Securing an S-rank Defense or HP stat in slot 2 (×2) or 3 (×3) provides massive survivability spikes. With UR upgrade +8 at only 2%, protecting your investment with lock stones after a high upgrade is critical. Don't risk a vital defensive sub-stat for a minor optimization.
Evaluating Your Diamond Investment
Tracking Improvement Measure investment by tracking PvP and high-level PvE performance. Successful refinement means surviving an extra PvP hit or clearing a PvE wave faster. If Gear Score increases but performance stagnates, you locked the wrong sub-stats.
Cost vs. Performance Ratio Calculate gold and diamond cost per Gear Score point gained. Moving from B-rank to A-rank in the ×3 position costs fewer lock stones on average than chasing S-rank (2.5% vs 0.5% probability on UR +9). In practice, settling for A-rank in a heavily weighted slot often offers a better cost-to-performance ratio than infinite S-rank rerolls. Know when to stop and move to the next piece.
Pro Tips for Saving Diamonds
- Timing Purchases: Wait for monthly pack refreshes and special events offering discount diamonds or bonus lock stones. Avoid panic-spending; save for bulk sessions to mitigate RNG variance.
- Maximizing Monthly Pack Value: Monthly packs offer the best diamond-to-cost ratio. Combine them with efficient material farming (dismantling SR/UR gear for crystals instead of buying materials).
- Upgrade First: Always ensure gear is +9 before attempting refinement. Wasting diamonds on lock stones for gear without unlocked slots is a common beginner trap.
