Chest Drop Guide
Use chest level, source stage, and rates to choose farming targets.
Chests need source, level range, and real drop-rate context.
Quick Take
- 1
Read chests by source, level range, and drop table — all three matter
- 2
No real drop rate = no profit calculation — use source context only
- 3
Tradable drops need BOTH rate and price to calculate value
- 4
Farm chests you can obtain consistently — reliability beats theoretical value
Three Dimensions of Every Chest
Chests are not loot boxes with random contents. Each chest has a defined structure that, when understood, tells you exactly what to expect and what remains unknown.
Read every chest by these three dimensions: 1. Source — What stage, monster, or activity drops this chest? Can you obtain it reliably? 2. Level range — What gear level band does this chest cover? Does it match your current progression? 3. Drop table — What items are possible, and (when data exists) at what rates?
If any of these three layers is missing or unclear, your conclusions about the chest must be conservative.
The Drop Rate Boundary
This is the most important concept on this page. Without real chest → item → dropRate mapping data, we cannot calculate: - Expected items per hour - Market value per clear - Profit per minute
This site's policy: when rates are missing, show data status — do not show invented numbers. You'll see "掉率数据不足" (Drop data unavailable) rather than a random percentage. This protects you from making decisions based on fiction.
When Drop Rates Exist - Compare rates across chests for target items - Multiply by clear time for items-per-hour estimates - Combine with market prices (when available) for profit estimates
When Drop Rates Don't Exist - Use only source and level context - Farm for known drops, not theoretical ones - Don't build a market strategy around unrated chests
Market Link: The Two-Key Lock
Converting chest drops into market income requires two keys: 1. Drop rate — how often the item drops 2. Market price — what the item sells for
Without BOTH, the chest-to-market pipeline cannot produce reliable estimates. A price without a rate cannot be converted to hourly value. A rate without a price cannot be converted to dollar value.
The Profit Calculator's Honesty The profit calculator on this site will refuse to output a market profit number when either key is missing. This is by design. A tool that invents data is worse than no tool at all.
Practical Chest Farming Strategy
Step 1: Find Your Stage Use the stage page (`/stages`) to find a stage you can clear consistently. Check: - Gold per clear - XP per clear - Kill count - Clear time estimate
Step 2: Check the Chests Which chests drop on your chosen stage? Open each chest page and check: - Item list — any items you specifically want? - Level range — does it match your current gear needs? - Drop rates — are they available?
Step 3: Set a Target Before farming, know what you're farming FOR: - **Gold farming** → Optimize gold per minute, chests are bonus - **XP farming** → Optimize XP per minute, chests are bonus - **Item hunting** → Farm the chest with the best chance of your target item - **Market farming** → Only when rates AND prices exist
Step 4: Measure and Adjust After 10-20 runs, check your actual results against expectations. If you're getting fewer drops than expected, try a different stage or chest type.
Chest Types Reference
| Chest Type | Typical Source | Pool Size | Best Use |
|---|---|---|---|
| Normal Monster Box | Regular monsters | Small (3-8 items) | Targeted material/gear farming |
| Stage Boss Box | Stage boss kills | Medium (8-20 items) | Balanced drops, higher rarity |
| Act Boss Box | Act completion | Large (15-40 items) | Rare/high-value items |
| Special/Event Box | Events, achievements | Varies | Unique or event-limited items |
Common Mistakes
Estimating profit from incomplete or missing drop rates
Reading only the chest name without checking source and level
Ignoring clear time when comparing chest farming routes
Assuming 'possible drops' equals 'expected income'
Mixing chest drop value into pure gold/XP farming calculations
FAQ
What if drop rates are missing for a chest
Use only what you know: source stage, level range, and item list. Do not invent rates or estimate profit.
Can chest market value be calculated
Only when both real drop rates AND real market prices exist. Missing either = no calculation.
Which chest should I farm
Farm the chest you can obtain most reliably from a stage you clear consistently. Consistency beats theoretical best drops.
How do I read a chest page
Source stage → level band → item list → drop rates (if available) → market link (if tradable). Missing layers = conservative conclusions only.
What's the difference between chest types
Normal Monster Box (small pool), Stage Boss Box (medium pool), Act Boss Box (large pool, rare items). Each has different farming strategies.
Can I farm multiple chest types at once
Yes, if the same stage drops multiple chest types. Check the stage detail page for its complete chest list.
