Choosing wrong at the end of a Dungeon Lootr boss fight costs you a full run. After every boss, three Dungeon Lootr boss reward chests appear and you can only open two before extracting. Smart players treat the three-chest decision like a build-defining moment, because the picks feed straight into class evolution and your next Boss Rush payout. This guide breaks down how the rewards roll, which chest biases match your class, and how to time your pulls for the best Boss Rush class item drops.
How the Three-Chest System Works After Every Boss
Every dungeon in Dungeon Lootr ends with a multi-HP-bar boss fight. Once the boss dies, three glowing chests spawn on the extraction platform, each representing a different reward pool. You pick two of three, then extract to the lobby where you can forge, reforge, or reroll your class. The chest you skip is destroyed when the run ends, so every boss fight forces a real trade-off.
Reward Pool Breakdown
The three pools are not cosmetic variants of each other. They pull from distinct drop tables with weighted probabilities, so a Chest A run in Boss Rush feeds class evolution recipes like EX catalysts and fragment sets, while Chest B rolls Forge Stones and Reforge Stones for build crafting, and Chest C biases toward Luck Potions and Coin stacks — meaning the chest you pick at the end of every boss rush directly determines whether your run pushes your build forward or stalls it.
| Chest | Primary Pool | Secondary Pool | Best Use Case |
|---|---|---|---|
| Chest A — Class Item | Class-specific fragments, evolution tokens, EX-class catalysts | Stat scrolls tied to class identity | Players chasing Awakened Devil EX or Awakened Vergil |
| Chest B — Rare Materials | Boss-specific crafting mats, Forge Stones, Reforge Stones | Aspect Gems | Players building a new class or reforging stats |
| Chest C — Consumables & Coins | Luck Potions, Aspect Gems, Coin stacks | Random gear pieces | Early-game players building currency reserves |
The Class Item chest is the single most important pull for anyone running Boss Rush, because it directly feeds the evolution recipes that turn base classes into their EX variants. According to the official Dungeon Lootr page on Roblox, evolution materials cannot be purchased and must drop from bosses or chests, which is why the three-chest choice carries real weight.
Why You Only Get Two Picks
The two-of-three limit exists to keep players grinding. Community testing on Boss Rush runs shows that a player who consistently opens both the Class Item and Rare Materials chests averages one evolution catalyst every 8-10 bosses, while a player who skips the Class Item chest often goes 20+ bosses without a single evolution token. The Consumables chest is the typical sacrifice slot for veterans, but newer players should weigh it carefully because Luck Potions and Aspect Gems accelerate early gear upgrades.
Boss Rush Rewards: Why the Three-Chest Loop Matters More
Boss Rush is a 100-floor escalating gauntlet that resets every time you extract. According to community data from the Lunmei release trailer on YouTube, a skilled solo player clears the full gauntlet in under 15 minutes with a top-tier class, which means you will face roughly 100 three-chest decisions per run. That volume turns the two-of-three choice into the most important decision point in the entire game mode.
Boss Rush Reward Density by Floor Bracket
The reward density shifts as you climb. Early floors shower you with consumables and common materials, while late floors concentrate class item drops into a smaller window of chests. Knowing where the density peaks lets you plan which two chests to favor as your run progresses.
| Floor Bracket | Chest A — Class Item Rate | Chest B — Rare Materials Rate | Chest C — Consumables Rate |
|---|---|---|---|
| Floors 1-25 | Low | Medium | High |
| Floors 26-50 | Medium | Medium | Medium |
| Floors 51-75 | High | High | Low |
| Floors 76-100 | Very High | High | Low |
The data shows that floors 51-100 are where the best Boss Rush class item drops concentrate, so many experienced players skip the Consumables chest on every boss from floor 50 onward to maximize evolution material intake. If you are still building a coin reserve or chasing Aspect Gems for reforging, the Materials chest is your second pick on early floors and the Class Item chest takes priority once you cross the halfway mark.
Average Boss Rush Time and Pick Budget
Your Boss Rush time budget directly affects how many chest decisions you face across the 100-floor sprint, since each floor awards one of three chests and slower clears mean more exposure to RNG-heavy Material drops. The table below uses community-reported average clear times for top-tier classes from the ClickBytes Discord, where the ~100 chest estimate assumes near-100% room completion rates typical of optimized S-Tier and A-Tier Awakened Devil EX runs; B-Tier and below often see 80-90 chests due to skipped Mob Rooms and Elite Rooms, shifting the loot economy noticeably.
| Class Tier | Average Full Clear (100 floors) | Approx. Chests Faced | Recommended Pick Bias |
|---|---|---|---|
| S-Tier (Awakened Devil EX, Honored One) | 12-14 min | ~100 | Class Item + Materials |
| A-Tier (Cursed King, Anti Magic) | 15-18 min | ~100 | Class Item + Materials |
| B-Tier (base Devil, Vergil pre-evo) | 19-23 min | ~100 | Materials + Consumables |
| C-Tier and below | 25+ min or wipe | ~100 | Class Item + Consumables |
If you are running a B-Tier class, the Rare Materials chest takes priority over the Class Item chest because you need Forge Stones and Reforge Stones to keep your stats competitive. Without those upgrades, even the right class items will not push you into the A-Tier clear-time window where the real Boss Rush rewards become consistent.
Best Boss Rush Class and How Chest Picks Change Per Class
The best Boss Rush class is whichever class matches your chest pick strategy, because the wrong picks feed the wrong evolution tree. Community testing consistently ranks Awakened Devil EX at the top of Boss Rush tier lists, but the class requires a very specific chest strategy to evolve from base Devil into its EX form.
Top Boss Rush Classes and Their Chest Preferences
| Class | Tier | Primary Evolution Material | Chest A Priority | Chest B Priority | Chest C Skip? |
|---|---|---|---|---|---|
| Awakened Devil EX | S | Devil Catalyst + Boss Coins | Always | Often | Yes |
| Honored One | S | Honored Fragment + Aspect Gems | Always | Sometimes | Yes |
| Cursed King | A | Cursed Mark + Reforge Stones | Often | Always | Yes |
| Anti Magic | A | Anti Magic Seal + Forge Stones | Often | Always | Yes |
| Awakened Vergil | A | Vergil Blade Shard + Luck Potions | Always | Sometimes | No (needs potions) |
| Base Devil | B | Devil Catalyst | Always | Rarely | No (needs coins) |
The data shows a clear pattern: the best Boss Rush class for your run depends on whether you can commit both chest picks to its evolution path. If you spread picks across multiple classes, you dilute your material intake and slow every evolution by a factor of two or three. A focused two-chest strategy on a single class is almost always faster than a scattered three-class approach.
Building Around Your Best Class for Boss Rush
If you already own a base-tier version of one of the S or A classes, your chest strategy should funnel 100 percent of your class item picks into that class's evolution tree. The Dungeon Lootr class tier list confirms that Awakened Devil EX and Honored One dominate the Boss Rush leaderboards, but only because players commit both chest picks to their evolution materials for dozens of consecutive runs.
Players who swap classes every few runs end up with fragments for five different classes and zero completed evolutions. If you are chasing a specific EX-class, treat the Class Item chest as mandatory and let the second pick float between Rare Materials and Consumables based on your current Forge Stone and Luck Potion reserves.
Timing Your Picks for Maximum Boss Rush Payouts
The Boss Rush mode scores your run based on clear time, floors cleared, and total reward value. Picking the right two chests at the right floor matters because the reward value of each chest tier scales with floor number. A Class Item chest on floor 90 is worth roughly 4-5x the same chest on floor 10, based on community-reported drop rates.
Floor-Based Pick Priority Cheat Sheet
| Run Phase | Primary Pick | Secondary Pick | Skip |
|---|---|---|---|
| Floors 1-20 (warmup) | Rare Materials | Consumables | Class Item (low drop rate) |
| Floors 21-50 (build) | Class Item | Rare Materials | Consumables |
| Floors 51-80 (push) | Class Item | Rare Materials | Consumables |
| Floors 81-100 (climax) | Class Item | Class Item (if rerolled) | Rare Materials or Consumables |
The climax floors are where you should consider a double-Class-Item pull if the chest generation happens to roll two Class Item variants, because the drop rate multiplier on those floors makes it the highest expected value per pick. This only applies when you already have a healthy stockpile of Forge Stones and Reforge Stones from earlier floors, so do not skip the Materials chest during the build phase if your stockpile is empty.
Boss Rush Time Targets and Reward Tiers
Your clear time does more than just shift the reward tier — it also stacks multiplicatively on top of every class item drop and three-chest bonus you secured during the run, so a sub-12-minute S-Tier clear can effectively double the value of mid-floor chest picks compared to a sloppy 18-minute B-Tier clear that picked the same chests.
| Clear Time | Reward Tier | Bonus |
|---|---|---|
| Under 12 min | S-Tier clear | +50% Boss Rush rewards, exclusive cosmetics |
| 12-15 min | A-Tier clear | +25% Boss Rush rewards |
| 15-20 min | B-Tier clear | Base Boss Rush rewards |
| 20+ min or wipe | No bonus | Base rewards only |
The fastest clear times require an S-Tier class, which requires a focused chest strategy, which requires understanding the three-chest system. Every layer feeds the next, and the players who hit the under-12-minute S-Tier bonus are almost always the ones who committed to a single-class evolution path from their very first Boss Rush run.

Gear Synergy and Chest Picks for Early-Game Players
Early-game players often lack the class variety to commit fully to a single evolution path, so the chest strategy shifts toward building a flexible foundation. If you are still unlocking classes and experimenting with builds, the three-chest decision should prioritize gear upgrades and currency over class-specific evolution materials.
Early-Game Chest Priority Matrix
| Player Goal | Chest A | Chest B | Chest C |
|---|---|---|---|
| Unlock a new class fast | Skip | Always | Sometimes |
| Build a starter class | Rarely | Always | Always |
| Save coins for Lucky Spins | Skip | Rarely | Always |
| Stockpile Forge Stones | Skip | Always | Sometimes |
Early-game players chasing the best gear for early damage and defense should treat the Rare Materials chest as their primary pick, because Forge Stones and Reforge Stones are the bottleneck for upgrading any starter weapon. Aspect Gems from the Consumables chest are equally important for stat optimization, but only once you have a weapon worth reforging.
The Class Item chest becomes a priority once you have committed to a specific class and started chasing its evolution. Until then, spreading your picks across gear materials and consumables gives you a stronger foundation for every later Boss Rush attempt.
Frequently Asked Questions
What is the best chest to pick in Dungeon Lootr boss reward chests for new players?
New players should prioritize the Rare Materials chest and the Consumables chest on every boss, because Forge Stones, Reforge Stones, Aspect Gems, and Luck Potions fuel gear upgrades that make every class viable. The Class Item chest is tempting but most early-game classes do not need evolution materials until you commit to an EX-class path, so skipping it early lets you build a stronger foundation for later Boss Rush runs.
How do the three chests after a Dungeon Lootr boss differ in drop rates?
The Class Item chest has the lowest drop rate on early floors but scales sharply after floor 50 in Boss Rush, while the Rare Materials chest stays consistent across all floors. The Consumables chest has the highest rate on floors 1-25 and drops off after floor 50, which is why veteran players skip it during the climax phase of Boss Rush and focus both picks on Class Item and Rare Materials.
What is the best Boss Rush class for farming dungeon lootr boss rush class item drops?
Awakened Devil EX is the best Boss Rush class for farming class item drops because it clears the full 100-floor gauntlet in roughly 12-14 minutes, which means more bosses faced per hour and more three-chest decisions per session. Honored One is a close second with similar clear times, while Cursed King and Anti Magic sit in the 15-18 minute A-Tier window that still produces solid rewards without hitting the S-Tier bonus.
How long should a good Dungeon Lootr Boss Rush run take?
A good Boss Rush run with an S-Tier class should clear all 100 floors in 12-15 minutes, and an elite run with Awakened Devil EX or Honored One can hit the under-12-minute S-Tier bonus threshold. Players using B-Tier classes should target the 19-23 minute range, which still produces full reward payouts but does not unlock the time-based bonus multiplier.
Can you reroll the three chests after a boss fight in Dungeon Lootr?
No, the three chests are fixed for that boss kill and you cannot reroll them mid-run. Your only control is which two of the three you open, so planning your pick bias before the boss dies is essential. Once you extract, the skipped chest is destroyed and its potential rewards are lost until the next run.
