Reaper Overview and Strengths

The Reaper is Backpack Battles' sustained damage specialist, built around poison stacking, lifesteal, and the Demonic Flask. Rated B Tier. Rather than raw burst damage, the Reaper excels at relentlessly chipping away at opponents over time. When fully assembled, the build achieves remarkable win consistency — but mastering its mechanics and decision-making makes this an advanced-level class.

Class Rating

Item Details
Tier B Tier
Difficulty ★★☆ (Intermediate to Advanced)
Playstyle Poison stacking, lifesteal, Demonic Flask consumption
Core Strength High survivability through the combination of sustained damage and healing

Class-Exclusive Mechanics

  • Poison: A stacking damage type that drains enemy HP every turn. Built up through Death Scythe and other poison items
  • Lifesteal: Converts a portion of damage dealt into HP recovery. Extremely powerful in prolonged fights
  • Demonic Flask: A consumable item that enhances HP, attack power, and poison damage. The core of the Witch build

Starting Bag Selection

Bag Features Recommendation
Relic Case Amplifies synergies for Tarot Cards and curse-type items; optimal for Witch builds ★★★
Storage Coffin High capacity; suited for power-style builds that pack many items ★★★
Demonic Flask Selecting the Flask itself as a starting bag; the entry point for Potion builds ★★★

Recommendation: If you're new to Reaper, the Storage Coffin is the safest choice for maximum item flexibility.


5 Subclasses Explained

1. Alchemist

Rating: A | Difficulty: ★★☆

A build centered on Demonic Flasks and potion-type items. Efficiently consume and replenish Flasks to continuously escalate your combat power.

Unlock Condition: Acquire multiple Demonic Flasks

Strengths: Combat power increases with every Flask use; gets stronger as the game progresses Weaknesses: Flask depletion causes a sudden drop in power

2. Deathbringer

Rating: A | Difficulty: ★★☆

An attack-focused subclass that aims to equip two or more Death Scythes for a Double Death Scythe build. Rapidly stacks poison to defeat opponents in a short window.

Unlock Condition: Acquire 2 Death Scythes

Strengths: Easy-to-understand poison stacking from early game; aggressive and straightforward Weaknesses: Tends to leave defense thin; less effective against opponents with poison cleanse

3. Hexblade

Rating: B | Difficulty: ★★★

An advanced poison-focused build that combines Tarot Cards with curse-type items to layer debuffs and amplify poison damage.

Unlock Condition: Acquire multiple Tarot Cards

Strengths: Debuff + poison combination is advantageous against many builds Weaknesses: High item dependency; fragile if the build isn't assembled correctly

4. Snake Charmer

Rating: B | Difficulty: ★★☆

A hybrid evasion + poison build built around Snake items. Each Snake activation applies poison while evasion reduces incoming damage.

Unlock Condition: Acquire Snake-type items

Strengths: Chip damage while surviving through evasion Weaknesses: Durability drops if evasion fails to trigger

5. Vampire

Rating: A | Difficulty: ★☆☆

A build that maximizes lifesteal, recovering HP with every attack. The longer the fight lasts, the more advantage the Vampire builds. The most intuitive and accessible Reaper subclass.

Unlock Condition: Acquire multiple lifesteal items

Strengths: Straightforward and stable; dominant in long fights Weaknesses: Vulnerable to burst damage (Pyromancer, high-crit builds)


Build Guides

Build 1: Alchemist Potion Build (Flask-Focused)

Concept: Progressively amplify combat power by consuming Demonic Flasks. A scaling build that gets stronger as the game progresses.

Key Items

Item Role
Demonic Flask Core of the build; each use boosts attack, HP, and poison damage
Potion Belt Manages stamina and multiple potions simultaneously
Curse Potion Flask-type item that applies additional poison
Tarot Card (Death) Applies a powerful debuff to enemies at round start
Armor Vest Provides durability until Flask effects kick in
Skeletal Shield Combines defense with counterattack

Early Game Plan

  1. Secure Demonic Flask as top priority (aim for multiple copies)
  2. Use Potion Belt to stabilize Flask management
  3. Stack early poison with Death Scythes to ensure survival
  4. Plan Flask consumption strategically in mid-game to escalate power step by step

Build 2: Double Death Scythe Build

Concept: Rapidly accumulate poison stacks with two Death Scythes. A simple yet powerful offensive build.

Key Items

Item Role
Death Scythe × 2 Main weapons that apply poison stacks with every hit
Poison Goober Support item that amplifies poison damage
Snake Supplements HP/Luck and poison duration
Tarot (Moon) Applies confusion debuff to enemies, disrupting their activations
Life Staff HP recovery on activation + cleanses 2 debuffs
Armor items Compensates for the defensive weakness of this offensive build

Early Game Plan

  1. Make acquiring 2 Death Scythes the single highest priority from game start
  2. Once both Scythes are secured, add Poison Goober to amplify damage
  3. Acquire Snake to strengthen HP/Luck and extend poison duration
  4. Defense is thin, so always reserve 1–2 slots for armor

Layout Example

[ Death Scythe     ][ Death Scythe    ][ Poison Goober     ]
[ Snake            ][ Tarot (Moon)    ][ Life Staff        ]
[ Armor Vest       ][ Skeletal Shield ][ Potion Belt       ]

Build 3: Hexblade Poison Build (Poison Specialized)

Concept: Break down enemy defenses with Tarot Card debuffs while stacking poison damage. An advanced build for experienced players.

Key Items

Item Role
Various Tarot Cards Apply debuffs to enemies (Death, Moon, Tower, etc.)
Poison Blade Applies high-stack poison with every attack
Poison Goober Multiplies poison damage
Curse Ring Amplifies poison damage further under cursed status
Dark Potion Key item that applies both poison and curse simultaneously
Skeletal Shield Combines defense with poison counterattack

Strategy Notes

  • Think through Tarot Card combinations before purchasing them
  • Simultaneous poison and curse stacking creates multiplicative damage spikes
  • Early game damage is low — stack defense and focus on surviving to mid-game

Build 4: Snake Poison Tank Build (Evasion + Poison)

Concept: Dodge enemy attacks with Snake items while accumulating poison. A defensive attrition build.

Key Items

Item Role
Snake (Cobra, etc.) Main items that apply evasion + poison
Poison Goober Poison damage amplification
Armor Vest Insurance for when evasion fails
Life Staff Sustains long fights with HP recovery + debuff cleanse
Skeletal Shield Counterattack against physical attacks
Tarot (Star) Further increases evasion rate

Strategy Notes

  • Treat evasion as a supplement, not a foundation. Ensure sufficient armor so you can absorb hits when evasion fails
  • Don't rush poison stacks. Prioritize Life Staff HP management first
  • Tarot (Star) raises evasion rate, making it a strong pairing with other Tarot cards

Build 5: Vampiress Lifesteal Build

Concept: Push lifesteal to its maximum so healing output exceeds all incoming damage. The most straightforward and stable Reaper build.

Key Items

Item Role
Bloodscythe Reaper-exclusive high-lifesteal weapon
Vampire Cloak or Ring Significantly boosts lifesteal rate
Life Staff HP recovery on activation + cleanses 2 debuffs
Heal Potion Grants adjacent weapons the lifesteal effect
Armor Vest Defensive base; combined with lifesteal, effectively doubles endurance
Potion Belt Sustains stamina to maintain high activation speed

Early Game Plan

  1. Secure Bloodscythe or Vampire Ring as top priority
  2. Acquire Life Staff for combined HP recovery and debuff cleansing
  3. Place Heal Potion adjacent to weapons to propagate the lifesteal effect
  4. Reserve 1–2 armor slots to prevent one-shot deaths

Build 6: Witch Demonic Build (Demonic Flask Specialized)

Concept: Acquire multiple Demonic Flasks and consume them every round for explosive, escalating combat power. A high-damage build for advanced players.

Key Items

Item Role
Demonic Flask × 2–3 Multiple copies create a consume-and-replenish cycle each round
Witch Hat Amplifies effects when Flasks are consumed
Tarot Card (Judgement) Special Tarot that assists with Flask replenishment
Death Scythe Used in parallel as a poison stack source
Poison Goober Poison damage amplification
Skeletal Shield Combines defense and counterattack

Strategy Notes

  • The Demonic Flask's lifecycle of "consume → replenish → consume" is the build's foundation
  • Two or more Flasks allow alternating consumption to maintain a continuously enhanced state
  • Tarot (Judgement) stabilizes Flask replenishment — always pair them together

Gameplay Tips

Early Game (Rounds 1–5)

  1. Secure Death Scythes first: The Reaper's basic weapon. Stack poison from round one to chip down opponents
  2. Decide subclass direction: Flask-heavy shop → Alchemist; multiple Snakes → Snake Charmer; lifesteal items → Vampire
  3. Always keep at least one armor slot: Reaper builds tend to be offensive, but one armor piece is mandatory
  4. Buy Tarot Cards opportunistically: They pair well with all Reaper builds

Shop Priority by Round

Rounds Top Priorities
1–3 Death Scythes (×2), Tarot Cards
4–7 Subclass core (Demonic Flask or Snake)
8–12 Poison Goober, Life Staff
13+ Witch Hat, Skeletal Shield, defense upgrades

Backpack Placement Tips

  • Death Scythes placed side by side: Two adjacent Scythes trigger synergy, improving poison stack efficiency
  • Tarot Cards next to weapons: Aligning activation timing makes combo debuffs easier to land
  • Flasks accessible for activation: Be mindful of activation order when placing them at round start
  • Snakes adjacent to evasion items: Chain evasion effects together

Reaper Weaknesses and Counters

Weakness 1: Low Early Game Damage

  • Problem: Poison takes time to stack, making early rounds difficult to win
  • Counter: Get 2 Death Scythes to accelerate poison stacking. Add Poison Goober to amplify poison damage from the start

Weakness 2: Pyromancer One-Shot Potential

  • Problem: Reaper's sustained-damage style struggles to handle Pyromancer's high-Heat burst attacks
  • Counter: Stack extra armor to reduce per-hit damage. Use Life Staff's continuous healing to endure the fight

Weakness 3: Ranger Lifebinder Counters Poison

  • Problem: Lifebinder builds cleanse poison debuffs, neutralizing Reaper's main damage type
  • Counter: Maximize poison stack volume to outpace the cleanse rate. Prioritize Double Scythe + Poison Goober to stack as fast as possible

Weakness 4: Backpack Space Pressure

  • Problem: Demonic Flasks, Tarot Cards, and Death Scythes all compete for the same limited slots
  • Counter: Choose Storage Coffin as your starting bag. Sell items aggressively once their role is fulfilled to free up space

Summary

The Reaper is a challenging class that rewards mastery with exceptional stability.

  • Most stable build: Vampiress Lifesteal Build (lifesteal + healing)
  • For aggressive offense: Double Death Scythe Build
  • For late-game explosive power: Witch Demonic Build (multiple Flasks)
  • For advanced challenge: Hexblade Poison Build

Start with the Double Death Scythe build to understand how poison stacking and lifesteal work together. Once you're comfortable with those mechanics, advance to Flask-integrated complex builds for a deeper Reaper experience.
