5 Subclasses Explained
1. Arcanist
Rating: A | Difficulty: ★★☆
A pure magical damage build centered on Mana Orbs and Mana Burst. Rapidly accumulates mana to trigger bursts frequently for sustained high damage.
Unlock Condition: Acquire multiple Mana Orbs and equip Mana Staff-type items
Strengths: Consistent high damage through frequent Mana Bursts; intuitive and straightforward Weaknesses: Build falls apart if Mana Orbs don't appear in the shop
2. Chess Master
Rating: A | Difficulty: ★★★
An advanced build that assembles Chess pieces (Pawn, Knight, Bishop, Rook, Queen) to maximize Chess Board synergies. The more pieces in play, the more powerful the buffs.
Unlock Condition: Acquire Chess Board and collect multiple Chess piece types
Strengths: Full set assembled is among the highest combat power of any build in the game Weaknesses: Weak without the pieces; extremely shop-dependent
3. Sword Mage
Rating: B | Difficulty: ★★☆
A hybrid melee-magic build combining weapons like Katana and Harold with magical items. Deals damage on multiple vectors by combining physical attacks with magical buffs.
Unlock Condition: Acquire specific melee weapons like Katana or Harold

Rating: A | Difficulty: ★★☆
A synergy-focused build that attaches gems (Ruby, Sapphire, Emerald, Diamond) to staves, activating unique effects for each gem type.
Unlock Condition: Acquire multiple gem item types
Strengths: Diverse effects based on gem combinations; adaptable to available items Weaknesses: Which gem types appear in the shop is a luck-dependent factor

Build Guides
Build 1: Cupcake Staff Build
Concept: Combine Cupcake with Staff to raise HP and attack speed simultaneously. A simple, stable introductory Mage build.
Key Items
| Item | Role |
|---|---|
| Mana Staff | Main weapon; triggers Mana Burst as mana accumulates |
| Cupcake | Recovers HP and boosts attack speed on activation |
| Mana Orb | Core item that accelerates mana accumulation |
| Potion Belt | Manages stamina to maintain high staff activation frequency |
| Armor Vest | Defensive foundation; sustains HP while waiting for staff activations |

[ Mana Staff ][ Mana Orb ][ Cupcake ]
[ Mana Orb ][ Potion Belt ][ Cupcake ]
[ Armor Vest ][ Lucky Piggy ][ Gem item ]
Build 2: Chess Build (Chess Piece Synergy)
Concept: Assemble Chess pieces in both variety and quantity to maximize Chess Board synergies. With a full set, this is the highest burst potential of any build in the game.
Key Items
| Item | Role |
|---|---|
| Chess Board | Core of all Chess piece buffs; mandatory |
| White Pawn × 2 | Basic piece; synergy improves with 2 copies |
| Black Pawn × 2 | Basic piece; 4 combined pawns triggers further enhancement |
| Knight | Mid-tier piece; boosts attack power and critical rate |
| Bishop | Adds magical attacks and area effects |
| Rook | Rear-support piece; enhances defense and stamina |
| Queen | Strongest piece; amplifies synergies across all other pieces |
| Mana Orb | Accelerates mana accumulation for the Chess Board |
Early Game Plan
- Buy Chess Board as the absolute first priority (the most important item in the game)
- Secure 2 White Pawns and 2 Black Pawns to activate initial synergies
- Add Knight and Bishop in that order for higher-rarity pieces
- Grab Queen immediately if it appears — synergy amplification skyrockets
Chess Board Synergy Reference
| Piece Count | Bonus |
|---|---|
| 4+ pieces | Attack speed +20% |
| 6+ pieces | All piece damage +30% |
| 8+ pieces | Critical rate +25% + Mana Burst enhanced |
| Add Queen | All synergy effects ×2 |
Build 3: Katana Harold Build
Concept: Combine Katana and Harold for a melee-magic hybrid build. Harold's buff raises Katana's activation speed to achieve high-frequency attacks.
Key Items
| Item | Role |
|---|---|
| Katana | High-speed melee main weapon |
| Harold | Support weapon that enhances Katana's damage and activation speed |
| Mana Orb | Appends Mana Burst to Katana activations via mana accumulation |
| Speed Ring | Further increases attack speed |
| Armor Vest | Essential defense item for melee builds |
| Potion Belt | Stamina management |
Strategy Notes
- Place Harold adjacent to Katana to maximize the activation speed buff
- Position Mana Orbs near Katana to accelerate mana accumulation
- Melee builds take more hits — secure 2+ armor slots
Build 4: Rainbow Potion Staff Build
Concept: Gain powerful random buffs from Rainbow Potion while dealing high damage with staves. High luck-dependency, but explosive upside.
Key Items
| Item | Role |
|---|---|
| Rainbow Potion | Key item granting random powerful buffs |

| Mana Orb × 2 | Maximizes mana accumulation for frequent bursts |
| Potion Belt | Manages potions and replenishes stamina |
| Lucky Ring | Enhances Rainbow Potion effects |
| Armor Vest | Defensive foundation |
Strategy Notes
- Multiple Rainbow Potions stack layered random buffs each round for exceptional power
- Place Mana Orbs adjacent to the Staff to speed up mana accumulation
- When buffs line up the build is overwhelming, but stack armor as insurance for suboptimal rolls

|---|---|
| Shiny Mantle | Buffs all gem items currently equipped |

Early Game Plan
- Secure Shiny Mantle as top priority
- Gem items improve synergy as variety increases — aim for 2–3 types minimum
- Combine with Mana Staff to convert gem synergies into damage
- Buy Gem Pouch or Gem Bag immediately if they appear to amplify synergies
Gem Effects Reference
| Gem | Key Effects |
|---|---|
| Ruby | Attack power +, fire damage added |
| Sapphire | Mana accumulation speed +, cold damage added |

Gameplay Tips
Early Game (Rounds 1–5)
- Secure Mana Orbs as first priority: All Mage builds depend on Mana Orbs for damage; without them, output suffers
- If going Chess build: buy Chess Board immediately: It's expensive but early acquisition is critical
- Use Puzzle Bag to maximize space efficiency: Leverage the bag's shape to pack in more items
- Collect 4+ Pawns to trigger Chess Board synergy: The synergy threshold unlocks at 4 pieces
Shop Priority by Round
| Rounds | Top Priorities |
|---|---|
| 1–3 | Mana Orbs (multiple), Chess Board (if Chess build) |
| 4–7 | Various Chess pieces (4+ Pawns), Shiny Mantle |
| 8–12 | Knight, Bishop, Rook; gem items |
| 13+ | Queen, Mage Hat, defense upgrades |
Backpack Placement Tips
- Chess Board at the center of the backpack: Place Chess pieces around it to maximize synergy coverage
- Mana Orbs directly adjacent to staves: Achieve the fastest possible mana accumulation
- Gems in contact with Shiny Mantle: Ensure synergy effects activate reliably
- Use the Puzzle Bag's bag system: Place bags inside bags to expand storage capacity
Mage Weaknesses and Counters
Weakness 1: Weak Early Game
- Problem: Extremely fragile before assembling Chess pieces. Early rounds are very difficult to win
- Counter: Rely on Mana Orb bursts to survive early game. Use Cupcake healing to bridge to mid-game
Weakness 2: High Shop Dependency
- Problem: Win rate fluctuates dramatically based on whether Chess pieces, gems, or rare items appear
- Counter: Maintain flexibility to pivot to Katana Harold or Potion builds when Chess pieces don't appear
Weakness 3: Vulnerable to Reaper Poison
- Problem: Staff activations are slow, allowing poison stacks to accumulate
- Counter: Include Life Staff in the backpack for regular debuff cleansing. Increase Mana Orb count for more frequent bursts to win early
Weakness 4: Difficult Backpack Management
- Problem: Chess pieces, gems, Mana Orbs, and staves all compete for limited slots
- Counter: Use the Puzzle Bag system to optimize space. Sell items proactively once their role is fulfilled to make room for core items
Summary
The Mage demands the most investment of any class, but rewards mastery with unrivaled potential.
- Most accessible for newcomers: Cupcake Staff Build (Mana Burst + healing)
- For synergy explosion fun: Chess Build (full set with Queen is the strongest)
- For a unique playstyle: Shiny Mantle Gem Build (gem combinations)
- For melee + magic hybrid: Katana Harold Build
Start with the Cupcake Staff Build to learn the Mage fundamentals (Mana Orb management, staff placement). Once comfortable, tackle the Chess Build's complex synergy system for the full Mage experience.
