For the complete loadout, see Best Fox (Kitsune) Build 2026 for recommended weapons, tomes, items, and upgrade priorities.
The Best Starting Character for Beginners
Community tier rankings vary; Fox ranges from B to C tier across different tier lists
đ RNG Blessing: Current Luck Scaling
+1.5% Luck per level with no cap. This improves reward quality throughout your run. The current value comes from the V1.0.49 Christmas Patch, which reduced the passive from +2% to +1.5%.
Character Statistics
Complete Stats: 100 HP | 0 Armor | 0 Shield | 1.0 Move Speed | Standard Jump, Evasion, and Pickup Range. Note: Exact secondary stat values and base Luck modifier is sourced from current code-analysis documentation; official detailed stat tables have not been published.
Strengths & Weaknesses
â Strengths
- Available immediately (default character)
- +1.5% Luck per level scales infinitely (current patch)
- +15% base Luck modifier plus uncapped passive growth
- Firestaff has excellent range and AoE
- Perfect for learning game mechanics
- Better loot makes runs more forgiving
- Ranged playstyle allows safe positioning
â Weaknesses
- B-C tier in competitive rankings
- Luck provides indirect power scaling
- Outclassed by S-tier characters in late game
- 100 HP is fragile without defense items
- Firestaff requires good positioning
- Power peaks later than direct combat passives
- Not optimal for speedruns or leaderboards
Starting Weapon: Firestaff
Fox starts with Firestaff, a ranged weapon that shoots exploding fireballs dealing area-of-effect damage on impact.
đ¯ Firestaff Details
- Base Damage: Approximately 10 (community estimate; official base damage tables not published)
- Range: Long-range projectile with explosion radius
- Upgrade Options: Damage, Projectile Count, Projectile Speed, Size
- Type: Fire-based ranged weapon with AoE explosions
Firestaff is beginner-friendly with reliable damage, good range, and AoE explosions. It synergizes well with Quantity Tome (projectile multiplication), Size Tome (explosion radius), and fire damage items such as Spicy Meatballs and Dragonfire.
How Fox's RNG Blessing Works
Current passive: +1.5% Luck per level
Fox gains +1.5% Luck for each character level, with no passive cap stated in the current patch notes. The passive was raised from 1% to 2% in v1.0.17, then adjusted to 1.5% in v1.0.49. This is reward-quality scaling, not Crit Chance or item proc chance.
Passive contribution examples: 10 levels add 15% Luck, 50 levels add 75%, and 100 levels add 150%, before Clover, Luck Tome, Green Credit Card, shrine, pot, or other run bonuses.

Fox Strategy Guide
Early Game (0-10 minutes)
đĄ Early Game Priorities
- Upgrade Firestaff first: Reach Level 4 to 6 before adding additional weapons
- Take XP Tome immediately: Accelerates Luck buildup (+7% per level, v1.0.12+)
- Acquire Luck Tome next: Adds another major Luck source alongside the passive
- Collect all XP crystals: Every level now provides +1.5% Luck (current patch)
- Save gold: Remember that Shady Guy inventory is rolled when you enter the stage
- Practice positioning: Medium to long range is optimal for survivability
- Find Clover as soon as possible: +10% Luck, highest priority item
đ At Level 10 (+15% from the passive)
The passive has begun shifting rarity odds, but individual rolls can still be Common. Use the Luck stat guide for probability examples.
Mid Game (10-20 minutes)
đĄ Mid Game Strategy
- Add 2 to 3 more weapons: Lightning Staff, Aura, or Bow work particularly well
- Take Quantity Tome: Provides significant projectile and coverage boosts for ranged weapons
- Acquire Credit Card (Green): Provides +2% Luck per chest opened for the current run; each card also raises chest prices
- Begin spending gold: New Luck gained inside the stage does not reroll the current Shady Guy inventory
- Visit shrines: Permanent stat boosts compound over the run
- Stack damage items: Joe's Dagger, Big Bonk, Demonic Soul
- Consider Cursed Tome: More enemies equals more XP equals faster leveling
đ At Level 30 (+45% from the passive)
Fox has accumulated a meaningful Luck contribution, but rarity still uses a weighted random roll with diminishing returns.
Late Game (20+ minutes)
đĄ Late Game Optimization
- Target 100%+ total Luck: Around Level 67 before other Luck bonuses
- Maximize weapon upgrades: Push priority weapons to highest available rarity
- Stack survivability items: Chonkplate, Holy Book, Mirror are essential
- Utilize Shrine of Succ: XP-absorbing shrine for rapid leveling
- Open every chest: High Luck makes all loot valuable
- Prepare for Final Swarm: Endless waves spawn after missing the teleporter at 20 minutes
- Acquire Sucky Magnet: Game-changing pickup radius increase (unlock by completing all Charge Shrines in one map)
đ High Luck still uses weighted rolls
Even very high Luck does not guarantee Legendary rewards. Treat it as better average reward quality, not a threshold that removes Common, Rare, or Epic results.
Recommended Weapons for Fox
These weapons synergize well with Fox's ranged, luck-focused playstyle:
⥠Lightning Staff (Available from start) - S-Tier
Chain lightning that automatically jumps between enemies. Perfect 360° coverage. Scales with Size Tome for massive chain radius. Frequently ranked as one of the best weapons in the game.
đ Aura (Unlock: avoid damage for 2 minutes)
360° passive damage circle. Only uses Damage and Size stats, meaning more frequent damage upgrades. Perfect protection for ranged playstyle.
đĄī¸ Aegis (Unlock: block 500 damage as Sir Oofie)
Blocks attacks and sends counter shockwaves. Compensates for Fox's fragility. Effective even at low upgrade levels.
đš Bow (Available from start) - A-Tier
Piercing arrows with critical hit scaling. Critical hit benefits from Luck through better shrine rewards. Good ranged coverage matching Fox's playstyle.
đĢ Revolver (Unlock: 7,500 total kills) - A-Tier
Critical-hit-focused bullets. Upgradeable Critical Chance and Critical Damage stats. Luck improves critical item quality. Pairs with Bow and Sniper for Full Critical builds.
đ Dragon's Breath (FOX UNLOCK: Kill 1,000 Wisps on Desert as Fox) - B-Tier
Fire damage-over-time weapon with Fox-specific unlock requirement. Burning damage synergizes with Firestaff. Combines with Spicy Meatballs for explosive effects.
Other strong options: Blood Magic (sustain heals), Space Noodle (more effective against bosses), Poison Flask (toxic DoT), Frostwalker (freeze crowd control), Sniper (high base damage), Shotgun (spread damage), Bananarang (returning projectile).
Tomes & Items Explained
What are Tomes?
Tomes are passive stat upgrades chosen during level-ups and stack throughout a run. You start with 2 Tome slots. Complete 35 quests to unlock the third Tome slot and 55 quests to unlock the fourth. Weapon slots follow separate milestones: 25 quests for the third slot and 45 for the fourth.
Essential Tomes for Fox:
- XP Tome: Provides +7% XP gain per level (adjusted from +9% in v1.0.12). Accelerates leveling equals faster Luck buildup. Highest priority.
- Luck Tome: Provides +8% Luck per level. Combines with Fox's passive. Second priority.
- Quantity Tome: Provides significant projectile and coverage boosts for most ranged weapons. Game-changing screen coverage improvement.
- Damage Tome: Multiplicative damage boost for all weapons.
- Cooldown Tome: Reduces all weapon cooldowns for increased attack frequency.
- Size Tome: Increases area-of-effect radius for Firestaff explosions, Aura, Lightning chains.
- Cursed Tome: Spawns more enemies for increased XP gain. Use in Holy Trinity build.
Essential Items for Fox:
- Clover (Common, Green): +10% Luck. Highest priority item. Acquire immediately.
- Credit Card (Green) (Common, Green): +2% Luck per chest opened for the current run; each card also raises chest prices by 10%.

Fox Tier Ranking & Meta Position
Fox is rated B-tier to C-tier in competitive Megabonk rankings, with variation across different community tier lists. While excellent for beginners, Fox is outclassed by specialized characters in endgame optimization.
đ¯ Why B-C Tier?
- Indirect scaling: Luck does not provide immediate combat power like critical hit or damage passives
- Outclassed specialists: CL4NK, Dicehead, Robinette dominate competitive play
- Firestaff is B-tier: Reliable but not meta-defining
- Power peaks late: Needs 20+ levels to feel Luck advantage
- Not speedrun viable: Other characters clear content faster
đĄ Why Still Play Fox?
- Best beginner character: Forgiving due to improved loot quality; teaches game mechanics
- Immediately available: No unlock grind required
- Fun loot farming: High Luck makes every run feel rewarding
- Completes all content: B-tier does not mean ineffective, just not optimal
- Unique playstyle: Only character with passive Luck scaling
- Great for learning: Forces understanding of item quality and synergies
S-tier characters that outperform Fox: CL4NK (critical scaling), Dicehead (critical-focused), Robinette (Bow plus gold scaling), Calcium (speed scaling), Monke (survivability).
Community consensus: Fox is a serviceable starter character but an outclassed specialist. Fox serves as training wheels for new players and a fun loot-farming character for casual play, but is not competitive for leaderboards or speedruns.
Common Mistakes to Avoid
â Spending Gold Too Early
Problem: Purchasing items when Luck is low (Level 1 to 15) may waste gold on mediocre loot.
Solution: Check Shady Guy after entering a stage. That stage's inventory was already rolled using your Luck at entry, so waiting and gaining more Luck will not reroll it.
â Neglecting XP Tome
Problem: Slow leveling equals slow Luck buildup equals wasted passive potential.
Solution: Take XP Tome immediately. Every level matters for Fox's power curve. Current value is +7% XP per level (v1.0.12+).
â Not Stacking Luck Items
Problem: Skipping Clover, Credit Card, or Luck Tome wastes Fox's unique advantage.
Solution: Use Luck sources when the build can spare them, but remember the rarity formula has diminishing returns and Luck provides no immediate combat damage.
â Poor Positioning
Problem: Getting too close with 100 HP and no armor results in rapid death.
Solution: Maintain medium to long range. Leverage Firestaff's range to maintain safe positioning.
â Ignoring Final Swarm Preparation
Problem: Not having survivability items when endless waves spawn after missing the teleporter at 20 minutes.
Solution: Acquire Chonkplate, Holy Book, or Mirror before 20 minutes. Endless red ghost waves are extremely deadly.
