The Armor Tome is a defensive Tome in Megabonk that increases a character's total Armor. Higher armor reduces the damage taken from enemy hits, making it an essential option for tanky and survival-focused builds. It is not available by default and must be unlocked by fulfilling specific conditions.
Overview
- Stat: Armor (Damage Reduction)
- Base upgrade per level: +12% armor
- How to unlock: Kill 5,000 enemies as Sir Oofie
- Max level: 99
- Category: Defensive Tome
Armor is a percentage-based damage reduction stat that makes you tankier without requiring active play. Unlike shields that regenerate or HP that can be healed, armor provides consistent damage mitigation on every hit.
Armor Scaling
See how damage reduction improves with investment:
+60% Armor
Level ~5
Noticeable tankiness. You're taking measurably less damage from all sources.
Example: 100 damage hit â ~62-75 damage taken (25-38% reduction)
+180% Armor
Level ~15
Significant mitigation. You're significantly more durable and can facetank much more.
Example: 100 damage hit â ~45-60 damage taken (40-55% reduction)
+360% Armor
Level ~30
Heavy armor. You're a tank that can absorb massive punishment.
Example: 100 damage hit â ~30-45 damage taken (55-70% reduction)
+600%+ Armor
Level 50+
Near-invincible. Enemies barely scratch you, allowing aggressive facetank strategies.
Example: 100 damage hit â ~20-35 damage taken (65-80%+ reduction)
How Armor Works
đĄī¸ Armor Mechanics
Damage Reduction: Armor provides percentage-based damage reduction. The exact formula depends on the game's implementation, but generally follows a diminishing returns curve to prevent complete invulnerability.
Damage Taken = Base Damage à (1 - Armor Reduction %)
Common formula: Reduction % = Armor / (Armor + Constant)
Stacking: Armor benefits from diminishing returns - the first 100% armor is more valuable than the second 100%. However, it always provides value and scales infinitely with enemy damage.
Application: Armor reduces ALL incoming damage - projectiles, melee, explosions, and environmental hazards. It's a universal defensive stat.
Effects
- Each level grants +12% Armor
- Damage taken from all sources is reduced proportionally
- Particularly valuable when combined with other forms of sustain such as Regen Tome, Shield Tome, and Bloody Tome
- Scales infinitely - more valuable against high-damage enemies
- Passive benefit requiring no player input
How to Unlock
đĄī¸
Sir Oofie
The tanky knight character. High HP, built-in armor, slower movement. Perfect for unlocking the Armor Tome.
đ Unlock Requirement
Kill 5,000 enemies as Sir Oofie
đĄ Tips for Unlocking
âĸ Play multiple full runs with Sir Oofie to accumulate kills
âĸ Choose high enemy density stages and difficulties
âĸ Use AoE weapons to maximize kill count per run
âĸ Consider using Cursed Tome for even more enemies
âĸ Progress tracked across all runs - it's cumulative

Defense Comparison
đĄī¸ Armor vs Shield vs Health
Three primary defensive stats serve different roles:
đĄī¸ Armor (This Tome)
Damage mitigation
Reduces all incoming damage by %. Passive, always active, no regeneration needed. Best for consistent tanking.
Reduces all incoming damage by %. Passive, always active, no regeneration needed. Best for consistent tanking.
đĄī¸ Shield
Regenerating buffer
Takes damage first, auto-regenerates. Best for active play with dodging. More forgiving of mistakes.

â¤ī¸ Health
Raw capacity
Maximum HP pool. Requires healing to recover. Best for face-tanking. More stable baseline.
Maximum HP pool. Requires healing to recover. Best for face-tanking. More stable baseline.
Best strategy: Combine Armor with HP and Shield for maximum effective health. Armor makes every point of HP and Shield worth more.
Synergies
Armor extends shield life by reducing incoming damage before HP is lost. Multiplicative value.
Taking more hits while being tanky lets you reflect more consistent damage. Armor enables facetank strategies.
Armor slows down damage intake, giving regeneration more time to restore HP. Sustain amplification.
Armor makes every point of lifesteal more effective by reducing how much HP you lose. Healing efficiency boost.
Increased enemy density pairs well with extra durability, allowing you to survive waves that would overwhelm glass-cannon builds.
Armor makes every HP point more valuable. The ultimate tank combo for maximum effective health.
Strategy Guide
- Best suited for defensive or hybrid builds that prioritize survival
- Effective in long boss fights where incoming damage is sustained over time
- Useful for beginners struggling with survivability before mastering dodge mechanics
- Investing heavily in Armor Tome can sometimes reduce the need for constant evasive play
- Particularly valuable in high-difficulty content with heavy enemy damage
- Essential for "facetank" builds that stay in the thick of combat
Best Use Cases
- Tank builds - Core defensive stat for facetank strategies
- Melee characters - Constantly in danger, need consistent mitigation
- New players - Passive defense that doesn't require skill
- Long boss fights - Sustained damage mitigation over time
- High difficulty runs - More valuable when enemies hit harder
- Sustain builds - Amplifies healing and regeneration efficiency
Important Considerations
- â ī¸ Diminishing Returns - Each point of armor is slightly less valuable than the last
- Armor reduction scales linearly per level, but its real effectiveness depends on enemy DPS and how often you take hits
- Works best when combined with sustain or mitigation, rather than as a stand-alone defensive layer
- Not as valuable in "perfect dodge" builds that avoid all damage
- Requires unlocking through Sir Oofie - not available at start
