Overview
The Knockback Tome increases the distance enemies are pushed back when hit by your attacks. This effect is weapon-dependent - it only works with weapons that have built-in knockback effects in their upgrade paths.
The exact per-level percentage increase is not publicly documented in official sources. Community analyses suggest that most Tomes (except Damage Tome which uses multiplicative scaling) stack additively rather than multiplicatively.
How Knockback Works
- Weapon Dependency: Only affects weapons that have knockback in their upgrade list or base effects
- Distance Scaling: Increases how far enemies are pushed back per hit
- Likely Additive Stacking: Based on community analysis, levels stack additively (not multiplicatively)
- Crowd Control Tool: Creates space between you and enemies, useful for defensive positioning
- Boss Limitations: Developers have mentioned plans to limit maximum knockback on boss enemies
Verified Compatible Weapons
These weapons have been verified to have Knockback in their upgrade paths, making them compatible with Knockback Tome:
Synergy Guide
Strategy Guide
- Weapon verification first: Check if your weapon has knockback before investing any points
- Defensive playstyles: Great for creating space when overwhelmed by enemies
- Melee builds: Essential for creating safe attack windows after each strike
- Positioning control: Can protect objectives or funnel enemies into kill zones
- Boss fights with adds: Valuable for managing additional enemies during boss encounters
- Community strategy note: Commonly discussed in high-density run strategies, though effectiveness varies by build
When to Invest
- Using verified knockback weapons - Sword, Shotgun, Aegis, Tornado, or other confirmed weapons
- Melee character builds - Create space after each strike for safety
- Defensive strategies - Control enemy positioning and flow to survive longer
- High enemy density runs - More enemies = more value from crowd control effects
- Hybrid builds - Combine offensive power with positioning control for balanced play
Critical Warnings
- ⚠️ Weapon Dependency - Completely ineffective if your weapon lacks knockback mechanics
- ⚠️ Check Before Investing - Always verify your weapon has knockback in its upgrade list first
- ⚠️ Can Backfire - May push enemies into unfavorable positions or spread them too far apart
- ⚠️ Situational Value - Strong when compatible, but not universally useful like Damage or Health
- ⚠️ Build Conflicts - Some builds actively avoid knockback to keep enemies grouped for AoE damage
- ⚠️ Boss Limitations - Developers are implementing limits on maximum boss knockback (recent Reddit discussion)
Developer & Community Notes
- Recent Developer Note: Plans to limit maximum knockback on boss enemies mentioned in Reddit discussion (October 2025)
- Scaling Uncertainty: Exact per-level percentage not publicly documented; community estimates vary
- Max Level Debate: Community consensus on Tome level caps is inconsistent; verify in-game pause menu
- Stacking Mechanics: Most community analysis suggests additive stacking (unlike Damage Tome's multiplicative scaling)
Additional Notes
Considered situational but very effective when properly synergized with compatible weapons. The Tome's value is binary: either incredibly useful or completely wasted depending on weapon selection. Can make melee runs significantly safer by creating breathing room after each strike. Always prioritize verifying weapon compatibility before investing Tome points into Knockback.
