Overview
Precision Tome increases your Critical Hit Chance, enabling critical strikes that deal significantly increased damage. When your total Crit Chance exceeds 100%, you unlock the Overcrit mechanic, allowing multiple critical hits on a single attack for exponentially higher burst damage.
How It Works: Each level of Precision Tome adds +7% Crit Chance (based on community testing and guides). This value is additive with other sources of Crit Chance from items and upgrades. When combined with Crit Damage modifiers and base damage boosts, Precision greatly amplifies overall DPS output.
Overcrit Mechanism
When your total Crit Chance exceeds 100%, the "overflow" translates into a probability to land multiple crits on a single hit, each multiplying the damage further:
- Level examples calculated at +7% per level (community-verified rate)
- Max Level (~99) is based on current community consensus; may vary by version
- At ~99 levels, total Crit Chance would reach 693%, enabling extreme Overcrit scaling
- The exact damage multiplier formulas for Overcrits are not publicly documented by developers
Community Tier Rating
Precision Tome is widely regarded as one of the strongest offensive Tomes for damage-focused builds across multiple tier lists and community discussions:
- Destructoid: Listed as a high-priority Tome for damage builds (Sep 2025)
- ProGameGuides: Noted for "scaling quickly (7% per level)" in tier discussions (Oct 2025)
- GameRant: Highlighted for Overcrit mechanics and burst potential (Oct 2025)
- Community consensus: Frequently appears in "meta" and "strong offensive" categories
Note: Tier ratings vary by source, playstyle, and game version. No official "tier list" exists from developers.
Popular Build Combinations
Precision Tome is frequently paired with other offensive Tomes in high-damage builds. Common combinations referenced in community discussions include:
- Precision + Damage + Cooldown: A popular "offensive trio" for maximizing DPS
- Precision + Luck + XP/Cursed: Another common setup focusing on item quality and progression
- Precision + Quantity: More projectiles = more chances to land crits
Note: There is no single "Holy Trinity" confirmed by developers. Build preferences vary based on character, weapon, and playstyle.
Example Weapon Synergies
Precision Tome benefits all weapons universally since Crit Chance applies to every hit. However, weapons with high hit frequency or multi-projectile attacks maximize the value:
- Multi-hit weapons (e.g., rapid-fire weapons): More hits per second = more crit rolls
- Projectile-based weapons (e.g., Shotgun, multi-projectile setups): Each projectile can crit independently
- AoE weapons: Critical hits apply to all enemies within the area
- High base damage weapons: Crits multiply already-large damage numbers
Examples are illustrative; Precision is effective across all weapon types.
Tome Synergies
Strategy Guide
- A strong offensive Tome for nearly all weapons due to universal Crit Chance benefit
- Works best when combined with high base damage or large numbers of attacks per second
- Overcrits are community-observed but not fully documented in official sources; they add significant burst potential at very high levels
- Essential for boss-killing builds that need burst damage
- Scaling accelerates as you invest more levels, especially after crossing 100% Crit Chance
- Target 100%+ Crit Chance to unlock Overcrit mechanics for maximum power spikes
Why Precision is Popular for DPS Builds
- Frequently cited as one of the strongest scaling Tomes for damage output in community discussions
- Early investment can snowball runs by boosting damage quickly in the first few minutes
- Works universally with every weapon type and character
- Crit Chance combines multiplicatively with Crit Damage and base damage for large DPS gains
- Overcrit potential at high levels provides unmatched burst damage for clearing screens and melting bosses
- Commonly paired with Damage and Cooldown in popular "offensive trio" builds
Pro Tips
- Push for 100% Crit Chance first to guarantee crits, then push higher for Overcrits
- Combine with items that grant Crit Damage for exponential scaling
- Essential for fast-clearing builds and speedruns
- Particularly powerful with multi-hit weapons (more rolls = more crits)
- If Max Level is indeed ~99, reaching that cap provides 693% Crit Chance for guaranteed multi-Overcrits
- Pairs well with Luck Tome to increase the odds of finding Crit-boosting items
Version & Accuracy Notes
- Version: Information based on v1.0.7-v1.0.17 (September-October 2025)
- +7% per level is community-verified via player testing and guides
- Max Level (~99) is based on recent community consensus; earlier discussions suggested different caps
- Overcrit mechanics are player-observed and confirmed by media sources, but exact formulas are not publicly documented
- Tier ratings vary by source; no official tier list exists from developers
- Game is in active development; values and mechanics may change in future patches
