Trait Rarity System Explained
Mythic Traits (<0.5%)
The rarest and most powerful traits in the game. These game-changing modifiers can dramatically transform a unit's effectiveness but often come with placement limitations.
Notable Examples:
- Ruler: Massive +200% damage boost with enhanced range, limited to 1 placement
- Fission: Adds radiation DoT while boosting damage and range
- Eternal: Scales infinitely with wave progression
Best Used For:
Main damage dealers, boss killers, or specialized strategic units where maximum impact matters most.
Legendary Traits (0.5%-5%)
Powerful traits that provide significant advantages without harsh restrictions. These strike an excellent balance between power and accessibility.
Notable Examples:
- Wizard: Perfect for DoT-focused builds with +30% DoT damage
- Duelist: Critical rate and boss damage specialist
- Artificer: Maximizes relic effectiveness with +15% stats
Best Used For:
Versatile units that benefit from specific stat combinations, or when building around particular strategies.
Common Traits (≥5%)
Foundation traits that provide reliable stat improvements. While less flashy, these traits form the backbone of most effective builds.
Notable Examples:
- Enhanced: Straightforward damage increase for consistent improvement
- Agile: Cooldown reduction for faster attack cycles
- Precise: Range extension for better positioning and safety
Best Used For:
Support units, early-game progression, or when you need immediate, reliable improvements.
Trait Optimization Strategies
Trait Selection Strategy
Choosing the right trait requires understanding your unit's role and how traits synergize with their base abilities. Consider both immediate impact and long-term scaling potential.
Key Considerations:
- Unit Role: Match traits to your unit's primary function (DPS, Support, Tank)
- Base Stats: Amplify existing strengths rather than patching weaknesses
- Team Composition: Consider how traits interact with team buffs and synergies
- Game Mode: Different modes favor different trait types (Infinite vs Story vs Raids)
Reroll Investment Guide
Trait rerolling requires careful resource management. Understanding when to invest and when to settle is crucial for efficient progression.
Reroll Priority System:
- High Priority: Main DPS units in your core team composition
- Medium Priority: Key support units and secondary damage dealers
- Low Priority: Situational units or those you're still testing
- Skip: Units you plan to replace or rarely use
Pro Tip: For expensive Mythic traits, calculate expected investment using our [Trait Reroll Analyzer](/trait-reroll-analyzer) before committing resources.
Trait Synergy Combinations
Certain traits work exceptionally well with specific unit types and team compositions. Building around these synergies maximizes effectiveness.
Powerful Combinations:
- DoT Builds: Wizard or Astral traits on poison/burn units for devastating tick damage
- Boss Killers: Duelist trait combined with high base damage and critical modifiers
- Infinite Scaling: Eternal trait on units that survive long battles
- Economy Focus: Fortunate trait on your farming team for +20% income boost
Advanced Trait Mechanics
Understanding hidden mechanics and edge cases can give you a competitive advantage when building optimal team compositions.
Important Mechanics:
- Placement Limits: Mythic traits like Ruler and Astral restrict team building - plan accordingly
- DoT Stacking: Astral trait enables unique multi-stack DoT strategies
- Percentage Scaling: Damage multipliers apply after all other calculations
- Cooldown Breakpoints: Multiple cooldown reductions can reach animation lock limits
Trait Value by Game Mode
Different traits perform better in specific game modes. Optimize your trait selection based on where you're playing.
Budget-Friendly Trait Tips
Not everyone can afford to chase Mythic traits. Here's how to maximize value with smart Common and Legendary trait choices.
High-Value Budget Options:
- Lethal (5%): Excellent damage boost against low-HP enemies - nearly Legendary value
- Deadeye (2.5%): +20% range at reasonable roll rates
- Lightspeed (1.5%): Strong cooldown reduction without Mythic investment
- Enhanced/Agile/Precise: Reliable improvements you'll hit frequently
Remember: A good Common trait on your main DPS is better than no trait while chasing Mythics. Upgrade incrementally!
Frequently Asked Questions
How does trait pity system work?
After approximately 1200 trait rerolls without obtaining a Ruler trait, the pity system guarantees you'll receive one on your next roll. This system helps ensure long-term fairness for all players.
Can I have multiple Mythic traits on different units?
Yes! While traits like Ruler and Astral have placement limits (you can only have one unit with that trait deployed), you can have multiple units with Mythic traits in your collection and swap them as needed.
Which trait is best for farming?
Fortunate (+20% income) is the clear winner for farming setups. Place it on a unit in your farming team to significantly increase resource gains over time. The investment pays for itself quickly.
Do trait bonuses stack with relic bonuses?
Yes, traits and relics stack multiplicatively in most cases. For example, Artificer trait (+15% relic stats) actually increases the bonuses you get from your equipped relics, making it exceptionally valuable for well-equipped units.
Should I reroll until I get a Mythic trait?
Not necessarily. Mythic traits are powerful but expensive to obtain. For most units, a good Legendary trait like Wizard, Duelist, or Artificer provides excellent value. Focus Mythic hunting on your absolute best units only.
What's the difference between DoT damage and regular damage traits?
DoT (Damage over Time) traits like Wizard specifically boost poison, burn, and bleed effects. These are only effective on units that already apply DoT effects. Regular damage traits like Enhanced work on all damage types.
