Traits
The trait system in UTDZ lets you reroll unit traits for powerful stat boosts. With probabilities ranging from 0.1% (Ruler) to 1% (Fortunate), knowing which traits to chase and when to reroll is essential for progression.

Core Mechanics
Traits are rerolled using Trait Reroll tokens. Each roll randomly assigns one trait from the pool. Higher-value traits (Ruler, Astral, Sacred) have extremely low probabilities, so farming thousands of rerolls is necessary.
Advantages
The right trait can double or triple a unit's effectiveness. Ruler on a main DPS provides +200% damage, while Fortunate on a farm unit boosts Gem income by 20%. Traits are multiplicative with Etherealization and Relic bonuses.
Challenges & Weaknesses
Rerolling is expensive — chasing Ruler requires ~1000 Rerolls on average (0.1% chance). Bad rolls on mid-tier units waste resources. There is no pity system, so results are purely RNG.

Quick Tips
Roll Fortunate on farm units first — the income boost pays for itself.
Only chase Ruler after confirming your main carry unit — it's wasted on fillers.
Farm 2500+ Rerolls weekly using Challenges and AFK Infinite Mode.
Sacred is an excellent alternative to Ruler for expensive units (cost reduction).
Don't reroll a good trait for a slightly better one — the expected value is negative.
