Universal Tower Defense X Trait Reroll FAQ
Rerolling is a cost decision, not just a tier-list decision.
When should I use Trait Reroll Stones?
Use Trait Reroll Stones after the unit is already a long-term carry, support, or utility pick. Do not spend heavily on temporary early-game units.
When should I stop rerolling?
Stop when the trait fits the unit role and the next upgrade would require chasing very low listed odds without a clear long-term payoff.
Which units deserve rerolls first?
Start with S++ or S+ units that already have a recommended trait, then check whether the unit still fits your current team.
