Universal Tower Defense X Trait Reroll Guide
A resource-control page for players deciding when to use Trait Reroll Stones, what traits are worth keeping, and which units deserve rerolls first.
Reroll decision checklist
- Confirm the unit is S++ or S+ in the imported tier context, or has a clear support role.
- Check the recommended trait and role before rolling.
- Keep a strong role-fit trait instead of chasing perfect odds blindly.
- Recheck after Update 3.0 before spending heavily on borderline units.

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 source-backed S++ or S+ rows that already have a recommended trait listed, then check whether the unit still fits your current team.
