Universal Tower Defense X Best Traits
A reroll-priority page for players searching best traits, trait tier list, Ruler odds, and which units deserve expensive Trait Reroll Stones.
Fast rule: pick the unit first, then chase the trait. Rerolling a weak or temporary unit wastes scarce Trait Reroll Stones even if the trait itself is strong.

Universal Tower Defense X Best Traits FAQ
Short answers for trait priority and reroll risk.
What is the best trait in Universal Tower Defense X?
Ruler is the highest-impact listed mythic trait for many carry units because the source-backed table lists a large damage, cooldown, and range package. It is still not automatic for every unit because it has a one-unit limit.
Should I reroll until I get Ruler?
Only on a long-term carry. The listed Ruler chance is 0.1%, so spending rerolls on a temporary unit is a bad resource trade.
Are support traits different from DPS traits?
Yes. Cooldown, range, income, or affliction effects can matter more on support and utility units than pure damage.
