Universal Tower Defense X Traits Tier List
All UTDX traits ranked S through D by DPS boost percentage, reroll cost efficiency, role synergy, and wave-band performance. Filter by type, search by name. This ranks traits: the passive modifiers you roll for each unit. The units tier list ranks the tower units themselves.
Traits Tier List quick answer
S tier: Annihilation Surge and Void Resonance for DPS carries; Apex Control for Water God. A tier CC on Water God adds more Wave 100 value than an S tier DPS trait on a second carry. Reroll order: CC unit first, main carry second, support third.
Trait type by unit role: quick reference
Every unit role has one correct trait type. Assigning the wrong type loses 60 to 80% of potential trait value even at S tier quality. This table maps the assignment.
| Unit Role | Correct Trait Type | Priority Tier Target | Wrong Type Cost | Example Unit |
|---|---|---|---|---|
| Boss-killer DPS | DPS (Annihilation Surge) | S tier | Support/Farm trait loses ~28% of carry output | First Emperor, Alpha Devil |
| Ground DPS carry | DPS or Cooldown | A,S tier | CC trait on a DPS carry: zero slow value, lost DPS | Ancient Shinobi, Crow Shinobi |
| CC / Control | CC (Apex Control / Glacial Extension) | A,S tier | DPS trait loses all slow extension; boss contact window unchanged | Water God, Ice Empress |
| Support / Aura | Support (Aura Amplifier) | A tier | DPS trait on support: small direct damage, zero aura improvement | Virtual Idol, Mimicry Sorcerer |
| Economy / Farm | Farm (Economy Surge) | B tier | Any combat trait on farm unit wastes reroll resources: farm units don't fight | Bulmo, Fastcart |
| Hybrid cleanup | DPS or Cooldown | B tier | Farm trait: cleanup units need attack output not economy | Devil Hunter, Ant King |
| Hill DPS | DPS or Cooldown | A tier | Support/CC trait: no synergy without aura or slow role | King Sailor |
Trait rerolling strategy by account stage
Early accounts (Wave 1 to 20 consistent, no Mythic units): do not reroll traits yet. Reroll materials should go toward unit acquisition banners. The DPS gap between a Common trait and a Legendary trait on a B tier unit is smaller than the gap between having and not having a control unit. Hold all traits until Water God or Ice Empress is in the roster.
Mid accounts (Wave 50 consistent, one Mythic unit): start one targeted reroll session on the control unit. Aim for Frost Anchor or Glacial Extension on Ice Empress before chasing DPS traits on carries. A single A tier CC trait here changes Wave 80 clear rate more than upgrading any DPS trait.
Late accounts (Wave 80 consistent, Water God acquired): reroll Water God first toward Apex Control or Glacial Extension, then reroll the main carry toward Annihilation Surge. The priority order is not negotiable: the CC trait on Water God is the highest Wave 100 ROI item in the entire account progression path.
Endgame accounts (Wave 100 cleared, farming): clean up secondary units. Reroll support toward Aura Amplifier, farm units toward Economy Surge, secondary carries toward Eternal Haste. At this stage the reroll ROI is incremental rather than decisive: multiple small improvements rather than one critical upgrade.
Why the wrong trait type is worse than a low-rarity correct type
A Legendary DPS trait on Water God gives +28% damage to a unit whose primary job is slow duration. That +28% damage contributes roughly 147 DPS in a boss encounter where Water God's base DPS is around 521. But the boss contact window that Water God unlocks through its slow effect is worth approximately 5,000 to 6,500 additional DPS-seconds from the carry per encounter. An A tier CC trait that adds 1.6 seconds of slow creates far more carry damage than a Legendary DPS trait on the same unit.
The trait type mistake is the most common trait error in community discussions. Players see a Legendary trait on their Water God and feel good about it without asking whether it serves the unit's actual job. Trait value is not purely about rarity tier: it requires matching type to role first, then targeting high rarity within the correct type.
The same logic applies in reverse: a Legendary CC trait on First Emperor is wasted because First Emperor has no slow mechanic to extend. Even if the slow duration bonus shows up on the stat screen, it produces zero combat output because First Emperor never applies a slow effect. Always match type to role, then chase rarity.

Trait depth notes
The tier positions in this list treat all traits of the same type as equivalent within their rarity band: Annihilation Surge and Void Resonance are both S tier DPS because both deliver the highest available DPS multiplier, even though their mechanics differ. Players who want to distinguish between them should check which applies to their specific carry: Annihilation Surge scales with unit level (better at Level 5), while Void Resonance applies a flat bonus that is proportionally stronger at lower upgrade levels. For Level 5 carries, Annihilation Surge pulls ahead. For Level 3 carries, Void Resonance is marginally better.
CC traits deserve more attention than they receive in community discussions because the tier list comparison for CC is unusual. A Legendary CC trait is not compared against other CC traits: it is compared against what it does to the DPS output of the entire team by extending the boss contact window. When Water God gets Apex Control and gains 2.8 seconds of additional slow duration, every carry in the build fires one more partial cycle. That indirect DPS uplift often exceeds the direct DPS gain from upgrading a carry's trait by one rarity tier.
The Cooldown trait category is the most misunderstood. A 15% cooldown reduction does not produce exactly 15% more DPS: it depends on the cooldown math. A unit with a 2.8s cooldown (Alpha Devil) gains more from a 15% reduction than a unit with a 1.2s cooldown (Ancient Shinobi), because the same number of attack cycles occupies less time, creating more cycles in a fixed boss contact window. Run the calculation on your specific carry before deciding between a Cooldown trait and a DPS trait of equal rarity. The wave-100-guide page documents the specific calculation for the attempt-27 build.
Farm traits are frequently dismissed entirely, which creates an error in the opposite direction. An A tier Farm trait on Bulmo does not affect combat directly, but it changes the timing of when the carry reaches Level 4: which affects every wave from that point forward. Over 40 Wave 50 farm runs, an A tier Farm trait on a dedicated farm unit compounds into carry upgrade opportunities that are more useful than slightly better boss-encounter DPS on a unit that is already at the damage ceiling for that wave band. Match trait type to unit role first; farm units are not exceptions to that rule.
FAQ
What are traits in Universal Tower Defense X?
Traits are passive modifier slots attached to individual units that boost specific stats: DPS, cooldown, control duration, economy output, or support aura strength. Each unit holds one active trait obtained through rerolling.
How is this traits tier list different from the units tier list?
The units tier list ranks the tower units you place on the map. This list ranks the passive modifiers you attach to those units. Use both together: unit tier tells you which unit to get next, trait tier tells you which trait to roll for after you have it.
Which trait type should I prioritize for carry units?
DPS traits: Annihilation Surge (S tier) or Eternal Haste (A tier). These directly increase the damage output that determines Wave 100 boss kill time. Do not put CC or Support traits on carries.
What trait should I put on Water God?
An S or A tier CC trait: Apex Control (S) or Glacial Extension (A). These extend the slow window that determines Wave 100 boss survivability. See the wave-100-guide for the exact calculation.
Should I reroll traits before or after maxing unit upgrades?
After. A fully upgraded unit with a B tier trait outperforms a base-level unit with an S tier trait. Trait rerolling is a late refinement step after the roster is established.
How many rerolls does it take to hit an S tier trait?
Approximately 1 in 60 on average. The 95th-percentile unlucky run is about 180 rerolls. Have at least 2x the expected cost saved before targeting S tier.
Can I use a Support trait on a DPS unit?
Technically yes, but it almost always loses 60 to 80% of trait value versus using the correct DPS type. Match type to role first, then chase rarity within the correct type.
Are Farm traits worth targeting?
Yes, on dedicated farm units like Bulmo or Fastcart. An A tier Farm trait on a farm unit compounds across many runs. Zero value on carry, control, or support units.
What is the most overrated trait in the community meta?
Multi-Target Cleave. It sounds impactful but splits damage across targets instead of concentrating on the boss, reducing kill speed in every Wave 80+ boss encounter tested.
Does trait rarity correspond directly to tier?
Not directly. Rarity determines bonus magnitude; tier reflects overall combat value combining rarity, type, and unit synergy. An A tier CC trait at Legendary quality outperforms an S tier DPS trait at Common quality on a carry unit once the type match is correct.
How do I use the search and filter together?
Filter by your needed type first (e.g., CC), then type your target unit in the search box to see which traits apply. This answers the practical question: which CC trait should I roll for and which unit gets it?
