As a new Universal Tower Defense Z player, you have limited Trait Rerolls and must spend them wisely. Chasing Ruler (0.1% chance) with 100 rerolls is a recipe for frustration — the probability of success is only about 9%. Instead, this guide provides a beginner-friendly trait priority plan that maximizes your early progression with limited resources. By following the correct order — Fortunate on farm first, then Prodigy on DPS, then upgrading to A-tier traits — you ensure every Reroll provides meaningful value.
Beginner Trait Priority List
Follow this exact order when spending your Trait Rerolls. Each step is designed to provide the maximum impact at your current account stage:
| Priority | Target | Chance | Rerolls Needed | Impact | When to Chase |
|---|---|---|---|---|---|
| 1 | Fortunate on Farm | 1% | ~100 | Economy boost funds everything | Week 1-2 |
| 2 | Prodigy on DPS | 2% | ~50 | Accessible DPS boost | Week 2-3 |
| 3 | Wizard on elemental DPS | 1.5% | ~67 | If your DPS is elemental | Month 1 |
| 4 | Duelist on boss specialist | 0.8% | ~125 | For Raid content | Month 2 |
| 5 | Sacred on expensive units | 0.3% | ~333 | Mid-game optimization | Month 3 |
| 6 | Astral on support | 0.45% | ~222 | Team buff extension | Month 3 |
| 7 | Ruler on primary DPS | 0.1% | ~1000 | Endgame goal | Month 4+ |
Why Fortunate First — The Economy Argument
The Fortunate trait on a farm unit provides +20% Gem income. This income boost compounds over every wave, effectively giving you more resources to spend on everything — including more Rerolls:
| Timeframe | Extra Gems from Fortunate | What It Funds |
|---|---|---|
| 1 day | 60K+ | ~1 Challenge run worth of Gems |
| 1 week | 420K+ | ~1 featured banner pull |
| 1 month | 1.8M+ | ~3 featured pulls or 700 Rerolls |
| 3 months | 5.4M+ | Full featured pity + surplus Rerolls |
Fortunate pays for itself and then some. A farm unit with Fortunate generates 1.8M+ extra Gems per month, which can fund additional Rerolls or banner pulls. Always roll this first before any other trait.
What If I Do Not Have a Farm Unit?
If you have not obtained a dedicated farm unit yet, wait. Do not spend Rerolls on DPS traits until you have a farm unit to put Fortunate on. Use active codes for free Rerolls while you save up, and summon for a farm unit on the next featured banner.
Beginner Reroll Budget Plan
This plan assumes approximately 6000+ Rerolls per month from farming (see our reroll farming guide):
| Week | Reroll Budget | Action | Target | Expected Outcome |
|---|---|---|---|---|
| Week 1 | 0-200 | Roll Fortunate on farm (1%) | ~100 Rerolls | High probability of success |
| Week 2-3 | 200-500 | Roll Prodigy on primary DPS (2%) | ~50 Rerolls | Very likely to succeed |
| Month 2 | 500-1000 | Roll Duelist for Raid DPS (0.8%) | ~125 Rerolls | Good chance of success |
| Month 3 | 1000-2000 | Roll Sacred on primary DPS (0.3%) | ~333 Rerolls | Moderate chance |
| Month 4+ | 2000+ | Start saving for Ruler (0.1%) | ~1000 Rerolls | ~63% probability |
Common Beginner Mistakes with Traits
| Mistake | Why It Hurts | Correct Approach |
|---|---|---|
| Chasing Ruler with 100 rerolls | 0.1% chance = 90% chance of failure | Save 1000+ rerolls first |
| Rerolling farm unit off Fortunate | Loses permanent income | Never reroll Fortunate farm |
| Rolling traits on C/D tier units | Wasted on units you will replace | Only roll on S and A tier units |
| Using Ruler Ticket on wrong unit | Ruler Tickets are extremely rare | Use on primary S-tier DPS |
| Rolling before getting farm unit | No economy boost to fund future | Get farm first, then Fortunate |
| Spending all Rerolls immediately | No reserve for new units | Keep 100+ in reserve |
The Ruler Trap for Beginners
| Scenario | Rerolls | Ruler Probability | Outcome |
|---|---|---|---|
| Beginner chases Ruler | 100 | ~9.5% | Likely 100 wasted Rerolls |
| Beginner rolls Fortunate + Prodigy | 150 | N/A | Economy + DPS improvement |
| Veteran saves for Ruler | 1000 | ~63% | Meaningful chance of success |
Chasing Ruler with fewer than 500 Rerolls is statistically a waste. The probability is too low for the investment. Focus on achievable traits that provide guaranteed value at higher probabilities.
Trait Priority by Account Stage
| Account Stage | Reroll Priority | Save For |
|---|---|---|
| Week 1-2 | Fortunate (farm) | — |
| Month 1 | Prodigy or Wizard (DPS) | — |
| Month 2-3 | Duelist (Raid DPS) | Sacred |
| Month 4+ | Sacred (expensive units) | Ruler |
| Month 6+ | Ruler (primary DPS) | — |
This timeline assumes 2-3 hours of daily active play. If you play less, extend each stage proportionally. The key principle remains: never skip Fortunate, and never chase Ruler before you have 1000+ Rerolls saved.
When to Stop Rerolling
| Current Trait | Keep If | Reroll If | Target |
|---|---|---|---|
| No trait | Always reroll | — | Any B+ trait |
| Prodigy | On DPS carry | If 500+ rerolls saved | Sacred or Duelist |
| Wizard | On elemental DPS | If 500+ rerolls saved | Sacred or Prodigy |
| Duelist | On boss specialist | Never (perfect) | — |
| Fortunate | On farm unit | Never (mandatory) | — |
| Sacred | On any DPS | Only if 1000+ rerolls and primary DPS | Ruler |
| Astral | On support | Never (perfect) | — |
| Ruler | On any DPS | Never (best trait) | — |
The general rule: if you have a B+ trait on the right unit, keep it. The cost of upgrading from Prodigy to Sacred is ~333 Rerolls for a 25% DPS improvement. This is a good trade only if you have a large Reroll surplus.
Trait Synergy Combinations
Understanding how traits interact with unit abilities and relic sets is crucial for maximizing team performance. Some trait combinations create multiplicative effects that far exceed the sum of their individual bonuses:
| Trait + Relic Set | Combined Effect | Effective DPS Increase | Best Unit |
|---|---|---|---|
| Ruler + Fused Warrior set | +200% DMG + -7.5% CD + 15% Range | +230%+ | Joyful Captain |
| Duelist + Warlord set | +35% Boss DMG + Crit DMG bonus | +50%+ (boss) | Super Roku |
| Sacred + Any DPS set | +25% DMG -15% Cost + set bonus | +35%+ | Ancient Mage |
| Fortunate + HP relics | +20% Income + survivability | +20% income | Farm units |
| Astral + Support set | +20% Buff Duration + set bonus | +25%+ team DPS | Support units |
Trait Stacking Mechanics
Traits apply their bonuses multiplicatively with etherealization and relic bonuses, but additively with other traits on the same unit. Since each unit can only have one trait, the stacking question is about how traits interact with other systems:
| System | Interaction with Traits | Example |
|---|---|---|
| Etherealization | Multiplicative with trait | Ruler (+200%) x Full Etherealized (+500%) = 1500% total |
| Relic Sets | Additive with some stats, multiplicative with others | Fused Warrior -7.5% CD multiplies with Ruler -20% CD |
| Evolution | Additive base stat increase | Evolution doubles base, Ruler triples it |
| Team Buffs | Multiplicative with all | Support buff x Ruler x Etherealized = massive |
Common Trait Synergy Mistakes
| Mistake | What Players Do | Correct Approach | Why |
|---|---|---|---|
| Ruler on Farm unit | +200% DMG on unit with no DPS | Use Fortunate for +20% income | Farm units do not deal meaningful damage |
| Duelist on Story Mode team | +35% boss damage for wave clearing | Use Ruler or Sacred instead | Boss damage is wasted on regular waves |
| Sacred on cheap units | -15% cost on already cheap deployment | Use Prodigy for +30% DMG | Cost reduction is less valuable on cheap units |
| Fortunate on DPS unit | +20% income on unit with no farm ability | Use Ruler or Sacred for damage | DPS units do not generate income |
Trait Roll Probability Deep Dive
Understanding the exact probabilities helps you plan your Reroll budget:
| Trait | Roll Chance | Expected Rerolls | 95% Confidence Rerolls | Reroll Value (Gems equivalent) |
|---|---|---|---|---|
| Ruler | 0.1% | 1,000 | 3,000 | ~5,000 Gems |
| Astral | 0.45% | 222 | 667 | ~1,110 Gems |
| Sacred | 0.3% | 333 | 1,000 | ~1,665 Gems |
| Duelist | 0.8% | 125 | 375 | ~625 Gems |
| Fortunate | 1.0% | 100 | 300 | ~500 Gems |
| Wizard | 0.5% | 200 | 600 | ~1,000 Gems |
| Prodigy | 3.0% | 33 | 100 | ~165 Gems |
Reroll Budget Planning
| Target Trait | Minimum Rerolls | Recommended Rerolls | Farming Time | Monthly Reroll Income |
|---|---|---|---|---|
| Fortunate | 100 | 200-300 | 3-5 days | 5,580+/month |
| Prodigy | 33 | 100 | 1-2 days | Easy to chase |
| Duelist | 125 | 250-375 | 5-7 days | Moderate |
| Sacred | 333 | 500-1000 | 2-3 weeks | Significant investment |
| Astral | 222 | 400-667 | 2-3 weeks | Significant investment |
| Ruler | 1000 | 2000-3000 | 4-8 weeks | Long-term chase only |
Trait Transfer and Pity System
Currently, UTDZ does not have a trait transfer system or a pity mechanic for trait rolls. Every roll is independent with the same probability:
| Feature | Status | Impact |
|---|---|---|
| Trait Transfer | Not available | Cannot move traits between units |
| Trait Pity | Not available | No guaranteed Ruler after X rolls |
| Trait Lock | Not available | Cannot protect a good trait while rerolling |
| Stat Lock (for Relics) | Available | Can lock relic substats while rerolling |
The absence of a pity system means that Ruler traits are purely probability-based. Some players get Ruler in 50 rolls; others take 5000+. This variance is why Ruler Tickets from codes are so valuable — they guarantee the result.
Advanced Trait Strategies
When to Settle for a Good Trait
| Scenario | Settle For | Keep Chasing? | Reason |
|---|---|---|---|
| Got Prodigy on primary DPS | Yes, settle temporarily | Chase Ruler later | Prodigy provides +30% while you save Rerolls |
| Got Sacred on Hill DPS | Yes, consider settling | Maybe chase Ruler | Sacred is excellent on expensive Hill units |
| Got Duelist on Raid specialist | Yes, settle permanently | No | Duelist is BiS for Raid boss specialists |
| Got Wizard on any unit | Maybe settle temporarily | Yes, chase better | Wizard is mediocre on most units |
| Got no trait after 500 rolls | Keep rolling | Absolutely | 500 rolls without any trait is extremely unlikely |
Trait Priority by Account Stage
| Account Stage | Trait Priority | Reroll Budget | Why |
|---|---|---|---|
| New (0-1 S-tier) | Fortunate on Farm | 200 Rerolls | Economy first — +20% income |
| Early (1 S-tier) | Prodigy on DPS | 100 Rerolls | Quick DPS boost for content clearing |
| Mid (2+ S-tier) | Sacred or Duelist on specialists | 500 Rerolls | Role-specific optimization |
| Late (3+ S-tier) | Ruler chase on primary DPS | 2000+ Rerolls | Endgame optimization |
| Endgame (all content cleared) | Ruler on all S-tier units | 5000+ Rerolls | Maximum optimization |
Frequently Asked Questions
How many rerolls do I need as a beginner? Save at least 100 for Fortunate, then 50 for Prodigy. Do not spend beyond your budget chasing low-probability traits. See our reroll farming guide for the complete farming schedule.
Should I roll traits on my starter units? No — starter units will be replaced. Only roll on S and A tier units that you plan to keep long-term. Rolling on a C-tier unit wastes Rerolls that could go toward your permanent team.
What if I accidentally roll a good trait on the wrong unit? A good trait on any unit is better than no trait. Keep the unit and use it until you can roll the same or better on your ideal target. For example, Prodigy on a B-tier unit still provides +30% damage.
When should I start saving for Ruler? After you have Fortunate on farm and a B+ trait on your primary DPS. This typically happens around month 2-3. See our reroll guide for detailed saving strategies.
Can I use Ruler Tickets from codes on any unit? Yes, but always use them on your primary S-tier DPS carry. Ruler Tickets are extremely rare — using one on a support or farm unit wastes the +200% DMG bonus. Check our codes page for active Ruler Ticket rewards.
