This Universal Tower Defense Z tier list is the Update 4.0 meta home for Roblox players searching UTD tier list, universal tower defense tier list, utdz tierlist, or tier list utd. It answers who to build, who to reroll, and which child page owns the full S/A/B tables.
The Universe begins. Welcome to Universal Tower Defense! Update 4.0 added Bleach Boundless carries, Persona secrets, and Spider-Man synchro fusions — the largest shift since global launch in December 2025. Grab free Gems and trait rerolls from the UTD Z codes list before chasing banners.
Use this page for the overview and mode map, then open the unit tier list for DPS ranks or the trait tier list for Ruler / Eternal / Sacred pity. Cross-check units, traits, relics, and enemies when you lock a team.
Most UTD Z tier list visits want three answers before scrolling: best unit right now, best trait to pity, and whether an old Universal Tower Defense X clip still applies.

| Question | Short answer | Go deeper |
|---|---|---|
| Best units now? | Spider synchros · Bleach Boundless · Persona secrets | Unit tier list |
| Best trait to pity? | Sacred mid-game · Ruler endgame · Eternal Infinite | Trait tier list |
| Starter / free carry? | Berserker + Air coverage (Zora) | Beginner guide |
| X list still valid? | No — use Z Update 4.0 only | #x-vs-z |
This Universal Tower Defense Z tier list hub links every ranked board. Unit pages cover Story, Infinite, and Raid. Trait pages cover reroll value and pity. Relic set value stays on the relics guide until a dedicated relic tier page ships.
| Tier list | Focus | Link |
|---|---|---|
| ⚔️ Units | Story / Infinite / Raid meta | Unit tier list |
| ✨ Traits | Reroll value · pity targets | Trait tier list |
| 📦 Relics | Set bonuses · farming priority | Relics guide |
| 👹 Enemies | Counters by type | Enemies guide |
| 📈 Growth | Etherealize · Evolution order | Etherealize · Evolution |
The full Universal Tower Defense Z unit tier list lives on its own URL so mythic notes, synchro math, and mode tables stay scannable. Here is the Update 4.0 ceiling preview — Pending review until your own clears confirm.
| Tier | Unit / line | Why it matters |
|---|---|---|
| S | Iron Spider / Symbiote Spider | Synchro ceiling for Update 4.0 DPS and web CC |
| S | Moonless Sky → The Almighty | Bleach DoT / buff line — top Story and Infinite stacks |
| S | Visionary (Unrivaled) / Gremmy | Clone Hybrid core for Bleach teams |
| S | Trickster (Phantom) | Persona secret burst and team amp |
| S | Blanco Beast | Boundless Hill/Ground carry that stays strong mid-build |
| A | Berserker | Mythic Armored staple — keep etherealizing |
Persona cores (Trickster + support buffers) and Spider synchro cores currently fight for strongest clear speed. Bleach stacks around Visionary clones plus The Almighty DoT when you can place multiple summons.
Do not force every S-tier name onto one board — coverage beats rarity. Pair any DPS core with Hybrid/Air answers from the enemies guide.

Trait priority decides whether your UTD tier list carry actually hits its DPS ceiling. Each unit has two slots — save pity for the carry you will Etherealize.
| Tier | Trait | Pity | Best use |
|---|---|---|---|
| S | Ruler | 1250 | Solo carry DPS — one placement limit |
| S | Eternal | 625 | Infinite per-wave scaling |
| S | Fission | 833 | Radiation DoT / status teams |
| A | Sacred | 416 | Budget multi-place Story teams |
| A | Duelist | 156 | Raid boss damage |
Early Universal Tower Defense Z: Sacred or Duelist on your best Hybrid. Mid-game: lock Sacred, then chase Ruler on slot two. Infinite mains: Eternal before Ruler when wave growth beats burst.
Full pity tables and B-tier fillers live on the trait tier list. Effect text stays on the traits guide.
Mode tags change who sits S-tier. A Story burst secret can fall a letter in Infinite if it lacks per-wave scaling.
| Mode | Tag | Tier list priority |
|---|---|---|
| Story | 📖 | Hybrid coverage · boss burst · enemies counters |
| Infinite | ♾️ | Eternal trait · wave scaling · SPA efficiency |
| Raid | ⚔️ | Co-op DPS · clear speed · evolution material yield |
| Challenge | 🎯 | Rule-specific picks · niche S-tier units |
| Update 4.0 events | 🕸️ | Banner / synchro units · Pending until verified |
Story rewards Hybrid coverage and boss burst — Flying chapters punish Ground-only boards. Infinite rewards Eternal and SPA-efficient farmers. Raids reward clear speed for evolution shops and relic sets.
Event modes (Spider-Man extraction, Persona, Reapers vs Hollows) may temporarily inflate off-meta units — note the event context before liquidating older carries.
GSC and autocomplete still surface utd tier list, universal tower defense tier list, utdz tierlist, tier list utd, and universal tower defense x tier list 4.0. Those queries should resolve to this Universal Tower Defense Z hub — not outdated X-only boards.
Roblox experience titles mix X and Z tags. Canonical Update 4.0 content for July 2026 is Universal Tower Defense Z. If a clip never shows Bleach Boundless or Spider synchros, treat it as historical and jump to the unit tier list.
Every board under this hub uses community-reported clears tagged by verification date. S-tier units must perform in Story and at least one endgame mode — Infinite or Raid — unless labeled mode-specific.
Wave clear, boss damage, and placement type (Hybrid vs Ground-only) outrank hype thumbnails. Traits and relics multiply base stats — a Mythic with Ruler can out-DPS a bare Boundless unit.
We demote units on direct nerfs in updates. Systemic changes — trait rates, relic shops — can move ranks without stat edits. Wait 48–72 hours after banners before treating day-one takes as locked.
| Signal | Weight | Notes |
|---|---|---|
| DPS / wave clear | High | Story and Infinite scaling in Universal Tower Defense Z |
| Boss damage | High | Legend acts and raid timers |
| Placement type | High | Hybrid ranks above Ground-only for general use |
| Trait synergy | Medium | Ruler / Eternal / Duelist amplify listed tiers |
| Obtain cost | Medium | Event exclusives rank lower if F2P cannot farm them |
Gold generators and placement-cost reducers often decide long Infinite sessions even when absent from the main unit tier list. A B-tier farmer with economy traits and Legs relics can outvalue an unbuilt S-tier DPS.
