Quick answer

The safest UTDX keeps are the S-tier cores: Love Goddess, Prodigy Mage (Apprentice), Karbonoto (Sage), Sasku (Great War), and Virtual Idol (Superstar). Build A-tier units when their trait, relic, and role fit your team; save deep rerolls for units you will use across modes.

Updated June 13, 2026. Use this before spending rerolls or other scarce build resources. Confidence is medium because Roblox balance and community testing can move quickly after updates.

Universal Tower Defense X Tier List by Keep Priority

Meta core

The first units to keep and invest in when you have them. These picks bring team-defining damage, support, or wave control.

Build around

Worth building when the trait, relic, and team slot make sense. Do not force every A-tier unit if it duplicates a role you already cover.

Useful progression

Good for story clears, farming, or filling missing roles while your account grows. Replace them when you pull a clearer S/A core.

Replace first

Use only as temporary fillers. Avoid spending scarce rerolls or premium relic setup here unless you have no better option.

Best Picks for Beginners

Redeem active UTDX codes before summoning or rerolling so your Gem, Trait Reroll, and Relic Reroll budget is clear.
Build one reliable damage unit, then add support or farm value; a team of only damage dealers can stall.
Do not chase perfect traits on a unit you may replace soon. Save rerolls until you know the unit has a long-term slot.

Strong Late-Game Picks

Spend deep Trait Rerolls and Relic Rerolls on S-tier cores or A-tier units you use in several modes.
Match relics to the unit role: boss DPS, wave clear, support, or farming.
Treat fresh event carries carefully after updates; build them if they fill a role, not just because they are new.

What Changed

June 13: First compact UTDX unit tier list, focused on keep, build, and reroll decisions.
Relic and trait notes stay tied to unit decisions instead of pretending there is one best setup for every account.

FAQ

Who should I build first in Universal Tower Defense X?

Start with S-tier units if you own them. If not, build an A-tier unit that fills a missing role, then save major rerolls for a unit you will use in more than one mode.

Should I spend Trait Rerolls on every UTDX unit?

No. Redeem active codes first, then spend Trait Rerolls on long-term units or key supports. Early fillers can clear content without perfect traits.

Why is this UTDX tier list marked medium confidence?

UTDX moves quickly, and unit value can shift with updates, traits, relics, and event rewards. Use this as a practical keep/build priority list, not a permanent ranking.
