UTDX Optimizer — Universal Tower Defense X Team Composition Optimizer

How the UTDX optimizer scores your team

Most team-building tools in Roblox games show you raw DPS numbers and expect you to do the role-coverage math yourself. The UTDX optimizer works from the other direction: it starts with what your stage actually demands, then finds the unit set that covers those demands at the lowest gold cost.

The scoring has three parts. First, each unit earns a base score from its DPS at your chosen upgrade level divided by its placement cost: the units that deal the most damage per gold spent start ahead. Second, role-match multipliers push units that fill your stated gaps to the top: if you flagged "boss killer" as a need, boss-killer units score 1.5× higher for that slot. Third, the stage type adjusts the weight of control and support: co-op stages amplify utility scores because Water God (Primordial)'s slow field benefits every player's carries, also yours.

The optimizer then builds the team greedily from the highest-scoring unit down, subtracting cost from budget after each pick, and stopping once either the slot count is reached or the budget runs out. This means the first unit in the list is always the single highest-use pick given your constraints: useful on its own if you only have one slot left to fill.

One thing the optimizer deliberately does not do is maximise raw DPS at the expense of role coverage. Five damage dealers with no control or support is a team that works on wave 15 and leaks on wave 50. The wave guide shows the DPS thresholds that actually matter at each checkpoint, and the optimizer is calibrated so a team that covers DPS, control, and support within budget passes those thresholds: rather than producing a theoretical DPS ceiling you cannot sustain.

Which optimizer settings to use for each stage type

The stage type dropdown changes how the optimizer weights control and support versus raw DPS. Here is what each setting does and when to use it.

For your first run, set your stage to Story, budget to 10,000, level to 3, and tick DPS carry plus Support. This gives you the baseline team most UTDX beginners can afford and sustain through wave 30.

UTDX optimizer versus the DPS calculator: which to use

The DPS calculator answers a specific question: given these units at these levels with these buffs, what is the total team DPS? You use it when you already know which units you want and need to verify the output before spending upgrades.

The optimizer answers the upstream question: given this stage type and budget, which units should I pick? You use it before opening the DPS calculator: run the optimizer to get a team, then plug those units into the DPS calculator to confirm the numbers before you commit. The two tools are designed to work in sequence, not as alternatives.

The best-mythic comparison handles a third case: when you already know you want a Mythic and need to choose between two specific options. It compares mythics on a five-axis radar rather than making a budget-constrained selection. If your question is "which mythic fits my team gap," use the best-mythic tool. If your question is "what is the best team I can build for 12,000 gold on a boss wave," use the optimizer.

Reading the budget output and leftovers

After the optimizer runs, it shows total team cost, team DPS at your upgrade level, budget remaining, and the roles covered. The "budget remaining" number matters because UTDX generates income during a run: a team that costs 9,200 of your 12,000 gold leaves 2,800 available for an upgrade or a fourth unit you place mid-run once economy catches up.

Teams with large remainders are not waste: they are flexibility. A 3,000-gold remainder at wave 20 is often the right call because income units like Bulmo or Fastcart generate enough gold to fill the fourth slot from run proceeds rather than startup funds. The optimizer includes farm-role units in its scoring precisely because building a strong early economy often produces a better wave-40 outcome than over-spending on DPS at placement.

Teams with zero remainder against the budget used the full budget efficiently. These typically appear at level 3+ settings where high-tier units all cost enough that four of them exhaust a realistic total. The best farm unit guide covers when to reserve budget for income deliberately versus when to spend it all on immediate DPS.

How upgrade level changes optimizer output

At level 0 the optimizer scores units entirely on placement cost versus base DPS: cheap Rares and Legendaries with fast fire rates often rank higher than expensive Mythics because the DPS-per-gold ratio favours lower cost at zero upgrades. Once you set level 3 or higher, the absolute DPS at level multiplier (1.45× at L3, 1.75× at L5) starts to reward units with higher base damage more strongly, and Mythics pull ahead because their large base numbers scale better through the multiplier.

A practical guideline: use level 0 to 1 when planning a budget starter team, level 3 for a mid-game account that upgrades its carries, and level 5 for endgame roster planning. Running the same stage type at level 0 versus level 5 often produces different teams: not because the units changed, but because the cost-efficiency crossover shifts as upgrades compound.
