Best Kirito (Kriatu Cheater) Build in Universal Tower Defense X

The exact trait, relic pieces, and stat priority that push Kirito's crit damage in Update 3.0.

The exact trait, relic pieces, and stat priority that push Kirito’s crit damage in Update 3.0.

Kirito appears in Universal Tower Defense X as the Mythic unit Kriatu (Cheater), and the unit leans hard into critical hits. The strongest setup focuses on crit damage scaling backed by a low cooldown, so the unit fires often and lands heavy crits each time. Below is the precise build to run, the relic perks behind it, and how to confirm it is working.

Quick answer: Run Kriatu (Cheater) with the Duelist trait, put stat points into Cooldown, and equip Sun God on the head with Elemental Damage, Ex Capt. Uraharo on the body with Critical Damage, and Ex Capt. Uraharo on the legs with Damage.

Why Duelist and Cooldown fit Kirito

Duelist is the recommended trait for Kriatu (Cheater) because the unit’s damage comes from frequent, crit-driven hits rather than stacked damage-over-time. Traits like Astral favor units with many DoT stacks and low cooldown, while Ruler suits units with one or two placements. Kirito sits outside both of those profiles, so Duelist is the better match.

For stat points, Cooldown is the pick. Percentage gains across stats are fairly even, so reducing cooldown gives more attacks per second and more chances to crit. That keeps the crit-focused relic perks active more often.


Ex Captain and Sun God relic perks

Two Ex Capt. Uraharo pieces give the Ex Captain set bonus, which is built for crit. The head uses a Sun God piece purely for its Elemental Damage main stat, so the build mixes a crit core with extra elemental scaling.

SetTop + Bottom perkAccessory perk
Ex Captain+10% Critical Rate, +25% Critical DamageRefunds 5% of yen spent on upgrades
Sun God+5% Damage, +10% Light, Water, Ice DamageEvery 6 attacks, damage buff equal to range (1 range = 1% damage) for 7 seconds

The Ex Captain crit rate and crit damage stack with the body slot’s Critical Damage main stat, which feeds the unit’s crit-based passive. The legs slot’s flat Damage rounds out raw output.


Relic main stat caps to aim for

Mythic relics reach max level 15 with up to five substats. Hit these caps on the matching slots so the build performs at full strength.

SlotStatCap (Lv.15)
Top (Body)Crit Damage+120%
Top (Body)Damage+60%
Bottom (Legs)Damage+60%
Bottom (Legs)Cooldown-22.5%
Accessory (Head)Elemental Damage+30%

Keep clean main stats before chasing perfect set effects. For substats, prioritize crit rate, crit damage, and damage so every hit benefits from the crit core.


Exclusive relics and how they work

Character-exclusive relics are tied to specific units rather than the standard sets, and they carry strong stat buffs. Kirito’s optimal setup does not use one of these, but it helps to know what exists and where it drops if you build around other units later.

How to confirm the build is active

Open the unit’s loadout and check that Duelist is the equipped trait. If it shows a different trait, reroll or swap before deploying.
Confirm two Ex Capt. Uraharo pieces are slotted on the body and legs so the set perk reads +10% Critical Rate and +25% Critical Damage. The bonus only applies when both matching pieces are equipped.
Place the unit in a match and watch the damage numbers. Frequent yellow or highlighted crit numbers mean the crit scaling is firing as intended, and the cooldown stat will show shorter gaps between attacks.

Relic rerolling sits behind the evolution NPC, and locking a stat adds one Relic Reroll cost per roll. If your crit damage feels low, level the body relic to its +120% cap first, then refine substats toward crit rate and crit damage to keep Kirito hitting hard across Nightmare, Infinite, and Virtual Realm runs.
