How to get Cubert

  1. Inspect the current Tower season's Floor 50 reward before committing to the climb. The published route is a season milestone, not a banner pull.
  2. If Cubert is listed, clear the relevant Floor 50 track and claim its reward. The guide suggests normal/Trait Tower first; Traitless is a separate harder track, not a shortcut.
  3. The reviewed records list no Cubert evolution. Confirm the owned unit's current panel before farming a purported evolution item or spending rerolls.

This is a published seasonal route, not confirmation that Cubert remains obtainable in the current Tower season. No verified end date or alternate current acquisition route is established here.

September 2026 publisher assessment

PGG's September 8 assessment places Cubert in A tier as a support specialist. Judge the carry's improvement and control uptime, not only Cubert's own damage or a universal best-team label.

Safe decision

Build it when these jobs solve a real team gap. Test the complete setup before spending rare rerolls or replacing a proven slot.

Kit interpretation

What Cubert does

Cube Link buffs attached allies, with additive bonuses when cubes overlap in range. Regular attacks from the attached ally build Cube Overload toward a damage-and-Stun explosion. Cube charges regenerate over time; placement and ally attack frequency determine the practical coverage.

These are mechanical roles, not a promise that the unit wins every map. Placement, upgrades, target type, allies and stage duration can change the outcome.

Reroll stop rule

Trait direction

PGG favors Primordial for support coverage. Its assessment says Unbound reduces three placements and a six-cube ceiling to one placement and two cubes: compare team benefit before trading coverage for personal damage.

Use the trait odds calculator before committing crystals. A mechanically relevant owned trait can be better account value than chasing a rarer headline trait.

Evolution and equipment checks

No reviewed evolution recipe in the current table

The acquisition report above does not establish a complete evolution recipe. If the live client offers an evolution for your copy, confirm its target form and every material there; no missing recipe is counted as free.

No unit-specific match in the reviewed equipment table

Do not assume that absence means “no equipment.” It only means the current source catalog has no named exclusive record matched to this unit. Compare live rolls by bottleneck.

Original field protocol

How to test Cubert on your account

  1. 1. Freeze the conditions

    Use the same stage, act, party, upgrade, placement, trait and equipment. Record the game date or visible version.

  2. 2. Measure the kit's real job

    Keep the carry, upgrades and map fixed. Compare overlapping versus separated cube placement, record buff uptime and Stun cycles, and compare the resulting clear with the support unit you would replace. A faster clear is a test outcome, not promised by this guide.

  3. 3. Keep outcomes separate

    Record personal output, team effect, control, economy and clear consistency as separate fields. One blended score hides why a unit worked.

  4. 4. Repeat and label the sample

    Start with at least 10 matched runs when practical, publish the exact count and retain failures. A small sample is useful when it is honestly labeled.

Sources, confidence and deliberate omissions

The historical July labels and role scopes stay visible on the five-source tier matrix. Where a dated Wiki table is available above, its level and equipment conditions are explicit. Other unsupported base stats, placement costs, banner odds and universal DPS remain omitted. The live client is stronger evidence for your current version. If a cited mechanic changes, send the page URL, screenshot or official note through the correction channel.

Cubert quick questions

What role does Cubert play?

The documented profile supports Support, Control, Summon jobs and uses a Magical damage classification. The best role depends on which part of the kit your stage and team can activate.

What trait should I use on Cubert?

PGG favors Primordial for support coverage. Its assessment says Unbound reduces three placements and a six-cube ceiling to one placement and two cubes: compare team benefit before trading coverage for personal damage. Treat this as a direction and stop rule, not a guarantee that one rare trait is optimal for every account.

Is Cubert top tier?

PGG's September 8 assessment places Cubert in A tier as a support specialist. Judge the carry's improvement and control uptime, not only Cubert's own damage or a universal best-team label. Rankings are dated judgments; matched tests and current balance notes should decide expensive investment.
