- Undertale Adventures X tier list: Units ranked S through D by damage, range, support value, and acquisition difficulty.
- Context matters: Early progression favors accessible units; late-game rewards scaling and coverage.
- Best strategy: Build a balanced core of damage, support, and economy units before investing in duplicates.
- Solo vs. team: Solo teams need self-sufficient units; team play allows specialized roles.
- Reassess often: Balance updates can shift unit value after every major version change.
How This Undertale Adventures X Tier List Works
A useful tier list reflects the situation in which a unit is used, not just raw stats. This ranking evaluates units across five criteria: sustained damage output, attack range and coverage, support and utility value, acquisition difficulty, and consistency across game modes including Story stages, Raids, Gauntlet, and farming runs.
Early progression favors accessible, reliable units that can clear Ruins and Snowdin stages without heavy investment. Later content in Hotland and Core rewards stronger scaling, wider coverage, and specialized support effects. A unit that carries early stages may drop to C Tier once stronger options become available, and that is expected.
| Criterion | Weight | What We Measure |
|---|---|---|
| Sustained output | High | Damage per wave, boss damage, upgrade scaling |
| Range and coverage | High | Path coverage, multi-target patterns, placement flexibility |
| Support value | Medium | Buffs, debuffs, crowd control, team utility |
| Acquisition difficulty | Medium | Summon cost, shard investment, progression gating |
| Mode flexibility | Medium | Performance in Story, Raids, Gauntlet, and farming |
No single ranking fits every player. A B Tier unit with strong area coverage can outperform an S Tier single-target unit on dense enemy waves. Always match unit choices to the stage layout and your current roster gaps before spending upgrade resources.
Tier Rankings: S to D
The full ranking splits units into five tiers based on overall account value. Because specific unit statistics change with balance updates, this table focuses on the role profile that defines each tier so you can classify any unit you own.
| Tier | Category | Best For | Key Evaluation Points |
|---|---|---|---|
| S Tier | Late-Game Priority | Difficult stages, long runs, organized team play | High sustained output, useful range, strong scaling after upgrades |
| A Tier | Reliable Core | General progression, solo play, mixed difficulty | Good performance for investment, straightforward deployment value |
| B Tier | Situational Value | Specific enemy layouts, alternative builds | Stage-dependent performance, placement-sensitive patterns |
| C Tier | Early or Specialized Use | Starter rosters, low-difficulty stages | Limited scaling, narrow application, replaced over time |
| D Tier | Filler Units | Collection goals, emergency slots | Minimal impact, low upgrade efficiency |
S Tier Profile
- Strong scaling into late content
- Dependable path coverage
- Valuable support or control effects
- Core of most endgame teams
A Tier Profile
- Consistent performance across stage types
- Solid return on upgrade investment
- Forms the backbone of progression teams
- Effective in solo play
B Tier Profile
- Stage-dependent effectiveness
- Shines with the right placement
- Useful as a flex pick
- Moderate upgrade efficiency
Before judging a unit's tier, test it in the mode where you actually use it. A unit that underperforms in Story stages may excel in Raids or Gauntlet due to different enemy pacing and wave density.
Tier Ratings by Game Mode
Unit value shifts significantly between modes. The table below summarizes which tier profiles perform best in each activity type so you can allocate upgrade resources efficiently.
| Mode | Best Tier Profiles | Recommended Focus | Primary Reward Type |
|---|---|---|---|
| Story stages | A Tier core plus one S Tier damage unit | Balanced damage, coverage, and early economy | Progression access, stage rewards |
| Raids | S Tier scaling units with support backup | Boss damage and sustained output | Raid-specific rewards |
| Gauntlet | S and A Tier wave-clear units | Area coverage and multi-target damage | Challenge rewards |
| Farming runs | Fastest reliable A Tier team with economy unit | Clear speed over theoretical damage | Currency and upgrade materials |
| AFK Chamber | Economy and low-maintenance units | Set-and-forget coverage | Passive resource generation |
Solo teams should prioritize self-sufficient damage and full-path coverage because no teammate will fill missing roles. In team play, specialized units gain value when they fill a gap, such as dedicated crowd control or boss damage, that other players are not covering.
Step-by-Step: Building a Team From the Tier List
Follow this sequence to turn tier rankings into a working team without wasting resources on low-value investments.
Identify Your Roster Gaps
Check whether your current team is missing a reliable damage dealer, a support or control unit, or an economy unit for early upgrades. Summon with a clear role in mind rather than pulling repeatedly without a team-building goal.
Secure a Core Progression Team
Use early resources on A Tier units that help clear main stages and unlock more content. Favor units that provide immediate account value over duplicates that do not change your progression.
Upgrade Damage Sources First
Spend stage income on your most active damage dealers before improving low-impact units. Compare upgrade costs against the immediate benefit each level provides.
Add Support and Coverage
Once core damage is stable, add support, control, or area-coverage units that handle the enemy layouts where your damage units struggle.
Invest in S Tier Late-Game Units
After establishing a stable farming team, invest in S Tier scaling units and improve traits on units that remain useful across multiple modes.
Treat shards and soul-type resources as limited progression currency until your account has a stable farming team. Compare the value of a guaranteed targeted acquisition against several low-priority random pulls before spending.
Traits, Updates, and Tier Shifts
Traits directly affect where a unit lands on any tier list. A damage unit with an offensive trait can effectively perform a tier higher, while a mismatched economy trait on a boss damage unit weakens its ranking. Before using a trait reset, compare the current trait with the unit's placement, upgrade cost, and role in your main team.
| Unit Role | Preferred Trait Direction | Keep When | Reset When |
|---|---|---|---|
| Output units | Damage, attack speed, range | Trait strengthens main damage role | Trait only boosts economy or support functions |
| Support units | Effect reliability, uptime, range | Trait extends buffs, debuffs, or control | Trait only adds personal damage |
| Economy units | Income and early contribution | Unit is used at stage start for income | Unit is retired from farming rotations |
Balance updates also reshape the meta. New units can change summon priorities, trait adjustments can affect reset plans, and performance changes can alter the best farming team. Review the official Roblox game page and the Side Productions community for the latest patch information.
Recheck your main damage, support, economy, and farming teams after each major version change. A previously weak unit can become more useful, and a prioritized trait can lose value. Test changed units in the modes where you actually use them before committing reset resources.
Team-Building Milestones:
- Establish one A Tier core damage unit
- Add area coverage for dense waves
- Include an economy unit for early upgrades
- Secure one S Tier scaling unit for late content
- Match traits to each unit's primary role
FAQ
Q: What is the best tier in the Undertale Adventures X tier list?
S Tier represents late-game priority units with strong scaling, dependable coverage, or valuable support effects. They perform best in difficult stages, longer runs, and organized team play, but A Tier units often offer better value early in progression.
Q: Should I only use S Tier units?
No. A Tier units form the reliable core of most progression teams and often outperform S Tier units for the investment required. B Tier units can also exceed expectations when their attack pattern matches a specific stage layout.
Q: How does solo play change tier rankings?
Solo teams should prioritize self-sufficient damage and full-path coverage since no teammates will fill missing roles. In team play, specialized units gain value by covering roles such as crowd control or boss damage that other players leave open.
Q: Do balance updates change the tier list?
Yes. New units, trait adjustments, and balance changes can shift unit value after every major version. Reassess your damage, support, economy, and farming teams after each update and test changed units before spending reset resources.
