Undertale Multiverse Simulator Tier List Hub
S through C for 1.5: farm speed, PvP pressure, and whether the soul price is worth the kit.
This is an opinionated Undertale Multiverse Simulator 1.5 ranking, not a gacha fruit list. Kits move up when they print souls in a 15-player server, win fights, and do not waste a million on a model. Kits move down when they are flavor, prestige, or a worse twin of a cheaper stand. Costs for the stronger rooms prefer PPHS72 1.5 showcases. Starter prices are community-reported from the original wiki and 1.5 reworked attacks, so the same name is not the 2025 kit.
Split lists:
- Starter tier list — white-portal kits, including why Pacifist Sans is called too strong.
- Stronger-zone tier list — left and right rooms, part 2 showcase, skip list versus ceiling kits.
Roster pages with the raw prices: characters hub, starter characters, stronger-zone characters, event characters, character evolutions.
How we grade S through C
Three tests, in order:
- Farm speed — does this kit earn the next unlock faster than sitting on Pacifist?
- PvP pressure — can it contest a 15-player server, not just look loud in a private showcase?
- Soul-cost efficiency — is the jump from the last kit worth the sticker? Dusttrust Phase 3 at 1,000,000 beats Dream at 1,000,000 on this test.
S means you should plan the grind around it. A means it is a real spike or a fair late buy. B means it works if you already own the line. C means collect it after you can farm, or skip it. We do not use D/F; a C kit still functions, it just should not set your route.
This is not official balance. SlayerRealNotFake has not published a tier sheet. Comment sections will disagree, especially on Pacifist. When a patch lands, check version 1.5 before you screenshot this table as law.
S–C overview (September 2026)
| Tier | Kits (short list) | Why |
|---|---|---|
| S | Pacifist Sans; Dusttrust Phase 3; Error; Ink line (Ink / Emotionless / Shanghaivania); HyperDust Ink; Murder Time Trio Phase 3; Divine DustDust; ACT 3; Pesti Sans; Obsessed Monster | Either free-and-broken (Pacifist) or the kits showcases actually linger on. High PvP pressure. Event S kits still need badges or 2M+ souls. |
| A | Photonegative; Epic Phase 2; Toxin Phase 3; Last Breath; Ruins Dust (as a Hyper Dust door); Cross; DustDust; Virus / Anti-Virus; Nightmare; Hyper Revert Dust; Fatal Error (evo, live price unconfirmed) | First stronger-room spikes, or late kits that win fights without being the ceiling. |
| B | Epic Phase 1; Toxin Phase 1–2; SwapDust Papyrus; Sudden Change; Delta; Dustfell; OuterDust; Fazy Swap Papyrus; Color / OtherTale; Dustbelief; Bad Time Trio; Ainavol; Molten Lava; Killer; Geno; Insanity; Storyshift | Usable, often on the way to an S/A kit. Fine to own, bad as a destination. |
| C | Science; Underfell; Outertale; Swapswap; Negative; Hardtale; Fresh; Horror; Nega; Dream (at 1M next to Dusttrust P3) | Flavor, prestige, or a worse twin. Buy when you are collecting, not climbing. |
Scarlet Tenacity P1–P3 and Swapfell Papyrus Phase 2 stay unranked until a public 1.5 cost exists. Hyper Dust Sans is a Ruins Dust evolution — treat the base kit as A for the door, not as an automatic S. The original-game NULL zone (10,666,666) is not on this list because we do not claim it exists in 1.5.
Early, mid, high
Early is the white portal. Only kits that can farm belong on a route: Pacifist, maybe Underswap, then Last Breath or Ruins Dust. The rest of the starter roster is a museum. Details: starter tier list.
Mid is the first stronger-room hour: Photonegative at 200,000, Epic, Toxin. Fazy Swap Papyrus is the right-room twin of that door. You should feel the account get faster here. If you do not, you bought Storyshift or Fresh instead of Photonegative.
High is everything the mid-article video actually spends time on: Dusttrust P3, Error, the Ink line, HyperDust Ink, Murder Time Trio P3, Divine DustDust, ACT 3, plus event kits Pesti and Obsessed Monster. Those are S because they are the kits people still clip, not because a gacha banner said so.
How to use this hub
- Pick a farm kit from the starter tier list. Pacifist is the honest answer for most accounts.
- Follow the soul grinding route until 200,000. Confirm prices in the soul unlock tool.
- Buy Photonegative, then one of Epic / Toxin. Raw tables: stronger-zone characters.
- Choose one high line (Dusttrust, Ink, or ACT) using the stronger-zone tier list. Do not start three million-soul lines at once.
- Add event characters only after you understand the Pesti Sans fight. Badge plus souls, not souls alone.
- Touch evolutions when the pad is visible. Scarlet Tenacity remains cost unknown.
Promo codes do not change tiers. If one appears, it goes on codes. Scripts do not belong in a ranking — see scripts for the risk note, not for a farm shortcut. New accounts still start at getting started and controls.
S is for kits that change the account. C is for kits you buy because you like the AU. If a name is missing from the overview table, it is either unranked (no public 1.5 cost) or it belongs on a child page. Use the two child lists for the argument; use this hub only to decide whether you are still in the white portal, the 200,000 rooms, or the two-million ceiling.
Frequently Asked Questions
Quick answers to the most common questions.
Is this an official 1.5 tier list?
No. It is this wiki's ranking by farm speed, PvP pressure, and cost efficiency. Patch context is on version 1.5.
Why is Pacifist Sans in S with ACT 3?
Different jobs. Pacifist is free and players call it too strong. ACT 3 is a 2.85 million ceiling kit. Early ranks are on the starter tier list.
Where are the stronger-room ranks?
On the stronger-zone tier list, with part 2 of the zone showcase. Raw prices stay on stronger-zone characters.
Do event kits count?
Pesti and Obsessed Monster are S on cost-to-pressure once you can pay. Badge rules are on event characters and the Pesti Sans guide.
Should I follow this order on a fresh account?
Yes for the early/mid split: Pacifist, then Photonegative. Walkthroughs are getting started and the grind route.
