Undertale Multiverse Simulator How to Phase in 1.5

Players keep asking “how do you phase” in Undertale Multiverse Simulator 1.5 as if there is a secret input. There is not. A phase is an extra soul-cost entry in the character room. You walk to the kit’s pad cluster, you see Phase 1 / Phase 2 / Phase 3 (or ACT rows) with higher prices, and you buy the row you can afford. That is the whole mechanic.

This page is the shopping explanation. New players should finish the first-hour 1.5 join order before buying phase rows. If you came here because someone told you to press a key, read the PC, mobile, and gamepad bind sheet next: R lowers HP for orange and blue bones. R does not advance a phase.

Phases are prices, not a transformation key

In the Starter Characters Room (white portal, left of lobby) and in the stronger character zone (left and right rooms from about 200,000 souls), some AU kits have more than one pad:

• The first pad is the base form.
• The next pads are phases of that same kit, each with its own soul price.
• Buying a later phase does not refund the earlier one. Budget the row you actually want.

You do not hold a key, you do not drop to 1 HP, and you do not emote. You spend souls. Confirm the number on the pad with the soul unlock tool before you click, because YouTube text from the original place can be stale.

Worked examples (stronger zone)

These prices are the ones the community still uses for 1.5 stronger-zone planning. Recheck the pad if a patch retitles a row.

Kit	Phase rows (souls)
Epic Sans	250,000 / 400,000
Toxin Sans	300,000 / 500,000 / 850,000
Dusttrust Sans	580,000 / 850,000 / 1,000,000

Read that table as a ladder, not as a bundle. Epic Phase 2 is 400,000, not “250k plus 400k unless the pad says otherwise.” Toxin Phase 3 is 850,000. Dusttrust Phase 3 is 1,000,000. If you only have 300,000, Toxin Phase 1 is the honest buy; Toxin Phase 3 is a screenshot.

Other stronger-zone kits also split into phases (Delta, Murder Time Trio, Mirrored Insanity, Ainavol, Venom, and similar). The stronger-zone ranks tell you which ladders are worth climbing. This page will not pretend every row is a must-buy.

Starter-room ladders exist too — Last Breath, Disbelief Papyrus, Fresh, Horror, Killer, TS! Underswap Papyrus, Negatale, and others show extra pads. Treat them the same way: extra price, same room. Names live on the starter roster.

How to buy a phase without wasting the stack

1. Farm with a kit you already own. Follow the soul grind pace and 200k breakpoint so you are not buying phases on a 24-hour empty tank.
2. Walk to the room that actually holds the kit. Starter kits stay behind the white portal. Stronger kits start around 200k in the left/right rooms.
3. Read every pad in the cluster. If you see three Toxin prices, that is three phases, not three different Sanses.
4. Buy the row that matches your soul count and your PvP need. A Phase 1 you can combo beats a Phase 3 you clicked and cannot drive.
5. Leave the room and test the moveset on the 15-player server. If the phase only added flash, you overpaid.

Do not dump early souls into a mid-ladder phase you will replace when the 200k zone opens. Community pace is about 24 hours to the first million and about 20 hours per extra million after that zone. A 400k Epic Phase 2 on day two can be correct. A 850k Toxin Phase 3 before you own a 200k farm kit is usually not.

Phases vs evolutions

Phases share the character room. Evolutions have dedicated rooms. Killer evo and Alpha rooms are the examples players cite, and those doors have swapped in bugs — you click Killer and load Alpha. Scarlet Tenacity, Swapfell Papyrus Phase 2, Hyper Dust (Ruins Dust Sans evo), Fatal Error, and Revenge Papyrus ACT 2 into ACT 3 (2,850,000 souls) are evolution-lane problems, not extra pads in the same starter row. Use evolution rooms and ACT 3 and the evolutions roster for that half.

If a pad says ACT 3, treat the ACT as a named phase/evo with its own price, not as a key combo. You still pay souls.

What not to confuse with phasing

• R / mobile low-HP: HP band for orange and blue bones. Controls.
• Z emote wheel: lobby flex. Not a phase.
• Gamepad X: shiftlock. Not a phase.
• Pesti badge: event clear, then 2,000,000 souls to use him. Pesti Sans event fight. Not a phase row in the starter room.
• Promo codes: we have not verified a public list. Codes will not skip a 850k pad.

When to skip a phase

Skip a phase when:

• You cannot afford the next stronger-zone floor kit.
• You already have a farm kit and the phase does not raise farm speed.
• You are saving for an evolution door or for Pesti’s 2M use-cost.
• You only want the phase because a thumbnail used the Phase 3 skin.

Buy a phase when the base kit is already your main and the next row is a damage or mobility step you felt in PvP. Check starter ranks or stronger-zone ranks before you spend a million on a ladder that the current meta treats as a joke.

Phases are a shop. Walk in with a number, walk out with one pad, and go farm the gap to the next row. That is how you phase in 1.5.
