Anime Astral Simulator Vessel: Branch and Token Guide
Learn which Anime Astral Simulator Vessel branch to activate, how Vessel Tokens level it in Leaf Defense, and where Research Data fits into your build.
Anime Astral Simulator Vessel: What to Activate
The Anime Astral Simulator Vessel system offers two choices in World 18: activate the Power and Attack Speed branch for power farming, or the Damage, Critical Chance, and Critical Damage branch for combat output. To level an Anime Astral Simulator Vessel, select it before running Leaf Defense; Update 14.5 player footage shows Vessel Tokens being applied to the active choice. Research Data comes from the same mode, but it upgrades Scientific Modifications instead of Vessels.
This guide is based on community gameplay recorded around Update 14.5, not official patch notes. The official Anime Astral Simulator Roblox page identifies the experience and displays the Vessel update label, but it does not document the mechanic's detailed rules.
How the Vessel System Works
The Vessel interface was shown in World 18 with two selectable options. One increases Power and Attack Speed, while the other increases Damage, Critical Chance, and Critical Damage. Community footage also demonstrates switching from the first Vessel to the second after earning levels, so the initial activation does not appear to be a permanent account-wide choice (Update 14.5 gameplay at 11:59).
The auto-generated transcripts render the character names inconsistently. To avoid presenting corrupted names as fact, this guide uses functional labels: Power Vessel and Damage Vessel.
| Vessel branch | Stats shown in footage | Practical purpose |
|---|---|---|
| Power Vessel | Power and Attack Speed | Building power more quickly through faster attacks |
| Damage Vessel | Damage, Critical Chance, and Critical Damage | Improving direct damage and critical-hit output |
These are parallel progression options, not an official tier list. The better Anime Astral Simulator Vessel depends on what is limiting your current build.
Power Vessel
Choose the Power Vessel when your immediate goal is accumulating power. Update footage describes Attack Speed as making attacks or clicks occur faster, while another player report explains that each hit generates power. Together, those mechanics make Attack Speed a natural companion to the branch's direct Power bonus (system overview at 7:40).
This branch is the clearer first choice when you are:
- Concentrating on power progression
- Spending a long session in Leaf Defense
- Trying to increase the number of power-generating attacks
- Not currently blocked by an enemy's health or a timed damage check
That recommendation is an interpretation of the displayed stats, not an official declaration that the Power Vessel is universally best.
Damage Vessel
Choose the Damage Vessel when combat output is the immediate problem. Its displayed bonuses affect base Damage, Critical Chance, and Critical Damage, giving it three stats tied directly to offensive performance (Vessel comparison at 7:44).
It is the more relevant branch when:
- An exam or other encounter survives your current attacks
- You are preparing a dedicated damage build
- Critical-hit output matters more than power generation
- Your power progression is already adequate for the activity you want to attempt
No supplied source establishes an exact damage requirement for an exam, a guaranteed clear point, or a competitive Vessel ranking. Treat the branch as one part of a complete damage setup.
How to Level an Anime Astral Simulator Vessel
Community Update 14.5 footage connects Vessel progression to Leaf Defense. The interface reportedly states that Vessel Tokens are added to Vessels when obtained, while the player can select which Vessel receives progression (World 18 Vessel interface at 2:18).
A practical leveling route is:
| Step | Action | Why it matters |
|---|---|---|
| 1 | Open the Vessel interface in World 18 | This is where the two branches were shown |
| 2 | Activate the branch matching your current goal | Footage indicates the selected Vessel is the one that levels |
| 3 | Enter Leaf Defense | Community reports identify this mode as the Vessel Token source |
| 4 | Continue through waves you can clear reliably | Tokens and Vessel levels were observed during Defense runs |
| 5 | Check the Vessel interface after the run | Confirm that the intended branch received progress |
| 6 | Switch branches before another run if your priority changes | Gameplay shows a player moving from Power to Damage progression |
The sources do not verify a fixed number of Vessel Tokens per wave, a guaranteed token rate, or a complete drop formula. One recording showed tokens appearing early in a run, but that single result should not be treated as a universal farming guarantee (Leaf Defense run at 4:47).
Before committing to a long session, verify that the desired Vessel is active. The supplied footage does not show a way to transfer previously earned levels from one branch to the other.
What Leveling Looks Like
The Vessel's displayed bonuses rise with its level. In one player account, the Power Vessel had reached level 25 and displayed almost 500% additional Power plus nearly 10% Attack Speed. Later in the same recording, the Damage Vessel reached level 30 with almost 300% Damage, 3% Critical Chance, and nearly 30% Critical Damage (Power example at 11:47; Damage example at 17:09).
Those figures are account snapshots observed in community footage collected September 19, 2026. They are useful examples of how the branches scale, but they are not promised values for every version, and the supplied evidence does not establish the Vessel level cap.
Vessel Tokens vs. Research Data
Leaf Defense supports more than one Update 14.5 system, which makes its rewards easy to confuse. Vessel Tokens and Research Data come from the same activity but serve different upgrade tracks.
| Resource | Used for | Where community footage found it | Does it level a Vessel? |
|---|---|---|---|
| Vessel Tokens | Progressing the selected Vessel | Leaf Defense | Yes |
| Research Data | Buying Scientific Modification levels | Leaf Defense | No |
| Young-Tailed-Beast gacha currency | Rolling the corresponding gacha | Leaf Defense footage showed this currency in the mode | No |
The Scientific Modifications interface contains five permanent upgrade categories in the observed version. Community footage describes bonuses covering Power, Yen, Damage, Critical Chance, and Drops, with up to 50 levels shown for each modification (Update overview at 0:06).
Research Data should therefore be spent according to a separate build decision. Investing it in a Power modification does not replace activating or leveling the Power Vessel. Likewise, upgrading Damage or Critical Chance through Scientific Modifications does not add levels to the Damage Vessel.
A simple way to keep the systems straight is:
- Select a Vessel before farming: determines which Vessel branch receives progression.
- Collect Vessel Tokens: advances that selected Vessel.
- Collect Research Data: remains available for Scientific Modifications.
- Spend Research Data manually: choose the permanent stat category that supports your build.
- Review both systems separately: a strong Vessel does not mean your Scientific Modifications are upgraded, or vice versa.
One community recording noted that Research Data did not appear clearly in the mode's displayed information even though the account received it during the run. Players should check the Scientific Modifications interface or their available resource total rather than relying only on the visible Defense reward list (Leaf Defense observation at 10:18).
Which Vessel Should You Level First?
For a general progression session, the Power Vessel is the more directly aligned starting branch because it combines a Power increase with faster attacks. That conclusion follows from the displayed stat combination; it is not an official best-in-slot ruling.
Switch to the Damage Vessel when a specific fight, exam, or mode is limited by damage rather than power growth. In the supplied footage, players deliberately changed to damage-focused setups before combat attempts, but their individual results do not establish a universal threshold.
| Current problem | Suggested active Vessel | Reason |
|---|---|---|
| Power is growing too slowly | Power Vessel | Both displayed bonuses support power generation |
| You need more attacks over the same period | Power Vessel | Attack Speed was described as increasing click or attack frequency |
| Enemies survive your current damage | Damage Vessel | It directly raises Damage and critical stats |
| You are preparing a critical-focused build | Damage Vessel | It includes Critical Chance and Critical Damage |
| You are only farming Research Data | Either, based on secondary goals | Research Data upgrades a separate system, while the active Vessel can still gain progress |
The efficient choice is goal-based rather than permanent. Activate the branch that helps the activity you are doing now, verify that it is selected, and use Leaf Defense to progress it. Change to the other Anime Astral Simulator Vessel when your bottleneck shifts.
Because the supplied evidence consists mainly of player recordings, several details remain unverified: exact token rates, the full leveling formula, the maximum Vessel level, and whether later updates alter the stat curves. Check the in-game interface before making decisions based on any numerical example.
Anime Astral Simulator Vessel FAQ
Where is the Vessel interface?
Update 14.5 community footage shows the Vessel system in World 18. The sources do not provide a verified prerequisite beyond reaching and accessing the relevant area, so this guide does not claim a separate unlock requirement.
How do I get Vessel Tokens?
Run Leaf Defense with your intended Vessel selected. Multiple community recordings identify Leaf Defense as the source and show Vessel levels increasing during Defense farming (player report at 2:24). No exact per-wave rate is confirmed.
Are Vessel Tokens and Research Data the same thing?
No. Vessel Tokens progress the active Anime Astral Simulator Vessel, while Research Data buys levels in the separate Scientific Modifications system. Both were observed as Leaf Defense rewards, but they are not interchangeable.
Can I change from the Power Vessel to the Damage Vessel?
Yes, Update 14.5 footage shows a player leveling the Power branch and then activating the Damage branch for another Leaf Defense session. The evidence supports switching between them, although it does not document every possible restriction or interface condition.
