You might be wondering...
What is this Tier List?
This tier list aims to be the most comprehensive written tier list for Alchemy Stars available on the English-speaking internet. AncientSpark originally created the sheet, but eventually became too busy to frequently update it. Fourmana offered to help reformat the original tier list and update all the past event units that Spark wasn't able to get to, and has been keeping it up-to-date ever since with the help of members of the official Alchemy Stars Discord. We believe our methodology (elaborated below) in tandem with some absolutely mind-numbing math have gone a long way toward creating the first resource written in English that adequately tiers all units. Of course, not everything is perfect - but we're always open to feedback. We think this is a great guide for new and veteran players alike, and hope the time invested here will go a long way towards growing this incredible game.
How do I read this list?
The "General Tier List" is the page which you can use to determine a unit's general rating by the community at a glance, as well as get an idea of what each element looks like at the top and bottom end of the spectrum. This is also the least technically accurate page; for example, Hydrad and Philyshy are both "S-tier Flex Slot," but they do radically different things.
On the General Tier List, we assume Max Breakthrough ("MBT") for all 3 stars, 4 stars, and Event Welfare 5 stars, and assume Breakthrough 0 (BT0) for all five stars and six stars unless otherwise stated in the unit's icon. This is because 3 stars, 4 stars, and welfare 5 stars take minimal time to MBT, whereas gacha five and six star units can take months to get past BT0 if you're unlucky. We also mark units that are slightly above or below the rest of their tier with a "+" or "-" in the Unit Icon. Take note -- for example, five star Areia is S+ (indicated by her icon), which places her above all her six star forest DPS competition in most scenarios. The "Element Pages" is where you'll find the actual meat of our analysis and tips for any given unit. On these pages, we include name and icon as with before, but list not only their overall rating, but their individual class rating (i.e. what they do and how good they are at it), some pros and cons, and a detailed write-up about their kit, and what they specifically excel at. We recommend you refer to the Element Pages for your units before you make a decision about who you want to raise, what account you want to keep, etc., etc. Tier lists are fallible precisely because they generalize, and the Element pages are our way of trying to fix that. If you see Bold on an Element Page, it's because it's something that makes the unit absolutely insane (i.e. SS tier, or close to it).
How do we tier?
This tier list works by comparing units not only within class but also within the slot they compete for. Teams in Alchemy Stars are designed to be mono-element (or mono-element with an off-element captain) and are usually comprised of the following:
2 DPS: Two units dedicated to just pumping out damage, usually occupying the first and fifth slot. Within this role, Detonators (AOE damage) and Snipers (single-tile damage) compete with one another. However, Detonators are almost always better, due to the exponential nature of multi-tile damage, and the fact that there is little in the way of challenging single-tile content. 2 Converters: Converters are the absolute backbone of this game and it isn’t a stretch to say that you really can’t play the game without them. It is strongly suggested that you start the game with the element that you have at least 2 S-tier converters for. We seriously can not emphasize their importance enough — if this list compared units across slots, even the S-tier converters would be SS. 1 Flex Unit: Your final member of the team (usually occupying the fourth position) is basically whatever you want it to be, whether that’s another DPS, another converter, or a dedicated support unit which really only belongs in the flex slot. This varies from stage to stage and also faces the stiffest competition; for this reason, dedicated flex slot units like double chainers, healers, and sub-DPS units are rated lower on the whole, despite the fact that they all have individual stages where they can be absolutely necessary. NOTE: Support Units primarily prefer the Flex Slot, but they are absolutely not limited to them. Support Units can often fall into the other slots if you want them to; for example, some people use the BT3 Reset Angels as dedicated converters, or the 2x Chainers as their 2nd DPS. Make sure you read their kit, as a unit like Florine is actually better as a DPS than a dedicated DPS that's just bad. With this in mind, we evaluate units first based on a unit’s performance within its class (Detonator, Sniper, Converter, Support, Etc.), and list that rating within the individual element chart. From there, we look at what it’s competing with in slot (DPS, Conversion, Flex), and decide how powerful the unit is in the context of teambuilding. Because of this, overall tier ranking is not everything. There are many instances of high tier units being utterly terrible for specific situations (such as DoT characters in late Spire and Endgame), while certain units that have extremely strong yet specialized classes (resetters, teleporters, etc) can suddenly become very powerful in specific situations (pre-nerf Alice in Endgame, ways to cheese Sol Morph movement on F89). ALL COMPARISONS WITHIN ROLE ARE MATHEMATIC APPROXIMATIONS, NOT LITERAL EQUIVOCACIES. IF YOU HAVE AN ISSUE WITH OUR MATH OR TESTING, LET US KNOW!
How do we define class rating and slot?
1. How often does this class address a necessary niche?
2. Can another class address this niche with something else? (i.e., teleporting vs conversion, or out-DPSing maps that would normally want healing) 3. Is this class self-sufficient? (i.e., resetters often needs other converters to help them) 4. How much competition does this class face in its slot?
What are "T" and "N" ratings?
T ratings denote units that enable or become significantly stronger in dedicated teams. Usually these teams rank at the top of their respective elements, and they’re worth mentioning. N ratings are ratings that showcases units that are a lot stronger in a specific niche than anywhere else.
How do we handle refinements?
For the sake of clarity, we display the refinement grades as we always assume max investment outside of breakthroughs. However, we do note when there a gulf between non-refinement performance and refinement performance in the units descriptions.
The majority of credit goes to AncientSpark, who originally put together the original tierlist and kept it updated throught the release of Gram and Revy. The original tiering system, ranking philosophy, and a good third of the write-ups were done by him, and we don't think this spreadsheet could have ever been done without his initial dedication. Another person thats worth mentioning is Fourmana, who spearheaded this fork of AncientSpark's work, and was the previous leader of Team BethelFrankel.
Currently, the sheet is maintained by Team BethelFrankel, a premier group of players who operate this sheet part-time. We update it with each release cycle. Cuzimori is the current team lead, and he handles most of the formatting and the writing for the Tier List. AlanaEclogia is vice leader, and she handles communication between other servers. Raf and Alpaca are the primary playtesters. Bless is the editor for the write ups. Retired team-members Reanimu, AceZero, Neppity, Kuro, Boop, Ivory, Trakan, Mechahydra, and Defeatable were invaluable in getting the Tier List to where it is today. Finally, DK, Nicklas, Ureki, Vyse, Raf, TheGrandWarlock, Kashira, S67 and many more from our thread on the official Discord and our own server have contributed significantly in our discussions! -Fourmana
Current status of updates
We are currently up to date, with the caveat that our ratings for the new units are still subject to change with more testing. New reviews are released about a week after each new banner.
