Reroll Recommendations
The following Reroll Recommendations is thanks to Juliwen#7209 from The Alchemy Stars Unofficial Community Server, all credits to Juliwen, please check out the full Reroll and Progression Guide here.
Take with some salt. Order matters a bit.
Some characters didn’t have their proper stats in the CBT and may be subject to change on release, new characters might be revealed, etc. This was originally gonna be a tier list but then I realized I’m gonna get pitchforked so have some reroll recommendations instead.
Water

The most well-rounded color with a solid foundation. Has the strongest healer orientated character Raphael followed by Philyshy which is helpful for Secret Territory. Raphael and Carleen especially standout as two units that are really stacked in abilities.
Fire

Fire is fairly strong although it is lacking a main healer. Charon and a bit less so Uriel stand out as two units with stacked ability. Victoria is the only consistent way to do healing in Fire (in the CBT) but requires a new unit that applies Bleed status to really shine. Uriel similarly requires Burn status synergy but this is far more common.
Forest

Forest feels the weakest among the colors. Hiiro and Gabriel stands out a bit here. Hiiro is an interesting Converter/DPS and Gabriel has some interesting duo color potential though using her effectively can be hard. The main healer is Uriah a 4* (in the CBT).
Thunder

Thunder overall has some excellent units, though only Irridon and Sorla (who honestly should be a 6 star) have abilities that stand out here. Interestingly Thunder does not have a 2x Combo character, their top choice for healer is Nadine a 4* (in the CBT).

How does the Beginner’s Recruitment work?

The 21st recruit on Beginner’s Recruitment will always be a 6-Star Aurorian from the banner image, even if you have already recruited a 6-Star.
The banner is removed after completing the 21st recruit.
What is the difference between Star Flare and Special Star Flare?
A: Star Flares are only used for Mainstay Recruitment, which does not have any rate-up.
Special Star Flares are used for Time-Limited Recruitment, which have a 50% chance of recruiting the featured Aurorian when recruiting a 6 star.
Time-Limited Recruitment featured Aurorians will be added to the 6-Star pool after their banners end.
How do I acquire Star Flares and Special Star Flares?
A: Lumamber can be exchanged for Star Flares and Special Star Flares at a ratio of 300:1.
Star Flares and Special Star Flares are also available for purchase from various in-game shops, and as rewards for completing certain stages or achievements, among other things.
What are the gacha rates?
A: 2% chance for 6-Star Aurorians, 9.5% chance for 5-Star Aurorians, 33% chance for 4-Star Aurorians, and 55.5% chance for 3-Star Aurorians per recruit.
Time-Limited Recruitment banners have a 50% chance to recruit the featured Aurorian when recruiting a 6-Star.
Is there gacha pity? How does it work?
