Re://Adventures Progression Guide: Early to End-Game Route

Quick answer

Clear story mode until all unit slots are unlocked, then evolve your units, then move into the infinite-mode token grind.

• Story comes first: clear it until all slots are open.
• Next, evolve units using stars earned from area challenges.
• After that, the repeatable loop is infinite mode for tokens used at the spin NPC.

Where progression starts: clear story to unlock all slots

After the initial summon, the first progression goal is to complete story mode until all unit slots are unlocked. A creator walkthrough puts it simply: you want to just complete the story mode till you unlock all the slots.

The relaunch version only has a limited number of story stages available, so this phase is relatively short. One overview notes there are only four story stages up to Sand Village, and describes the available content as essentially just story at that point. Other playthroughs reference progressing through acts up to act six and mention maps such as Snowy Town, Wald City, and Sand Village, so the exact stage and act structure can look different depending on when you are playing. Check your own stage list in-game rather than assuming a fixed count.

Early priorities: codes and story acts for resources

Before or alongside early story progress, redeeming codes provides a large early resource boost. A playthrough states the first thing to do is go ahead and redeem some codes, and reports receiving 15.5,000 gems, 178 star remnants, and perfect stat cubes from codes.

Story acts also serve as a gem source during the early route. Another playthrough notes finishing story acts just to get a little bit of gems, and mentions that reaching act five opens access to the daily challenge.

First major milestone after story: evolve units with stars from area challenges

Once story is done, the next milestone is evolving units. A creator guide says that once you're done with the storyboard you should try to evolve your character, and advises crafting and evolving all units you can.

Stars needed for evolution come from area challenges: to get the stars you just go to area challenges and then try to beat the stages. Another overview confirms challenges are central to evolution, saying the only way to evolve is just to do challenges, and notes that a player may need to wait for challenges to refresh between attempts.

End-game repeatable activity: infinite mode for tokens and spins

After evolving units, the creator describes the player as being at the end-game stage with little remaining content, and the recommended repeatable activity is to grind infinite mode and collect tokens for the NPC spin. The guide states that after you evolve your units you're basically at the end-game stage, and then you should just grind infinite mode and try to get the token for the NPC.

A separate reroll-focused source confirms the token source: do infinite mode for 15 waves and you get one token, which can then be used at the spin NPC.
