Potions are Anime Astral Simulator’s most mismanaged resource — handed out by the dozen through codes, then burned at the wrong moments because the game never explains them. Here’s the full taxonomy, the sourcing, and the timing rules. Honesty first: the developer publishes no boost percentages or durations for any potion, so this guide is about when and which, not imaginary numbers. Community-reported throughout — verify in-game.
The six types and what they touch
- XP Potion — levels you faster (cap 75 since Update 1). Front-load these: early levels gate stat points when they matter most.
- Power Potion — boosts the stat that gates quest chains and rank-ups; the progression potion.
- Damage Potion — boosts damage output for boss walls and gate runs.
- Yen Potion — more Yen per kill; Yen feeds the Star gacha, so this is really a summons potion (the pity math it accelerates is in how summoning works).
- Drop Potion — better item drops; the boss-farming potion.
- Luck Potion — the contested one, covered below.
Each comes in Tier I and Tier II (codes deliver both; 15KPLAYERS notably paid all Tier II), and there’s a use-all button for people who’d rather not optimize. Durations tick while you play.
The Luck potion question
Luck is the potion everyone hoards for summon sessions, and the evidence it works there is genuinely murky: the developer’s own Trello FAQ states each gacha “uses its own luck” and that external drop percentages don’t affect it — which reads like Luck potions touching world drops but not Star odds. Community testing is mixed, and one widely-copied claim about Luck II multiplying Divine rates traces to a site we’ve found unreliable, so we don’t repeat its numbers. Our advice: treat Luck as a drop-farming potion (pair with Drop on boss runs), and if you want to test it on summons, compare a small batch with and without before betting a pity run on it.
Where potions come from
- Codes — the motherlode: roughly 150 potions across the 36 active codes, alongside ~6,300 tickets. Every compensation code carries a potion bundle.
- Daily chests — a steady trickle; open one every session.
- The Trial Shop (Tier I) and Defense Shop (Tier II) — both got official price cuts in the QoL update, making Trials and Titan Defense the renewable sources.
- Store bundles — the Robux route; every update has shipped one.
Tier I vs Tier II (and the stacking question)
The tier rule is intuitive — Tier II is the stronger version of the same effect — and codes deliver both (the early milestone codes carry Tier I sets; 15KPLAYERS and the newer waves pay Tier II). Spend them asymmetrically: Tier I potions are plentiful enough to burn on routine farming, while Tier II stat potions deserve your push sessions — a rank-up wall, a world-boss attempt, a deliberate pity run. What nobody has documented: whether a Tier I and Tier II of the same type stack or overwrite each other, and whether two different potions of the same tier interact at all beyond running in parallel. Until someone tests it on camera, the safe pattern is one potion per type at a time, highest tier you can afford to commit.
The timing rules (where the value is)
Stat potions on, always. XP/Power/Yen are plentiful enough from codes to run near-continuously through your push hours — idle potions are wasted potions, and the beginner guide bakes them into the first-hour route.
Drop and Luck only at bosses. Statue-shard runs in Namek City, world bosses, accessory hunts in Gates — the low-percentage moments are what the scarce potions are for. Whether they move a specific drop table is usually untested; they’re still the only lever you have.
Damage for walls, not wandering. Save them for the quest tier or gate rank you currently can’t clear.
One closing caveat in both directions: if a potion feels like it’s doing nothing, remember nobody outside the dev team knows the real numbers — and if a wiki quotes you exact percentages, ask where they got them. Ours come labeled, or not at all.
