How to Read Potion Value
Potion value is not theoretical power. It is how much easier the next dangerous node becomes after you click. Keep the bottles that solve elites, bosses, or ugly draws. Spend the rest before a full belt turns future rewards into dead drops.

Count badges on this page always show what they are counting, such as potions in a timing bucket, potions in a pool, or potions added by an unlock wave.
3 potions
Carry them for pathing
Use these when the bottle changes route quality, saves a Rest, or keeps the next dangerous node clean.
32 potions
Spend them for tempo
These are made for the turn that wins a race, fixes a draw, or removes one enemy cycle immediately.
19 potions
Save the ceiling
These scale hardest when the fight is long, the matchup is specific, or the payoff is simply too large for a hallway.
10 potions
Keep one panic button
These are strongest when a fight is about to get away from you. They are there to stop the bleed, not look pretty.

Potion Timing Calculator
This calculator is displayed here near the top of the page, directly below the opening timing guide. Pick the bottle, describe the room, and let it push back against the usual bad habit of holding everything forever.
Lean toward using
Entropic Brew is close to a profitable click.
Its ceiling is still ahead of you. Unless slot pressure is biting, the better payoff usually arrives in an elite, boss, or any longer fight.
Best trigger
Save it for the first elite, boss, or long fight where the extra ceiling changes the result instead of just padding a clean win.
If you wait
Overholding is the danger now. If the hard fight has arrived, keeping it for a mythical better spot is just lost tempo.
Slot pressure
One more drop can force a decision. Start ranking what actually deserves storage instead of pretending every bottle is sacred.
Potion Pool Map
The pool matters. Shared bottles are the broad baseline. Character bundles widen that baseline with three class-specific picks each, while event and token entries sit outside the ordinary reward rhythm.
60 potions

The broad all-class shelf. Two general unlock waves expand it with six extra bottles.

Unlock Waves
These are the seven potion unlock waves currently tied to progression. General unlocks expand the shared pool, while character lines each add a three-potion bundle.

When to spend it
Spend it when it changes route quality, prevents a forced Rest, or keeps the next dangerous node from costing real HP.
What makes it worth holding
The hold value is pathing. If the route is still safe and your belt is roomy, waiting is fine. Once the next reward would bounce, that patience turns into waste.
Why it matters
Its real value is future HP saved, better route freedom, and not being forced into a weaker rest-site decision.

Potion Synergy Notes
The strongest potion setups usually come from slot management, refill pressure, or effects that turn every click into extra output.
Capacity first
Extra slots let you hold niche answers without turning every new drop into a forced discard.
Refill engines
Once the belt refills itself, potions stop being luxury storage and start becoming part of the route plan.
Convert clicks into swing
The strongest potion pieces do not just store value. They turn the click into damage, tempo, or another fresh bottle.
Know the tradeoffs
Some relics reward empty slots or shut the supply off entirely. Those tradeoffs change how every bottle should be valued.
Potion FAQ
What does the timing calculator actually weigh?
It weighs the potion's normal timing window, the current fight context, how much pressure you are under, and how close your belt is to clogging. The point is not perfect play in a vacuum. The point is cleaner live decisions.
Are character potions in the same pool as shared potions?
No. Shared potions come from the common shared pool once their general unlock waves are open. Character unlock lines add their own three-potion bundles on top of that.
When should I drink route-heal potions?
Drink them when the heal changes pathing, prevents a forced Rest, or keeps an elite line open. Drinking early for empty comfort is usually how value leaks out.
Why spend a common potion before the next elite?
Because a common potion that saves one attack cycle or one bad turn has already paid for itself. The real waste is losing the next reward because the belt stayed full for no reason.
