Do the tools store my data?

Only in your browser (timer history, checklists). Nothing is uploaded to a server.

Are the tools accurate after updates?

Tool inputs carry checked dates; after each game update we re-verify rates and prices and refresh the labels.

Do I need an account?

No — every tool runs free in your browser.

Can the odds calculator guarantee a class?

No. It computes probabilities under a stated no-pity assumption; nothing in the game guarantees a roll.

Quick answer

The roster at a glance

Rates come straight from the in-game spin screen. Pack Mule's carry bonus is the only effect the game shows — every other effect carries an explicit unverified label instead of a guess.

How spins work

The spin economy

Spins are the only way to change class, and Gems are the only spin currency — so every Gem source funnels into this screen.

Each spin costs 40 Gems and rerolls your class immediately.
Rates are single-spin odds. Over many spins your average converges to 1-in-2.5 for Starter-style rates.
No pity system is visible: a 0.1% class can take far longer than its average. The odds calculator shows both the average and the 90/95% safe numbers.
Gems come from run completions, Chapter 2 (+25 observed), codes, and daily rewards.

How we label facts

What 'verified' means here

Effect text only counts when the game itself displays it — not when a wiki or article asserts it.

Pack Mule — verified. "Carry 50% more hay in every bag" is printed on the spin UI.
Everything else — unverified. No checked build shows their effect lines. Community guesses stay out of the table.
Rates and effects re-verify after every update; this page carries the checked date so staleness is visible.

FAQ

Class questions

Straight answers with the evidence status attached.

What does Pack Mule do?

Carry 50% more hay in every bag — the effect line is visible in the spin UI, making it the only fully verified class bonus.

What do the other classes do?

Their effects aren't shown in checked builds. We label them unverified rather than guess — names like Forkmaster suggest Pitchfork synergy, but that's inference, not fact.

Can I change classes?

Yes — every spin rerolls your class. There's no pick-your-class; it's the game's gacha.

Which is the rarest class?

Ultimate Farmer at 0.1% — about 1,000 spins on average (~40,000 Gems) without any visible pity system.

Checked, not copied

Rates were read from the in-game spin screen frame-by-frame and re-checked after updates — not scraped from another wiki.

Unknowns stay unknown

Where an effect is unverified, the table says so. Guessing effects would poison every decision you make with the data.
