basics
if finding out yourself isn't enough, here's a complete guide to the core mechanics of auth's rng, including rolling, probability systems, and all the modifiers that affect your luck.
press the roll button above the "total rolls: x" counter to roll manually. if you'd rather sit back, enable auto roll using the button in the bottom-right corner - it will roll for you continuously.
keyboard shortcuts for rolling:
-
spaceor+- roll -
w- simulate a click wherever your mouse is hovering -
a/left arrow- navigate pages left -
d/right arrow- navigate pages right
auth's rng uses a weighted probability system. each rarity has a base chance (e.g. 1/100), and on every roll the game picks a rarity from a weighted pool. that base chance is then modified by several stacking factors:
effective odds = (base chance) × (luck multiplier) × (pity boost) × (dry run boost) × (daily variance) × (streak bonus)
the underlying random number generator is a 256-bit xoshiro256ss prng, seeded at startup.
example: a 1/100 rarity with a 2x luck multiplier becomes 1/50 effective odds.
your luck multiplier is a core stat that scales all of your roll odds multiplicatively. it can be increased through:
- shop upgrades (luck boost)
- consuming anomalies
- potions
- gauntlet rewards
- starmap void market purchases
- prestige luck bonus from crystallizing
- various late-game upgrades (runes, block upgrades, etc.)
pity is a safety net that prevents absurdly long dry spells on rare drops. it only applies to rarities of roughly 1/100 or rarer - common rarities don't have pity.
soft pity: begins at 65% of the maximum threshold. your odds for that rarity start scaling up smoothly, reaching up to a 10x boost as you approach the hard pity cap.
hard pity: if you hit hard pity (roughly 1.5× the statistical expectation without getting a rarity), you are guaranteed to roll that rarity on your next eligible roll.
pity resets the moment you obtain the rarity it was tracking.
if you've been chasing a specific rarity and keep missing it, the game applies an automatic luck boost exclusively for that rarity:
- kicks in after 5+ failures on a target rarity
- increases by 4% per roll after the threshold
- caps at 55% (or higher for extremely rare rarities)
- resets to 0 the moment you roll the target rarity
example: you want "paradox" (1/2000) but haven't rolled it in 50 tries. dry run boost = (50 − 5) × 4% = 1.8× multiplier just for paradox.
hot pulse is a 4-roll bonus window that activates automatically after you roll a very rare rarity (tier 3 or higher). during this window, all your odds receive a flat +18% boost on top of your other multipliers. the bonus expires after 4 rolls.
every day your luck gets a small random offset of ±6%, calculated from the current utc day. it resets at midnight utc. it's a cosmetic quirk - some days are luckier than others, but over time it averages out.
every 100 rolls, you receive a 4× luck boost for 1 minute. a large countdown overlay appears on screen during this window. this is entirely beneficial - nothing to worry about.
anomalies are rare drops earned whenever you roll a rarity rarer than 1/10,000. each anomaly you consume grants a permanent +0.5× luck boost that stacks indefinitely.
you can consume them one at a time or all at once using the buttons in your inventory section. the more anomalies you stack, the more your base luck compounds over time.
in certain situations (such as after a mutation), a popup appears giving you three options for what to do with a result:
| option | effect |
|---|---|
| keep | adds the rarity to your inventory normally |
| sell | converts it to points immediately using the standard formula |
| pass | discards the result entirely - nothing added, no points earned |
the bell icon in the bottom-left corner opens your notification center. it logs everything during your session:
- anomalies earned
- potions activated
- gauntlet rewards claimed
- items sold
- and more
unread notifications show a badge on the bell. you can mark individual ones as read, delete them, or clear everything at once. notifications persist across sessions.
desktop: use the arrow buttons on the left/right screen edges, click the dots at the bottom, or use keyboard shortcuts.
mobile: swipe left or right anywhere on the screen.
some pages - mutations, starmap, and runes - are hidden until you unlock them by completing the relevant gauntlet tier.
for players who prefer the old layout, legacy mode disables the multi-page swipe system and shows everything stacked vertically on one long page. enable it under settings. in legacy mode, the shop and settings are accessed via floating buttons in the top corners instead of pages.
