Punch Walls To Escape Class Roll Odds
Pick the class you want. The calculator uses the odds printed in the game panel and the PITY 0/8 rule, then shows how many rolls that target usually costs, what your chance is after any number of rolls, and whether buying it outright at its gem price is cheaper.
Roll odds for one class
The odds come from the class panel itself. The panel does not print what one roll costs, so leave that field empty and you still get the roll count.
| Rolls | Chance of X-RAY | Gems at that count |
|---|---|---|
| 1 | 4.50% | add gems per roll |
| 5 | 20.6% | add gems per roll |
| 10 | 36.9% | add gems per roll |
| 25 | 68.4% | add gems per roll |
| 50 | 90.0% | add gems per roll |
Expected rolls is 1 divided by the printed odds, so it is an average and not a promise: unlucky runs go well past it. Rolls are independent, so 0 rolls already made do not shorten the next one — your next roll is 4.5% either way. Buying X-RAY outright costs 1,000 gems.
Pity: the panel tracks PITY 0/8 and says every 8 dummies gives a rare or better. Across the printed odds, 18.5% of rolls are rare or better (76.1% chance of at least one in seven tries). The pity roll is rare-or-better, not your target, so it does not change the odds column above, and the counter's reset rule is not recorded in the game UI. The printed percentages add up to 100.5%, which is rounding in the panel, not a weight you can multiply out.
How to read the result
Expected rolls is one divided by the printed odds, so a 4.5% class averages 22 rolls. That is an average across many players, not a timer on your account: half of players get the class within the median figure, and the other half take longer. The 90% column is the number you plan a gem budget around.
The pity rule
The class panel tracks PITY 0/8 and states that every 8 dummies gives a rare or better. Rare-or-better is 18.5% of the printed odds, so the pity roll is a floor on the rarity band, not a guarantee of the class you picked. The panel does not say how the counter resets, and this page does not pretend to know.
Roll or buy outright
Every class also has a direct gem price on the panel, from 160 for PACK RAT to 12,000 for THE ANOMALY. The one number the panel never printed is what a single roll costs, so no page can honestly tell you which route is cheaper yet. If you have seen the roll price in your own game, type it in: the calculator will compare the average roll cost against the direct price and you get the answer for your version.
