The database answers what the number is. These answer what it means.
Every figure comes from the same datasets as the rest of the site.
Gacha mathsWhat a featured unit actually costs, in every game we trackThe advertised rate tells you almost nothing about what you will spend. Here is the same question — how many pulls to land the unit on the banner — answered identically for all 19 games we track, from 50 pulls to 167.August 25, 2026 · 6 min readGacha mathsEvery pity system, in one tableNineteen games, and no two of them promise the same thing. Here is where each one's odds start climbing, where they stop, and the four that never owe you the unit at any count.August 25, 2026 · 4 min readGacha mathsSoft pity, and why the banner's rate is not the rate you experienceA 0.6% banner does not give you a 0.6% chance on pull 75. Here is what the ramp actually does to your odds in each of the eight games that run one, and why the number in the corner of the banner is technically true and practically useless.August 25, 2026 · 5 min readGacha mathsThe unlucky tail: the number the average hidesTwo games can average the same number of pulls and cost wildly different amounts when it goes badly. The gap between a typical run and an unlucky one is the number worth planning against, and here it is for every game.August 25, 2026 · 3 min readGacha mathsWhat one pull costs, in each game's own currencyA pull costs 1 of something in three games and 600 of something in another. Here is the per-pull price and the full chase in every game that names one — and why turning those into a single league table would be a lie.August 25, 2026 · 2 min readReading the dataWhich games tell you the odds for the unit — and which only tell you the tierEvery gacha publishes a percentage. Only a handful publish one per unit. Here is exactly how precise each game's disclosure gets, and what that means for the number you are planning against.August 25, 2026 · 3 min readReading the dataEvery game has its own vocabulary — and why we don't flatten them"5★" means one thing in Star Rail and something quite different in Blue Archive, and two of these games don't rank their roster at all. Here is what the top rarity, the level axis and the word for a unit actually are in all 21 games we track.August 25, 2026 · 4 min readReading the dataWhat you can look up for each game21 games, 6,308 units and 191 datasets in one schema. Here is exactly what exists for each game, and — just as usefully — what does not.August 25, 2026 · 3 min readReading the dataMax-level stats are the wrong number to compareEvery roster page in every wiki ranks units by their maximum stats. That is the one level almost nobody is at, and for some pairs it inverts the answer completely.August 25, 2026 · 4 min readReading the dataHow to read a stat percentile — and when to distrust itEvery unit page here says something like "11th percentile, rank 125 of 140". This is exactly what that means, exactly how it is calculated, and the four situations where it will mislead you.August 25, 2026 · 5 min readProgressionReading a drop table: what "where to farm" actually tells youA complete drop index gives you every place a material drops. That is genuinely useful and it is also not the whole answer — here is what a drop list can tell you, and the part you still have to decide yourself.August 25, 2026 · 4 min readArknightsArknights: what Elite 1 and Elite 2 actually buy youPromotion is the most expensive decision in the game and its raw-stat return shrinks at every step.

What changes between them is which materials you farm, not how much you pay.August 25, 2026 · 4 min read
