Rank ladder
Some effects display a letter grade instead of a number. Those store a rank index rather than a percentage.
The ladder
Section titled “The ladder”24 tiers. Ascending:
F- F F+ E- E E+ D- D D+ C- C C+ B- B B+ A- A A+ AA- AA AA+ AAA- AAA AAA+The strings sit consecutively in lang_0003.bin at list indices 1472 to 1495.
Mapping a stored value
Section titled “Mapping a stored value”rank = LADDER[value + 6]Value 0 is D-, value 11 is A+, value 16 is AAA, value 17 is AAA+.
Range in practice
Section titled “Range in practice”Graded set bonuses sit at A+ or below, with one exception: Grace of Magatsuhi’s 7 piece bonus stores value 16, which is AAA.
Ultimate Stamina unlocks Rank AA for Agility and Toughness, so tiers above A+ are reachable on stats as well as on effects.
