Jutsu Ranks

Jutsus use the ranks E, D, C, B, A, and S. Rank is a technique classification, not item rarity: it affects learning difficulty, material cost, practice rewards, and execution complexity, but it does not automatically make a technique the best choice for your build.

Rank	Learn base	Pages	Blank scrolls	Practice steps
E	92%	1	0	2
D	86%	2	0	2
C	76%	3	0	3
B	66%	5	1	3
A	56%	8	1	4
S	46%	12	2	4

B/A learning also needs 1 catalyst per required chakra nature; S needs 2 per nature. In battle, using an S-rank jutsu applies one turn of S-rank fatigue, so another S-rank technique cannot be used immediately until you take a non-S action.
