Max SPhttps://irowiki.org/classic/Max_SP

Max SP affects SP Recovery, Increase SP Recovery, and Spiritual Cadence.

var BASE_SP = 10;
BASE_SP += BASE_LEVEL * SP_JOB;

var MAX_SP = BASE_SP;

MAX_SP = Math.floor( MAX_SP * (1 + INT * 0.01) );

MAX_SP += SP_MOD_A;

MAX_SP = Math.floor( MAX_SP * (1 + SP_MOD_B * 0.01) );

MAX_SP = Math.floor( MAX_SP * TRANS_MOD );

Where:

SP_JOB: See the job modifier table

SP_MOD_A: Sum of additive modifiers

SP_MOD_B: Sum of multiplicative modifiers

TRANS_MOD: 1.25 for transcendent classes, 1 otherwise

Notes:

Base SP is the same for all characters with the same job and same level.

Increase base SP by 1% per 1 INT. Then add +x SP modifiers. Finally add +x% SP modifiers.
