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

SP is an acronym and is known to stand for Spell Power or Spell Points, sometimes referred to as Mana as well. It is the essence of power that lets the player's character perform skills. Max SP is mainly derived from the class of the character, INT, and any equipment that may affect 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 = Math.floor( MAX_SP * TRANS_MOD );

MAX_SP += SP_MOD_A;

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

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.
