So I'm going to post the best MAG for free players that don't want to spend AC.
MEL, RNG, or TEC needs to be a total of 150 or 100 (This is base off race and class you want to use.)
DEX needs to be 50 or100
This MAG will work for main and sub Braver, Bouncer, Hero (not sub-able), Phantom (sub-able), and Etoile (sub-able) Class.
Braver, Bouncer, and Phantom use DEX
Hero and Etoile use MEL, RAG, or TEC
This part here are class tree skills
Braver MAG = DEX Converts to MEL and RNG 100%
Bouncer MAG = DEX Converts to MEL and TEC 100%
Hero MAG = Converts Total attack stats and redistributes them into MEL, RNG and TEC 100%
Phantom MAG = DEX Converts to MEL, RNG, and TEC 100%
Etoile MAG = Converts Total attack stats and redistributes them into MEL, RNG and TEC 100%
Example 1 - 100 MEL, 25 RNG, 25 TEC, 50 DEX
Example 2 - 150 MEL, 0 RNG, 0 TEC, 50 DEX
So right now I'm playing with 50/50/50/50 base mag, and so far working really well.
So there you have it the best and optimal free MAG for players that don't want to spend AC and play all classes on one character.
