• in this game whenever you cast a self buff, healing or status purge on yourself you gain 30 EXP and 60 JP regardless of your character LV,

• when you cast a buff, heal, status purge on an character who is 4 LV higher, you'll get 60 EXP 120 JP and this is the maximum amount of JP you can get from buffing allies, higher LV gap would just result in the same EXP/JP gain.

• the general grind method here is to setup an AFK grind on certain characters then use them as an buff fodder to LV up other characters

• the first thing to do is go to option , turn off battle animation and turn everything animation related to the fastest
  

this is the easiest grind you can do, you can just setup the grind then alt tab out, watching a movie or doing some housework while leaving the game grind for you.

requirements :
a dark side weapon. This is a must have, to get dark side weapon just buy the cheapest bit weapon in the shop then keep upgrading them until you get a dark side version, it's not hard you can get one after 3 or 4 tries.

equip the dark side weapon on Mars or Luna, go to the simulator battle 1 LV6. Proceed to kill all 3 enemies and leave only the sniper or assault / tank alive, you must kill the scout enemy because they will mess up the grind.

after you defeat 3 enemies, use warp to warp into the closed space between boulders. Then turn on auto battle and you are done, Mars / Luna will keep using heal and recover over and over, just leave it and do something else, after 1 hours you can reach LV200.




this method is meant for characters who don't have the warp skill, all assault, tank, scout characters can use this method

requirements : a flare machine gun, flare sword if you intend to grind 2 characters at one go

now start the story stage 2 simulation where you fight Luna and Dark walker

take down Luna, then lure Dark walker to the top left corner of the map, after that turn on auto battle then enjoy your AFK grind, it's recommended to change your character class to the first tier because it cost less SP.


if you have done anything correctly your character will be sandwich'd by Dark walker and will keep using buff or heal over and over, leave the game alone for 1 hour then come back boom ezy grind

to grind 2 characters place the one with flare sword behind the other character who has flare ranged weapon on them.

start the treasure hunter battle simulator, bring sun and 2 more buffers and Terra with 50% big bang gauge gain skill, on first turn just rush Sun to the enemies, have buffers give her max offensive buff then wait for a turn, on turn 2 you can cast Sun's gravity force skill and it gonna wipe half of the enemies, pass a turn then use gravity force again to clear the map. Each clear gives you 20000 SG. The general gist is to clear the stage as fast as possible.


this method is used for grinding multiple characters at once when you are too lazy to do them manually.

first thing to do is get as many dark side weapons as you could, equip them on whoever you want to grind, bring them to the treasure hunter simulator battle, turn on auto battle and let them do the grind, because dark side weapons drain HP on the start of turn the AI would try to recover or heal whenever they act, some will attack enemies too. With this AFK grind you can alt tab out to do something else, you can get decent SG too.
