Any cheats for this game ? I wanna try it out and heard its kinda grindy
For the game itself there is a combo which is very strong and will clear you the game first playthrough, no need for any grind at all, although encounter rate during first playthrough before you can use nana can be an issue as trash mobs will take more than 1 turn with starter party...
The combo I talk about is Rei, Konoha, Kenshin and Nana...
Basically what you do is:
Cast up to 2 unique buffs of rei(unity and inspire).. the kenshin atk buff(and def/mdef one if needed, but it shouldn't be).. konoha does her beast stance into jinguuji's pride.. nana spams illumina forge...
After 2 turns of buffing(1 turn for some characters) simply keep spamming nana illumina forge so everyone is at full TP each turn and the 80 TP attacks with the konoha/kenshin/rei...
As for non boss fights - nana's aoe are the trick to them in NG... rush those ASAP.. also when selecting classes - make sure you select science class 10 times for SP regeneration accessories which will allow nana to kill trash mobs infinitely... simply equip nana with best agility in party and she will always move first and kill everything with her aoe.
This will be 0 grind easy game clear.
Once you beat game once - you unlock a 'cheat code' by the game, which is an item which instantly kills enemy with no animation, meaning it's super easy to farm absolutely anything with it. The only thing it can't kill is hidden boss.
Also you can skip all dungeons and get 'hide' illumina which allows you to remove all encounters.. so 2nd playthrough is much faster(4-5 hours)
As for hidden boss - he unlocks all scenes... and since without it you would need 6 playthroughs(loads of time) and you essentially don't miss much other than a bit romance before scenes by just going outright for the hidden boss.
Hidden boss can only be encountered in NG+ and his area unlocks once you reach last megiddo in hall of training and beat the last boss there.
Hidden boss himself... honestly I heard people having trouble with him but I killed him in 2 attacks with the above party and buying 2x muscle power(+50% attack stat) for konoha and kenshin... simply buff up like usual... konoha will deal around 300-400k damage with those and kenshin will deal around 200-300k... that's enough to take down both phases of boss on same turn without even seeing what it has to offer.
