Hi everyone, so i've been trying different ways to level up fast and I think I discovered the best and fastast way, If you have a better suggestion post it in comments so we all can benefit cause we all know how grindy and boring it gets in postgame.

First of all get Necklace of Enlightenment and use it on the players you wanna level up (you can craft this Item in armory shop. It gives slight boost in exp earnend, although from my experience i think it makes very little difference ain't bad getting it though)

Second, arrange your battle tactics. In tactic Tweaker and in Spoils settings arrange it so that you get more xp from monsters (you can see what setting you got when tweaking it, as soon as you read something about xp leave it that way)

And third and most important one get the dish called note that this item can't be cooked, you get it from quests and it's limited so use it wisely, It gives massive experience boost for 65 minutes I used 3 on all my 3 players i wanted to level up before fighting final boss. This Item doesn't expire when you kill the boss! it still counts so you can repeat killing the boss again and again, everytime you kill him you level up! the weird thing is that everytime the boss is dead item count for minutes remaining goes up! maybe this is a glitch and this makes it unlimited.

Here you go folks! happy grinding :)
