Unlimited Experience (no cheats involved)
In order to do this you firstly need any spell or ability that will attack a group of enemies, i would reccomend an ability that doesn't use up any MP so that this can be done for an unlimited length of time, for example: i used wind sickles as once it has been learned can be used with any vocation as long as you have no weapon equiped.
Now, this ability needs to be strong enough to defeat the slimes outside of bloomingdale in two hits, but still weak enough not to kill them in one shot. And it should be noted that you will need your agility to be high enough for you to attack first each time.
Now, as you will have noticed, the slimes outside of bloomingdale will not attack you, but simply call for more slimes to appear until there are 8 on-screen and then they merge into a king slime. But, you should take note of the fact that one slime requires a turn in order for the whole group to merge.
So this is how the technique works, you need there to be four slimes on screen to begin with, so if there are two defend for a turn so that there are four. Now use your ability or spell on these four slimes which will now mean these four slimes will die on the next hit. Next these four slimes will spawn four more slimes so that there are now 8, but they cannot merge as none of them have a turn left. Now you simply use the ability or spell again, and this will casue the four that were originally there to die, but make it so that the other four will now die on the next hit. These four will then spawn four more, and you should use the ability or spell a third time, and the same will happen again. And this process can be repetead for as many turns as you like.
The only potential problem with this is that occasionally one slime many get a move in edgewise, resulting in the formation of the king slime too early, but with a high enough agility skill this should not occur.
I hope this will have been of some sort of help :D
