Experience

Experience is a vital in-game system by which certain characters can progress through the game via level up. The system has a set number after each level up which has to be completely depleted to zero in order to progress to the next level. The set number can slowly be depleted after defeating enemies, different enemies provide different number of experience once they are defeated. The set number increases after each level up therefore meaning harder to reach the next level.

Variants
In Kingdom Hearts the overall number of experience really depends on what type of enemy it is and at what point through the game they are defeated i.e. battle level. The battle level shows how strong the enemies in the selected world are and hence more experience points are obtained once they are defeated. As characters progress through the level table they will be rewarded with boost in HP or MP and learn new abilities.

In Kingdom Hearts II experience is obtained after defeating enemies and the overall amount obtained varies accordingly in relation to the battle level. However unlike Kingdom Hearts experience points are not obtained after defeating bosses instead bonuses are obtained. Furthermore there are also newer sub-counterparts to the battle level system such as Moogle level ups, Drive Form level ups and Summon level ups. Of which they have their own requirements for level up. It's harder to level up in Kingdom Hearts II due to the fact that experience can not be obtained after boss battles or in the Underdrome tournaments.

Experience is obtained by characters Sora, Donald, Goofy and guest characters in both titles.

Hints and Tips
- In Kingdom Hearts leveling up is done easily through juggling Rare Truffles, they give you heaps of experience after 100 juggles.

For those without the patience and/or skill to juggle Truffles, or for those who just like to hit things, quick leveling is done via repeating Seeds 10-1 in the Hades Cup repeatedly until level 70, at which point you can easily complete the Time Trial for the Hades Cup. Doing so allows you to "choose" who you wish to fight. A very good experience/hour income is accomplished by repeatedly killing the Rock Titan, who awards 4000 Experience, and ~100 Technique, or Tech, experience per kill.

For those who haven't completed the Time Trial and don't have access to the "choose" feature, repeated Ice Titan killing is also decent, and actually better if you don't care about what level your companions are and are under 55 Strength (The reason for the Strength requirement is because as your Strength increases, the time required to kill the Rock Titan becomes shorter due to harder attacks. The Ice Titan fight is all about deflection, and the shards you deflect do the same amount of damage at 80 or 40 strength). The Technique experience gained from the Ice Titan is almost as much as you get all at once for killing him, although the fight takes a little longer and is a tad harder for some, it's excellent for leveling Sora by himself.

- In Kingdom Hearts II the best way to level up via experience at the peak of Pride Rock. Heartless spawn repeatedly here and leveling is a breeze. Just be sure to bring some potions. - Another excellent place to level is to go to through the Organization XIII castle with experience boost and the Gullwing keyblade equipped. Turn off Donald's heals and go into low hp when the bar is flashing red. The exp gains will be from 1500-3000 per kill. It should be noted that this method is risky and should be done when the Nobodies in the area can be killed at a decent rate. The nobodies usually come down if you jump up at them.
