Experience

Experience or EXP is obtainable reward points as part of 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, and different enemies provide different amounts of experience once they are defeated. The set number increases after each level up therefore meaning harder to reach the next level. Tech points are also obtainable reward points and work like experience points but are awarded when the player uses various techniques in battle, like deflecting blows or exploiting enemy weaknesses.

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 (denoted with colored stars beside the world name during world selection) 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. After a main point in the game, i.e. Kairi's rescue, all enemies become stronger, and therefore reward the player with more experience upon their defeat.

In Kingdom Hearts II, experience is once again obtained after defeating enemies. The overall amount obtained varies accordingly in relation to the battle level. However, unlike in Kingdom Hearts, experience points are not obtained after defeating bosses; instead, bonuses to HP and MP, new spells and spell upgrades, abilities, and item slots are obtained. Furthermore, there are also newer sub-counterparts to the battle level system, such as Moogle level ups (for item synthesis), Drive Form level ups, and Summon level ups. These sub-counterparts have their own ways of gaining experience for level up. In Kingdom Hearts II, gaining experience is more difficult, due to the fact that experience can not be obtained after defeating bosses or in the Underdrome tournaments.

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

Kingdom Hearts

 * In Kingdom Hearts, leveling up can be done easily by juggling Rare Truffles; they drop large amounts of experience after 100 juggles, which equate to around 5050 EXP points.


 * For those without the patience and/or skill to juggle Truffles, quick leveling can be done via repeating Seeds 10-1 in the Hades Cup repeatedly until the player reaches level 70, at which point he can easily complete the Time Trial for the Hades Cup. Doing so allows him to "choose" who you wish to fight. Repeatedly defeating the Rock Titan is another good way to gain experience, as it awards 4000 Experience, and about 100 Technique, or Tech, experience per defeat.


 * For those who haven't completed the Time Trial and don't have access to the "choose" feature, repeated Ice Titan conquering is also decent, and actually better if the player doesn't care about what level his companions are, of if he has Strength under 55. The Technique experience gained from the Ice Titan is almost equal to the amount recieved for defeating it, although the fight takes a little longer and is harder for some. It's excellent for leveling Sora up by himself.

Kingdom Hearts II

 * In Kingdom Hearts II the best location to level up at is the peak of Pride Rock. Swarms of Rapid Thruster Heartless spawn repeatedly here which makes leveling up simple with long combos and Magnet-Thunder.


 * Another excellent place to level is to go to through the Castle That Never Was with Experience Boost and the Gull Wing Keyblade equipped, while using a high-level Drive Form. The player should turn off Donald's Donald Cure ability and allow himself to get hit until the HP bar is flashing red. The experience gained will be from 1500-3000 points per Nobody. It should be noted that this method is risky if Sora is not at a high level.

Kingdom Hearts Birth by Sleep

 * The best location to gain experience is the Reactor in the Radiant Garden, using a Command Deck with four Mega Flare Commands. The player needs to have the abilty "Exp Chance" activated and his health must be below 25%. Then he should take off every Treasure Magnet he has equipped, and go to center of the Reactor. Enemies will spawn at this point. After defeating them with Mega Flare, a new horde of enemies will appear. After defeating multiple swarms of enemies, the player will notice their EXP total greatly increase, because they'll gain 4000 to 5000 experience. Equipping a Keyblade that has a high magic stat is recommended, such as (Brightcrest, No Name, Pixie Petal, or Ultima Weapon).
 * Another location to gain experience is the "Launch Deck" in Deep Space. The player should make sure that the Mickey Dimension Link has its second emblem, as it provides "Double Exp" (which doubles all experience received). The player must exit from the "Machinery Bay Access" save point and walk forward until enemies appear, then summon the Mickey Dimension Link right away and defeat the enemies. This will give him between 2000 and 3000 experience. The player can then repeat this until he's at the level that he's satisfied with.
 * Another strategy is to meld the EXP Walker ability and fight Unversed, while at the same time walking and avoiding using Movement Commands, such as Cartwheel, Slide, etc. This will make the player receive the optimum amount of Experience in an average battle. The player can also use it with EXP Chance to allow a larger EXP revenue.

Kingdom Hearts Re:coded

 * In Kingdom Hearts Re:coded Outside the Coliseum in Olympus Coliseum is a good place to gain experience. Walk towards the other end of the entrance and one Air Soldier, one Invisible, and two Wizards will spawn. After defeating them, more will appear. By defeating the multiple swarms of enemies, the player will gain around 8000 to 9000 experience. Equipping Oathkeeper is recommended, due to its LV1 Clock Ability; Undo, which will protect you from the Wizards', Air Soldier', and Invisible' status effect-based attacks and its LV4 Clock Ability EXP Boost; which provide an addition boost in experience.
