History PeninsulaOfPowerLeveling / Pokemon

* The games have a modified experience rate boost that allows low-leveled Pokemon to catch up really quickly. They also give Lucky Egg[[note]]held item that boost experience gain of the Pokemon holding it[[/note]] fairly early on. There is also "shaking grass" which has a high chance of encountering Audino, a Pokémon that yields a high amount of experience, as well as dark grass which has tough Pokemon but grant better experience than the ones found on normal grass. Pinwheel Forest is particularly useful for shaking grass grinding in the early game; there are several areas where you can walk around on empty ground with ease until you see grass shake, there are two different Fighting-types capable of exploiting its main weakness nearby; even if you're not interested in those, you're given an unlimited-use TM of the Fighting-type move Rock Smash, and when things start to go south you can just walk out of the forest and talk to a nurse for an instant heal.
* While rematches have been removed, this Gen has many daily repeatable trainer matches like the Nimbasa Stadium. ''Black 2 and White 2'' also have the Black Tower (for Black 2) and White Treehollow (for White 2). Both are the same areas which have a random, maze-like route with trainers you can fight leading up to the "boss" of the floor. You can repeatedly challenge the floor and lower floors net tougher enemies. Even better, the Pokemon Breeder trainers in this area have two members of the [[PinataEnemy Chan]][[StoneWall sey]] family, which (aside from Happiny) give out the most EXP in the games.

* A unique new mechanic added to all Breeders, a type of NPC trainer class you can battle, allows to you re-battle them whenever you leave the route or area they're encountering in. Breeders show up randomly in the Nimbasa stadiums after defeating the Champion, as they did in Black and White, and give out Rare Candies, an item that instantly boosts a Pokemon's level by 1, when defeated there. The kicker is that the rematching mechanic and the Rare Candy rewards are ''not'' mutually exclusive, nor are they restricted to once a day--you can effectively grind Rare Candies indefinitely if you're lucky enough to get a Breeder or two in one of the stadiums.

** In the first Pokemon Center you encounter, there's a trainer who will rematch you as many times as you want. His Pokemon are very weak, but healing after each battle is only a few steps away.
** Your rival, Theo, will join you several times to double-battle your way through an area, and will fully heal all your Pokemon after each battle, making it easy to continue LevelGrinding for as long as you want.
** Theo will also hang around near the Labyrinth for infinite rematches, until you advance the plot. He's strong, but predictable; with a good counter for each of his Pokemon, you can advance levels quite quickly.
** After completing the optional Ninja Reunion side-quest, you can have as many rematches as you want against six different ninja, each using 5 copies of a single Pokemon species (one for each type of Effort Value), or directly train Effort Values for each stat for free. This is especially helpful because since they only use one species each, it's very easy to play ElementalRockPaperScissors and quickly defeat them all over and over again until you've run out of PP. Training up to level 100 becomes quite feasible.
