Arena:

MLG’ State Highschool.

A typical highschool. It has a large building complex with a variety on different classrooms, a great stone terrain, a comfortable grassy area with trees (also reffered as the ‘Schools Garden’), a basement that has soft sofa’s, it’s very dark in there though and a big fountain in the middle of the stone terrain. The rooftop of the entire complex is flat so suitable for battle, only reachable if you have a Flying pokemon or a pokemon that has the Teleport ability. The various classrooms all have their pros and cons:

Videoroom: All seats are spread to the back, rather open classroom ideal for close combat.

Chemistry room: Dangerous. Crowded with seats and a lab. Touching the chemical tubes and potions will resolve into a -5 HP loss. Touching the Ether on the end of the classroom, ontop of the high closet will result into a +5 Energy raise. Poison type moves get a +2 Attackpower boost. (Read: Not the pokemon, but the move.)

Aula/Theater: Big room with lots of seats. A typical aula, nothing special.

Basement: Rather open terrain, very dark and creepy. Dark and Ghost pokemon are advantidge here.

Rooftop: Flat and empty. Flying and Dragon pokemon get a boost up here. Falling off results in a -12 HP loss. (It is high, remember)

Moisty Forest: The schools forest, it is located one mile from the grassy area. Creepy place, the forest is not kept tidy by the janitor. Bug and Grass pokemon get a boost.

Gym: Wide open space. Fighting pokemon get a boost. It has various gym equipment that can be used to power up attack. (+1 attackboost)

Kitchen: The schoolkitchen. A dangerous place, without you expecting it. It has knifes, hot plates, all kinds of things to throw. Fire pokemon get a boost.

Circuitroom: A room that no-one is allowed in. How to get in, no one knows. Electric and steel pokemon get a boost in here.

Stone-courtyard: Comparable to the indigo stadium. Just a plain battle terrain, out of stone. The pond in the center gives water pokemon a boost and they regain health in it. (+2 HP)

All battles start on the right side of the fountain, on the stone floor.

Any takers? Ref?
