A Pokémon can use up to four different moves in order to battle opponents in the Battle Tower. These moves can either damage the opponent, improve the Pokémon's stats, or alter the flow of combat. Although borrowing heavily from the Pokémon video games, their mechanics have been simplified for use on GPX+.
All moves under GPX+ have three common attributes: Typing, Category, and Grades.
Moves can have one of eighteen types: the eighteen elemental types from the core series games, such as Water or Rock, and the ???-type (previously used for Curse, depreciated in Generation V). Damage-dealing moves are all assigned an elemental type, while non-damaging moves are classified as ???-type. GPX+ has a total of four attacks per elemental type.
Pokémon will do more damage using a move that shares its elemental type(s), similar to the Same Type Attack Bonus (STAB) awarded in the video games.
Damage-dealing moves can be sorted into two categories, Physical or Special attacks, using the respective Pokémon stat (Attack/Defense or Special Attack/Special Defense) to perform damage calculation. There are four attacks per elemental type, two being Physical attacks and two being Special attacks. A third category, the non-damage dealing or Status category, can improve a Pokémon's statistics, alter the properties of certain attacks, or cause other miscellaneous effects. All Status category moves are of the ???-type.
Status moves affecting a Pokémon's statistics work similarly to core series games. Raising or lowering the statistics influences the damage dealt or received by the Pokémon or its Speed. Each statistic starts at stage 0 (dealing or receiving x1 damage) and can be raised to stage +6 or lowered to stage -6. Moves that "sharply raise" a statistic raise the stat by 2 stages and moves that "sharply lower" a statistic lower the stat by 2 stages. Note that each move raises or lowers only one specified statistic, so to raise or lower a different one, a different move must be used. The damage multipliers can be seen in the table below.
Unique to GPX+, all moves are classified into one of two grades: Strong or Weak. Each elemental type has two Strong attacks and two Weak attacks, one each classified as a Physical or Special attack; thus every type has a Physical Strong, Physical Weak, Special Strong, and Special Weak attack. Status attacks can also be Weak or Strong.
Strong attacking moves have a greater move power than Weak moves (90 versus 50), while Strong status moves are considered to have a greater overall impact on the battle; as a drawback, however, any Strong move uses 1 of 3 of a Pokémon's Power Points (PP), which cannot be replenished during battle. After a Pokémon runs out of PP, Strong moves cannot be used again for the rest of the battle.
GPX+ does not use a specific term to differentiate Strong moves and Weak moves. The term "Grade" was invented for use in this wiki to better classify and explain moves.
Newly-hatched Pokémon begin with four default moves that match its elemental type(s). A single-typed Pokémon will have access to all four moves of its type, while dual-typed Pokémon can use the two Weak attacks for its two types; it cannot access any of the Strong-grade moves of either of its types.
A Pokémon's moveset can be modified by selecting the "Attacks and hold items" option from its drop-down menu. This provides the user the opportunity to swap out one of its moves for one of the Status-class moves, for example. Users can also elect to have the Pokémon hold one of the elemental Gems, which grants the Pokémon access to Weak-grade attacks of the type corresponding to the Gem.
Pokémon must have at least one attacking Weak-grade move in their moveset to make sure it can deal some damage every turn (an all-Strong grade moveset would make it unable to attack after three moves, for example). Additionally, a Pokémon cannot equip a Gem if its attacks could do super-effective damage to the Pokémon (meaning that Charizard cannot equip a Rock Gem, for example, because it is weak to Rock-type moves).
List of Moves
The following table showcases the different moves found on GPX+. Note that damage-dealing moves do not have any additional effects, such as an elevated Critical Hit rate or the ability to deal a Status ailment (which do not exist in the Battle Tower anyways). The powers of the attacks tend to correlate with their values in the video games.
