Abilities
Abilities are intraneous faculties that all Pokémon inherently have upon obtaining them.
Abilities perform passive effects in-battle for Pokémon; they can be beneficial, hindering, or bilateral in nature. The possessor is usually the beneficiary of the ability, but some, such as Dry Skin, can have a countereffect; or in the case of Truant, for example, it may have a strictly hindering effect as a needful counterbalance.
While some abilities also performed out-of-battle functions in the official games, this is not the case in Pokémon Revolution Online; most out-of-battle functions, such as spawn-predeterminers, have not been functionalized, here, due to the belief that it may disbalance the encounter rates of potentially rarer Pokémon, so most abilities are modomodal for their in-battle functions.
Bear in mind that not all abilities have been programmed in PRO, yet; they will be distinctly marked on the tabular list below.
Mechanics
Using
These abilities are mechanistically similar to passive abilities in other RPGs; they are not manually activated by the user, since they are performed automatically. They will actuate when all the requisite conditions are in effect or, for unconditional abilities, when a possessor of the ability is deployed in-battle.
Determination
All Pokémon species have subsets of up to three inheritable abilities, but only one is possessable per individual Pokémon; this is predetermined upon obtention.
For technical purposes, these functions are categorized as predominant abilities and hidden abilities. Predominant abilities comprise up to two slots (referred to as Ability 1 and Ability 2), whereas hidden abilities (HAs) have a 5% chance of inheritance by the Pokémon.
The Hidden Ability odds can be enhanced to 25% with the activation of a Black Medallion, which is purchasable from the Coin Shop or from other players through Trade Chat, and lasts for three days after it's activated. You can deactivate the Black Medallion at any time by speaking to Psychic Tamaro in front of any Department Store. Time elapsed while deactivated does count towards the effect's three-day duration, and you can reactivate it at any time via the same NPC.
Changing
Generally speaking, the Pokémon's inherited ability is unchangeable. Although various moves and abilities (see below) can temporarily alter it during battle, there are only a few ways to change it permanently.
One caveat is when the inheritor evolves; if the evolved form has a different ability homologous to the current ability's slot or if the evolved stage has a mono-ability (Metapod's Shed Skin ability, for example), that ability will supplant the pre-evolution's ability.
The Ability Capsule, which can be purchased at any PvE Shop or PvP Shop for 250 PvE Coins and 150 PvP coins, respectively, will allow the player to change the ability of a Legendary Pokémon. You will be able to choose which ability you want.
