Assist (VA) -- The user's hand or paw glows with energy, and shoots out a random projectile attack which one of its trainer's other Pokémon which were brought to battle. It cannot select from fainted Pokémon’s attacks, nor Pokémon who are on the field with it at the time the attack is used. There is no limit to what will come out of the hand: Bulbasaur vines, String Shot, etc. are all possible to come from the "cat's hand." The randomly selected attack is usually of the type of the Pokémon the user emulates, and is usually a weak to moderate level attack.)
The attack descriptions are mostly derived from the ones on the PASBL site and even though it is not strictly followed, most attacks are in agreement with either the PASBL descriptions or the anime descriptions which can be found on Bulbapedia. Also, Tess and Arc are working on their own FB attack descriptions, which probably will take time, but once they're done, they'll be followed. Also, the attack description from PASBL are only majorly used for Trainer Battles. For RPing, the attacks are a lot more flexible like in the anime (where things like Thunder Wave dealing damage happen).
