Nearly everything in the game has a unique ID, which is what those are. The first one is the ID of the character that the command belongs to. When creating a similar command, it can often be replace with the character_name . The second is the ID for the repeating attack, which can often be replaced with its position among the other repeating attacks (e.g. something like %{ character_name |repeating_attack_ $1 _attack} where "$1" is the second attack in that repeating section.) The reason its so complex is a repeating action has to have a unique ID that differs from everything in the game, such as a rollable table item or a card in a deck.
