801.2 A player’s range of influence is the maximum distance from that player, measured in player seats, that the player can affect. Players within that many seats of the player are within that player’s range of influence. Objects controlled by players within a player’s range of influence are also within that player’s range of influence. Range of influence covers spells, abilities, effects, damage dealing, attacking, making choices, and winning the game.

801.2a The most commonly chosen limited ranges of influence are 1 seat and 2 seats. Different players may have different ranges of influence. Example: A range of influence of 1 means that only you and the players seated directly next to you are within your range of influence. Example: A range of influence of 2 means that you and the two players to your left and the two players to your right are within your range of influence.
801.2b A player is always within their own range of influence.
801.2c The particular players within each player’s range of influence are determined as each turn begins. Example: In a game with a range of influence of 1, Alex is seated to the left of Rob, and Carissa is seated to the right of Rob. Carissa is not in Alex’s range of influence. If Rob leaves the game, Carissa will enter Alex’s range of influence at the start of the next turn.
801.2d An object is within a player’s range of influence if it’s controlled by that player or by another player within that many seats of that player. In addition, a battle is within a player’s range of influence if it’s protected by that player or by another player within that many seats of that player.
