Accept Aid is a button under the Settings menu that lets other players cast teleother spells and Vengeance spells on the targeted player. While in a waiting room for Barbarian Assault, it allows players to receive recruitment requests. It is pretty much only useful in members' worlds as there is no situation in which aid can be offered in free-to-play with the exception of Christmas crackers.
If the option is on, the player can be distracted by tele-other attempts at awkward times, such as during difficult combat, so it is safer to leave accept aid off unless with trusted friends. Also Tele-other can be used for luring, which is a reportable action.
Players are still able to receive aid in multiway combat areas, even with accept aid off.
