Ninja
From the RuneScape Wiki, the wiki for all things RuneScape
Ninja is a term commonly used in Clan Wars where a small clan will cause confusion amongst the other team, by taking chaotic routes all over the field. It involves a small group clan of usually 5 or less, when paired up with a larger clan. Its a tactic used by the smaller group where they choose a larger map to play on allowing them to remain hidden for a great deal of time. This then causes the larger enemy clan to break up, allowing the smaller clan to attack them one at a time, giving the smaller 'ninja' clan an upperhand. This tactic usually requires the 'ninja' clan to have Spirit terrorbirds or Energy potions allowing them to strike and run away which keeps them "invisible" for a longer period of time.
Above is an example of a "ninja route" that can be used by a small clan. With the blue circles being points of encounter with the enemy team.
