Single-way combat

A Single-way combat area, also known as a Single combat area, is an area of the RuneScape world where a player or monster can be attacked by only one player or monster at a time. Most areas of the world are single-way combat. Those that are not are Multi-way combat areas, where a player or monster can be attacked by several players or monsters at a time. Multi-way combat areas are identified by an icon of two crossed swords which appears in the top right hand corner of the interface or under the mini world map. If this icon is not present, then the area is single-way combat.

Summoning familars cannot assist the player in combat in single-way combat areas, since a player and the familiar both fight one enemy.

Dreadnips, which are not familiars, can fight the same opponent as the player in a single-way area. Similarly, a Death spawn called up by a Nechryael in a single-way combat area can fight the same opponent as the Nechryael.

Trivia

 * Jagex's official terms are 'single-way combat' and 'multi-way combat', as can be seen in the monster fight conditions in the Dominion Tower. However, 'multicombat' and 'single combat' are more commonly used by most players.
