Multicombat areas are identified upon entering by two crossed swords () which appear in the bottom right-hand corner of the interface or under the mini world map. Anywhere else is a Single-way combat area, also known as a single-combat area.
Multicombat areas are especially dangerous in the Wilderness, as a player can be attacked by more than one monster or player at a time. It is very useful, though, to be in a multicombat area while monster slaying with friends, as lone players can be killed easily.
Notice when you are using Magic or Ranged on an enemy behind a barrier, such as ranging goblins behind a fence, even though it's not a multicombat area, as long as you aren't under attack, you can attack more than one enemy.

Some weapons, spells or equipment are capable of hitting multiple opponents in a single hit. Most of them could still be used in single-combat areas, but they could only hit multiple opponents while in a multi-combat area. They include:
- Some Ancient Magicks:
- Chinchompas, Red chinchompas and Black chinchompas
- The special attacks of some weapons:
- The Retribution prayer deals damage to surrounding opponents on the player's death.
- The Void seal deals damage to all nearby pests when operated.
Technically, the Dwarf multicannon is not a multi-hitting weapon; it simply shoots at many opponents very rapidly given that the player is not under attack or is in a multi-combat area.
- Usually, when fighting a single monster with other players, the player that applied the most total damage at the end of the battle gets the monster's item/coin drop.
- Players can aggravate multiple enemies by simply attacking all of them without killing them then running to a farther location. The aggressive monsters will follow the player causing the monsters to pile the player.
- What determines if you are in able to attack someone else is based on the zone they are currently in, which means one could attack multiple from a single-combat zone as long as they are in a multicombat area. This will also mean that only one person can attack you if you are in a single-combat area.
