Instance

From Old School RuneScape Wiki
Jump to: navigation, search

An instance is a special area, typically a quest area, that generates a new copy of the location for each player or group that enters the area. Players cannot see other players in instanced areas unless it's a group instanced area—in which case, the group cannot see any other groups.

Instanced areas can take place in entirely new areas that cannot be accessed without the instance or in areas that are normally not instanced. Most non-quest boss instances will require the player to pay a specific sum of money or have an item in their inventory access the instance.

Generally in an instance, dropped items persist for 30 minutes before despawning.

Examples of instanced areas[edit | edit source]

Boss instances[edit | edit source]

Some bosses have an instance option (sometimes called "custom session" or "custom encounter"), which may have a setup or entrance cost (coins or an item). Instances also share the requirements of the boss. The cost varies per instance and are shown below. Some instances offer an Item Retrieval Service, should the player leave the instance by death.

Slayer instance-like sections[edit | edit source]

Some bosses may only be slain if on a Slayer assignment, namely the Kraken, Thermonuclear smoke devil, Cerberus, Abyssal Sire, Grotesque Guardians, and Alchemical Hydra. In essence, some of these bosses' lairs seemingly function as if they were instances since while others can still enter and possibly crash, they're blocked off from being killed to the rest of the players who aren't on task.

Additionally, Dagannoth Kings have a Slayer lair, which is accessible on the Kings' ladder. Players who are on task may kill the kings for the duration of their task and can return upon death to retrieve items.
