Raids

A group of players fighting together in the Chambers of Xeric raid.

Raids are group activities in which the goal of the player(s) is to defeat several mini-bosses before reaching the final boss of the raid to claim their rewards, which include multiple best-in-slot equipment in the entire game. Due to the high-level nature of raids, players are usually required to bring all forms of combat to successfully clear the instance, and may also be expected to utilise different non-combat skills and solve various puzzles.

All raids take place in an instance, with the Chambers of Xeric (barring Challenge Mode) having a randomly generated arrangement. All three raids have a hard mode variant to them, and the Theatre of Blood and Tombs of Amascut both have easier, entry mode variants as well.

Raids scale based on the team's numbers and skills. In the Chambers of Xeric, the team's overall skill total determines what resources can appear and the requirements to complete some puzzle rooms. In all raids, having more people increases the enemies' stats - health, combat or both.

Raids can be identified with a brown star icon on the map.

List of raids

There are currently three raids, the Chambers of Xeric, the Theatre of Blood, and the Tombs of Amascut. Each one features its own unique mechanics that make the three raids very different in practice to one another, with different balances of combat, puzzles, and skilling encounters, as well as different amounts of customisability and difficulty levels.

Raid	Date Released	Description	Requirements	Unique Mechanics
	5 January 2017	Explore a large cave system underneath Mount Quidamortem built by Xeric.	N/A	A randomly generated arrangement of combat and non-combat encounters mean each raid is different from the last. Up to 100 players can tackle the raid at once, with the amount of players beginning the raid determining the enemies' strength. Players will fight their way through two floors of enemies before a confrontation with the Great Olm, the final enemy of the raid. Challenge Mode is also available for players wishing for a harder encounter, with all twelve potential rooms being presented in a set order.
	7 June 2018	Survive the blood sports of the vampyres in Meiyerditch.	Priest in Peril	Unlike the other raids, the Theatre of Blood features only combat encounters, with five mini-bosses leading up to the confrontation with Verzik Vitur, currently the strongest monster in Old School RuneScape. The Theatre of Blood includes a Hard Mode as well as an Entry Mode. Entry Mode is a beginner's introduction to the raid with the mechanics made more friendly for them, albeit at the cost of less rewards and no chance of obtaining rare rewards. Hard Mode is offered for players who have completed the raid at least once in normal mode, modifying the bosses' mechanics to make them more challenging.
	24 August 2022	Fight your way through Amascut's thralls inside the Jaltevas Pyramid.	Beneath Cursed Sands	A unique invocation system allows players to scale the raid to the difficulty level of their choice, by selecting which challenging mechanics they want to tackle, which determines the raid's difficulty, presented as Entry, Normal and Expert mode. These invocations range from inventory restrictions to additional or modified special attacks from the bosses, to time and respawn limits. Additionally, players can choose to attempt each of the four mini-bosses and their respective puzzle rooms in any order they wish, with the four paths of the raid stretching out from a central nexus, before they can unlock the lower level where they can face the final bosses, Tumeken's Warden and Elidinis' Warden, also in the order they choose.
