Introduction

Chambers of xeric, also known as Raids 1 or CoX, is a minigame that provides high tier equipment and weapons. Most players play this minigame for a chance on the twisted bow.

The goal is to kill all bosses, you can do this solo or in a group of players. If you play in a group, everyone will get rewarded by a key (2 keys if kronos is active).

After killing olm, the final boss, you have a chance of receiving a rare key, but most of the time you'll receive a common key. The droprate of a rare key will be explained later on.

Requirements

1500 total level for normal modes.

750 total level for rogue modes.

Mechanics

Use the command ::raids to get to the lobby. Here you can enter solo or make a group.

You run though the minigame and kill every boss you see, these are always the same bosses, but in random order.

Here is a list of the bosses and which prayer to use against it:

  • lizardman shaman (x3) (pray melee)
  • skeletal mystic (x3) (pray magic)
  • vanguard (x3) (pray magic and melee)
  • vasa nistirio (pray magic)
  • ice demon (pray melee)
  • muttadile (pray melee)
  • tekton (pray melee)
  • olm (pray range)

Supplies

The player who deals the most dmg to a certain boss receives the drop of the monster.

This drop has a chance to contain food and overload doses, these overload doses can only be used inside cox.

Drop Rates

Which drop rate you get below is determined on the damage output that you do in the whole raid - you will be told at the end of the raid which position you came.

Minimum damage to receive a key from Raids is 550.
