Mega Scale Raids Guide
March 12, 2026
What mega scale Chambers of Xeric is and how our service helps you join organised raids for points and loot.
What are Mega Scales?
Mega scale raids are Chambers of Xeric (COX) runs with many players in one instance. More players mean better scaling: more points per hour, more efficient Olm kills, and a higher chance at uniques and pet. It's one of the most popular ways to farm COX for ancestral, kodai, twisted bow chance, and consistent GP.
Running mega scales yourself means organising a team, scheduling runs, and often waiting for fills. Our service lets you join organised raids without the hassle—you get your share of points and loot, and you can focus on other goals when you're not raiding.
Why use a service?
Organising and running mega scales takes time, a reliable team, and knowledge of roles. If you don't have a static or don't want to spend hours finding groups, our mega scale service is built for you. We run organised COX raids so you can join, get your points and loot, and leave—no need to organise, lead, or wait for fills.
Ideal for pet hunting, chasing uniques like ancestral and kodai, or simply getting consistent raid experience and GP without the overhead. Check our mega scale page for how to join and what to expect.
