What Are Legion Gathering Events?
Legion Gathering Events are a special kind of event in Diablo 4 known as a Region event. These events are intended to be completed by a group of players and are typically too hard to complete alone.
During a Legion Gathering Event, players fight waves of demons culminating in an Overlord.This event is timedand, depending on the number of players, can be very difficult to complete at the mastery level.

Diablo 4’s Paragon Board offers a ton of customization for players after max level, but it can be overwhelming without guidance.
Finding Legion Gathering Events
When a Legion event is preparing to spawn, a circular icon will appear on the map. You will have approximately 5 minutes to arrive at the location of the event from the time the icon pops up to the time the event starts. You can join this event late, but only for a few seconds after it begins.
There are several Legion Gathering Events locations, which are chosen randomly each time the event happens.Some locations are over a Stronghold,meaning you’ll need to have completed the Stronghold to participate. Known places that a Legion event can spawn are:

The game’s development team has expressed the desire to add more Zone events, so more locations may be added in the future.

How Often Do Gathering Legion Events Spawn?
These events are much more common than World Bosses, who spawn every six hours. Instead, players can expect to see a new Gathering Legion Event pop upevery 30 minutes.Players that want notifications about World Events such as the Gathering Legions can followDiablo Paragonon Twitter.
How To Use Campfires In Gathering Legion Events
You may notice that when you arrive at the spawn of a Gathering Legion event before it begins, there is a small campfire in the middle of the area. These campfires can be stoked (by interacting with them) to boost your experience gained during the event. This is presumably a reward for early arrivals to offset the fact that players can join a Gathering Legion Event late.
The possible experience boost from a campfire ranges from 1-15%. The buff you earn depends on how long you are standing next to the campfire before the event begins. The longer you are next to the campfire, the higher the buff, and whatever number you land on when the event begins will stick with you for the duration.

While this XP bonus did not stack with Elixirs at launch, recent patches have changed this. As a result, it is possible to reach a total of +20% XP by consuming an Elixir and standing next to the campfire.
How To Complete A Legion Gathering Event
Legion Gathering Events, likeWorld Bosses, are meant to be cooperative MMO-esque events. While it is possible to complete a Legion Gathering Event solo, it is not recommended.
To complete the event, players will need to:
The remaining time can be viewed under your mini-map on the right-hand side of your screen.
Gear & Consumables
Because the timers can get pretty tight for this event, it is suggested to arrive with a few key pieces of equipment.
Timers For Each Wave
Each wave is timed separately, with a new timer spawning at the beginning of each phase. The timers for each section of the event are:
First Wave
First Servant of Hell
Second Wave
1 minute 45 seconds
Second Servant of Hell
Third Wave
1 minute 30 seconds
Third Servant of Hell
45 seconds
The Overlord
Defeating The Overlord
The Overlord is a reused Boss from somewhere else in the game. These are typically bosses from Side Dungeons rather than main story content. Unlike their solo-play counterparts, Overlords have greatly increased health and damage. Known Overlords include:
When fighting the Overlord, familiarity with the game’s optional content is your best friend, as all Overlords share the mechanics of their weaker counterparts.

Rewards For Legion Gathering Events
Players who complete Legion Gathering Events will receive several rewards. Like local events, there are two tiers of completion - standard and mastery. Forstandard completion, you will receive 3 Radiant Chests, while formastery completion, you will receive 3 Greater Radiant Chests. This loot is instanced, meaning each player gets their own.
Radiant chests dropgold,gear,Murmuring Obols,crafting materials, andgemswhen opened. While Legendary items are not guaranteed from Radiant Chests, there is a significantly higher chance than when opening a regular chest.
Additionally, the Greater Radiant Chests that spawn from Gathering Legion Events have a small chance to contain Legion-specificcosmetics and gear.
At this time, Seasonal Loot will not drop from Legion Gathering Events. This is because the spawning rules for the event override special enemy spawning and chest drops.
Cosmetic Drops From Gathering Legion Events
Data on which items drop from Legion Events is still incomplete. However, there are several confirmed drops:
These mounts appear to drop as a random chance on a loot table, so your success in collecting them may vary.
