Map boss

✍️This article is a stub. Please help improve the article by expanding it.

A map boss is a type of map encounter that can occur in a map which adds a difficult unique monster. On the Atlas, locations with map bosses are marked with an icon. Maps without this icon will not have a boss appear.

Each map area has a specific boss that will appear if the map contains a boss. The combinations can be found in List of maps.

Mechanics

In maps containing a map boss, the map boss must be defeated for the map to count as completed.

Map bosses have significantly increased monster item rarity and quantity. Most bosses are versions of bosses from the campaign, though they may have modified or new skills or different arenas/arena hazards.

Map bosses are guaranteed to drop a rare item. In addition, as unique monsters, all items they drop will have an item level 2 levels higher than their monster level. Waystones dropped by final map bosses are always one tier higher than the map you are in. Final map bosses also have a base chance to drop a waystone that scales down in higher tier maps; this chance is affected by modifiers to waystone drop chance.

In parties, when fighting a map boss or pinnacle boss, only the map owner can respawn the full party simultaneously, if they have respawn attempts remaining. Doing so will restart the boss encounter from full life.

If a player rushes to a map boss, dies, and respawns, all monsters other than the map boss and all other encounters in the area will be removed.

Tooltip

Area has +1 to Monster level.

With the Organised Forces notable atlas passive allocated, areas with map bosses are Irradiated, increasing the monster level of all monsters in the area by +1.

Citadel boss

Citadel bosses, sometimes referred to as uber act bosses, are special map bosses based on the act bosses of the campaign: Count Geonor, Jamanra, the Abomination, and Doryani. Citadel bosses drop Crisis Fragments, items used to access The Arbiter of Ash, the pinnacle atlas encounter.

Version history

Version	Changes
0.2.0	Once you start a Boss fight, the respawning system will change to require the map owner to collectively respawn the entire party. This is so that you must still kill the boss from full life. If you decide to rush to the Map Boss without interacting with any of the other Map content and then die, you will respawn at the Boss checkpoint and only the Map Boss will be present. All of the other monsters and content will be removed. This is to prevent cases where players would be able to farm multiple copies of the same rewards by dying on purpose. Tower Maps can now spawn with all extra content mechanics, including Bosses. Waystones dropped by Final Map Bosses will now always be one tier higher than the map you are in. Final Map Bosses and the final naturally-occurring Rare Monsters in Tier 1 maps have a 100% chance to drop a waystone. This chance scales down as you get into higher Map Tiers, but will still be guaranteed with appropriate investment into Waystone Suffix Modifiers and through the Atlas Passive Tree. Natual waystone drops have been reduced to compensate.
0.1.1	Added the new Overseer's Precursor Tablet, a currency item which can be placed in completed Towers to add Map Bosses to valid Maps in radius. These tablets drop from Map Bosses, and can roll exclusive modifiers that affect Map Bosses. Adjusted the chance for Maps to contain Bosses, you should be encountering a Boss roughly every 1 in 4 Maps. The chance for Map Bosses to drop a Waystone of the current tier or higher has been reduced to account for the increase in total number of Map Bosses.
0.1.0	Introduced to the game.
