If you are interested in contributing to the data for bosses, please see the top of each boss page to access the collected data for the boss.
Bosses are battles in which multiple players can attack the same target. These battles usually last multiple days in which the players spend their stamina to attack the bosses. Killing a boss rewards the player with many pieces of awesome loot, depending on how many 'points' you earn. There are also a number of Achievements that can be earned by killing bosses.
The bosses can be accessed by tapping on the stamina icon and selecting one of the boss options; boss list or summon boss. Once in the bosses screen, the 'Yours' tab shows any bosses that you are currently taking part in.
The 'Public' tab shows other players bosses which you can join. Specific bosses can be joined with a boss code, or you may select bosses in the list which will display all of the current public fights for that boss. Be aware that only bosses appropriate for your level will appear in the list. Higher level players will not have low level boss fights appear in their public list, making them only joinable via boss code.
Finally, the 'Create' tab shows a list of all the bosses that you can summon.
Legend Bosses have three summoning requirements: a cell phone, a passport, and having earned at least a 2-star rating on an associated boss. Even those who attempt to join an existing Legends boss must meet the latter two requirements. The passport is consumed when joining the battle.
Most boss battles have a number of stages, with one or more foes in each stage. Each foe has a class (see below). You can choose which enemy to attack, how much stamina to spend and whether to use a normal attack or the special attack from your class. The enemy will do damage to one of the people attacking it if it survives your attack. Once an enemy is down to a certain level of health, you will have the option to execute them.
The following lieutenants have powers that specifically affect boss fights:
When joining a boss fight, you must choose a class for that battle. Each foe you meet also has a class. If the tier 2 class is unlocked, entering a boss fight as the base class will earn XP for the tier 2 class as well. (example: Attacking as an Enforcer will earn XP for the Titan class). This tier 2 class XP can be enhanced by having Fleur seated.
Every 10 stamina spent while using a class will grant 1 XP towards the tier 1 class.
Every 200 stamina spent while using a class will grant 1 XP towards the tier 2 class.
Certain classes do additional damage when they use their class-specific attack against certain other classes:
- Enforcers do extra damage against Assassins.
- Assassins do extra damage against Heavy Weapons.
- Heavy Weapons do extra damage against Snipers.
- Snipers do extra damage against Enforcers.
