How the list works
The game files assign every act its waypoints and mark a boss at 21 of them. The list follows that: 17 boss encounters and four Keywardens, act by act in waypoint order. Each card names the boss the way its Adventure Mode bounty does, with the encounter from the boss window below – Rakanoth, for example, waits in "The Library of Fate" and Cydaea in "The Maiden of Lust". Then come the objective from that window, such as "Defeat Ghom, the Lord of Gluttony!", and the waypoint the boss is listed at. All 17 bosses are also available as bounties.
How much the bosses can take
The monster data gives every boss a life multiplier – a multiple of the base life of a monster of the same level; difficulty and rift level come on top. Malthael leads with 135, followed by Adria and Urzael (100 each) and Diablo (85). At the low end of the story bosses are Cydaea (30) and Zoltun Kulle (32); the Keywardens sit at 19 to 21. For comparison: Rift Guardians have 43, most normal monsters 1. The cards also list the damage type – Queen Araneae deals Poison damage, Zoltun Kulle and Adria Arcane damage.
Waypoints in Adventure Mode only
Three of the boss waypoints only exist in Adventure Mode: Caverns of Araneae (Act I), City of Caldeum and Temple of the Firstborn Level 1 (both Act II). All others are available in the campaign and in Adventure Mode; the client lists some of them twice for that, such as The Royal Crypts or Gardens of Hope 2nd Tier. The cards note the three exceptions below the waypoint.
Keywardens and Uber realms
The four Keywardens have fixed waypoints: Odeg the Fields of Misery (Act I), Sokahr Dahlgur Oasis (Act II), Xah'Rith Stonefort (Act III) and Nekarat Gardens of Hope 2nd Tier (Act IV). There are four Uber realms: the Realms of Regret, Putridness and Terror plus the Realm of Fright with Diablo. Their objectives only name the enemies by epithet, such as "the King of the Dead and the Merciless Witch" or "the Soul of Evil".
More encounters
Story events open a boss window too: saving Deckard Cain, Adria's Prison, the Battle for Heaven or breaching the Pandemonium Fortress. On top come the four events around Eirena, Shen, Lyndon and Kormac, Greed's Lair and the Echoing Nightmare, which the client knows in five versions with their own scenery. One rule applies to every encounter: the party only teleports in once everyone has accepted.
