Running Princes of the Apocalypse: Elemental Evil Campaign Tips

Quick answer

Run Princes of the Apocalypse by treating the four elemental cults as a living web, not four separate dungeons: seed rumors early, let player choices reshape which temple they hit first, and keep the prophets as recurring threats rather than final bosses you rush toward.

Your step-by-step prep plan

1. Read the cult overview before the dungeon maps: Skim the four cult descriptions and each prophet's motive first. Write one sentence per cult explaining what it wants and who it distrusts. Common mistake: starting with room-by-room maps, which buries the faction logic under encounter text. Checkpoint: you can explain each cult's goal in one sentence without opening the book.
2. Seed two cult rumors in the first session: Drop two contrasting rumors: one about a cult's public charity front, one about a rival cult's sabotage. Let the party pick which thread to pull. Common mistake: revealing all four cults at once, which flattens the mystery. Checkpoint: the players have named at least one cult themselves.
3. Choose your temple order before session three: Decide whether you are running all four temples, two, or one plus off-screen pressure. Write the order and the reason each temple follows the last. Common mistake: letting the party wander into a temple you have not prepped because you assumed they would go elsewhere. Checkpoint: you know which temple is next and why.
4. Prep one temple at a time, not the whole book: For the next temple, note its entrance, its prophet's reaction to intruders, and two ways the cult can respond after the party leaves. Common mistake: prepping every room in advance and burning out before the climax. Checkpoint: your notes for the next session fit on one page.
5. Run prophets as recurring faces, not boss fights: Have each prophet appear in person or by proxy at least once before the temple confrontation, and give them a reason to retreat or bargain. Common mistake: saving the prophet for the final room, which makes them feel like a stat block instead of a villain. Checkpoint: the party has a personal reason to want one prophet stopped.
6. Close each temple with a consequence, not just loot: After a temple falls, show what changes: a rival cult gains ground, a faction like the Emerald Enclave asks for help, or the elemental threat shifts. Common mistake: treating temple completion as a reset button. Checkpoint: the next session opens with a visible change caused by the party's victory.

Product facts

• D&D RPG: Elemental Evil - Princes of the Apocalypse: The book presents four corrupt prophets who each command a cadre of cultists and creatures building four elemental temples. That structure gives you four ready-made faction leaders and four location arcs, so you can prep one temple at a time instead of the whole campaign at once.
