Welcome to the endgame
The campaign was the tutorial. The Atlas is the game. Pick a tile to jump in: each one is a short page, no endless scroll.
The Atlas was fully reset: 300+ nodes, no respec, 3 Atlas Masters. Finish your first tower and a Precursor Fortress rises. The new apex is the Arbiter of Divinity; the old Arbiter of Ash was demoted to a Fortress gateway. Breach and Delirium were reworked. A few exact node names and boss HP values still need an in-game / poe2db check, flagged on each page.
Atlas sections
Getting started
From the Map Device to your first Fortress. Sustain, and what not to do yet.
Waystones
How maps work: tiers, revives, XP loss, tablets, and the mods to skip.
Atlas tree
Rebuilt 0.5 tree, the 3 Atlas Masters, and the pickup order for a fresh map.
Mechanics
League content deep-dive. Breach and Delirium reworked, the rest still core.
Pinnacle bosses
Arbiter of Divinity (apex), Xesht, Tangmazu, the Bodach, and how to reach them.
Citadels
Iron, Copper and Stone beams. Crisis Fragments and the Arbiter of Ash gateway.
