The tutorial zone. Bonfires, hidden shortcuts, and the three items most players miss in the opening 30 minutes.

The largest region. 6 bonfires, 3 optional bosses, and the entrance to the Sunken Palace. The rooftop shortcut is non-obvious.

Non-linear labyrinth. Every key item location, the hidden elevator, and how to reach the Skareth arena from two different directions.

Act III optional area. The Cinderbound Wyvern arena, 4 unique weapons, and the Pyre covenant vendor who only appears after Skareth.
