Area Levels

The monster level of each area in Classic, in Normal, Nightmare and Hell. Indented names are dungeons and sub-areas of the area above them.

In Classic, Nightmare is always Normal plus 25 and Hell is Normal plus 50.

Unique monsters are 3 levels above the area level, so the three seal bosses in Hell Chaos Sanctuary are level 81.
These are minimum levels. Some normal monsters spawn higher than the area level shown.
Monster level sets the item level of drops, which decides which items and affixes can drop. See Affixes.
