Zones

Level 85 areas are the levels in D2X, v1.10+, in which the highest level items can be found from every boss monster. In PD2 some areas were changed to Level 85 areas to have more places to farm.

These are the TC 85 areas with the amount of monster types that have an immunity. Some monster types have multiple immunities and get counted for both rows. If it says 2 + 1 it means there are 2 normal monster types that spawn with immunities and 1 super unique. You may still encounter immune unique monsters as those have random immunities.
