Here's a closer look at some Entity Researchers XP data and Mission requirements. The Experience curve for leveling has changed considerably over time, Levels 1-30 remain the same but the later game became a grind. As you can see below XP required from level 30 onward is reduced significantly.
Experience curves for Level 1-50 Entity XP yield has increased by around 10%, though as you level up the XP will reduce accordingly, Casefile and Elite entities drop a little extra XP increasing by around 15%. As many entities will be capped to their maximum level, XP gain slows in the later levels further compounding the grind in the previous XP curve. This could be somewhat mitigated with +XP Up Unique items though this modifier is quite rare for dropped Uniques leaving this option dictated too much by chance. As Missions are compulsory to the completion of the main Entity Researchers narrative more players should now reach the final group of Missions. Below you will find a list of Missions and individual Level requirements: Lvl 10 - 01: Entities Aquatic 16 - 02: Masks Off 22 - 03: Burning Belief 28 - 04: Overload 35 - 05: Illumination 42 - 06: Body Snatchers 48 - 07: Last Known Location 52 - 08: The Sunken Ward 55 - 09: Dark Times (Complete Dark Times) 10: The Grand Opening Drop a comment if you would like to see anything else covered in further posts.
