From ECO - English Wiki

The collaboration settings on a server affect how quickly skill points are gained, how they are gained, and how many specialties players can acquire.

Specialty Costs[edit]

A server with a higher collaboration setting will require more experience points to earn the next Specialization Point, reducing the number of specialties a single player can obtain. The player always starts with a specialization point in Self-Improvement and one free specialization point. The experience values for each new skill point do not change after the 7th additional point and their values under the different collaboration settings are:

No Collaboration (1-3 players) Low Collaboration (3-10 players) Medium Collaboration (10-30 players) High Collaboration (30+ players)
