In the final update of 2018, Black Desert Mobile introduced new floors of the Learning Tower and a number of fixes which will be described below.
Increased the number of floors of the Learning Tower to 60. If you stick to the old calculation for passing all the floors you probably need 30,000 total GS. To check it will take some time and your screenshots. Screenshots with the passed floor and GS can be sent to the VC or to the Discord, to whom it is more convenient.
Reduced protection in PVP in an open field.
Increased protection of siege buildings and guns from 5,000 to 50,000.
