This script manipulates the SCUM database for the single player mode to increase the level of all skills and attributes to max (or the value of your choice) for a given prisoner. This script does not work for multiplayer characters.
You can edit the configuration settings SET_ATTRIBUTES and SET_SKILLS at the start of the script below to change the target values for the skills and attributes. Default is maxed out.
Tested with SCUM Build 0.9.101.72873
