Piercings.json configures what demands father will place upon you. 

You can add or remove entries from the various levels to adjust his demands for that level. A level should have at least one more demand than the last level. And include all of his other demands up until then. Accepted values are in the list of 'int' values (except 'maxlevel').

You can even increase/decrease the number of levels by adding/removing entries and modify 'maxlevel'.

Do not modify the int values (except 'maxlevel') unless you know what you're doing.

Recommend that level 1 always includes earlobes as the dialogue won't match otherwise.
