Growth

Growing a character and raising different Attributes, Skills and Statuses is based on Experience gained at the end of each session.
Levelling Attributes and Statuses works by putting in XP equal to 4x the current score. For example going from 2 to 3 takes 8XP. Getting a Status from 0 to 1 uses 4XP.
Levelling Skills works by putting in XP equal to x3 the current score. For example going from 3 to 4 would take 9XP. Getting a Skill from 0 to 1 uses 3XP.
