Use offline training

Every night all premium players should put all of their character to train offline. The gain is rather small but over time it adds up. If you have characters just sitting offline, take them to a training statue. If you have access to beds, mages can benefit the most sleeping in beds, with the additional mana and soul points. If you plan on creating new characters, e.g. in another world or of another vocation, it is a good idea to start now to get a few weeks/months of training under your belt.
