Revelation Online's Aptitude System Detailed

The way that Revelation Online is set up, it will reward you for having a certain...Aptitude for it. As you perform any action that grants experience, you will accumulate Aptitude up to a certain cap. Depending on your level, that Aptitude can then be spent to earn additional experience. If you don't happen to spend your Aptitude by the time your character's reservoir is full, it will be stored at an NPC named Mora Zin in Sulan and Sidus Ur.

There is, however, a daily limit on the amount of Aptitude you can receive in one day. You can get around this limit by paying for more with Ausgyth Points. The Aptitude you buy will then be put in "a special flask" on the Aptitude window. The reason that this system is in place is so that players who are unable to play regularly "do not miss out on the daily aptitude."
