Daybreak Game Company has laid out the details for the forthcoming Experience Vial System arriving with GU100 to EverQuest 2, a specially prepared update for All Access members. With experience vials, players can purchase an empty vial from the Marketplace for Daybreak Cash that can then be filled with experience. Once full, these vials can be used on an alt, given to a friend or sold via the broker.
Each vial has an XP Capacity that is required to fill it completely as well as an XP Conversion Rate that indicates the 'efficiency' of the vial. In the developer blog, a vial is shown that has a 60% experience siphon where 60% of XP earned through game activity will be placed into the vial.
Once you have filled up your Experience Vial, the counter on the vial will go up, indicating you have a filled vial to claim. In the case below you will note that the system auto-consumed one of my remaining empty vials and is continuing to siphon experience points.
You may now right click and claim your filled experience vials, which may be traded or consumed at your leisure. Experience granted from a vial works in all ways as if you earned it from a quest or defeating a creature, and thus will grant tithe, or can be converted into AA experience depending on how you have your experience slider set.
The blog goes into much more detail about the system, so be sure to head over to the EverQuest II site to learn more.
