The Perfect World International team has posted a preview trailer for the game's Age of Spirits expansion on the official Web site. According to the post, this week's patch will contain a collection of features and updates from the expansion, but the genie system will be published within the next few weeks.

In Age of Spirits, players will now be able to zoom out their camera and cast buffs and heals on themselves when targeting hostile enemies. As for genies, which are the primary feature in Age of Spirits, they are non-combat pets that provide your character with new abilities to be used in both PvE and PvP.

For more information on the expansion, you can read today's patch notes here. Just remember the genie system has not been implemented yet.
