Game data updates to the wiki have been started.
A system has been added that will automatically add divination cards and other items to the item acquisition sections where appropriate. Entries added by this system will be shown as automatic in the item acquisition section.

Some further details on what needs to be done can be found on Path of Exile Wiki:To-do list/Automatic upgraded from and issues can be posted on the talk page.

It grants a chance to generate a power charge if you or your totems kill an enemy or place a totem, as well as a chance to generate an endurance charge whenever a power charge is gained. It also grants elemental damage reduction while having an endurance charge and elemental penetration while having a power charge.
