Insight Scroll

There are two basic types of Scrolls in Guildwars:

"Regular" Scrolls
These scrolls are Focus Items for Elementalists. These scrolls were renamed Earth Scrolls as part of the April 25th 2006 update.

Earth Scrolls are normally linked to the Elementalist Earth Magic attribute, although some collectors scrolls are linked to Energy Storage.

Insight Scrolls ("Rare" Scrolls)
This type of scroll provides an XP bonus to the whole party for a duration of time upon activation (by doubleclicking).
