Guild bonus

A Guild bonus stacks with other bonus types but not with other Guild bonuses. A character can have a Guild bonus applied to a skill, ability or many other game variables (damage, to-hit, saves, resistances etc.). A Guild bonus will come from one of two sources:
 * Airship Amenities
 * Guild Augments

Airship Amenities
Many of the new Guild Amenities introduced in Update 22 are now specified as being a Guild type bonus.

Guild Augments
Although items with Guild Augment slots no longer drop since Update 17, there are many still in use and some can occasionally be found for sale on the Auction House. Guild Augment crystals can be purchased from vendors in House Kundarak.
