Bountiful Bags

Bountiful Bags was a guild perk granted at guild level 23 that increases the amount of materials gained from Mining, Skinning, Herbalism, and Disenchanting. This functions by providing a chance to get an additional set of materials from these professions. The extra materials will show up as an additional stack of materials in the loot window. The perk only affects common materials such Elementium Ore and Whiptail, and will not grant extra stacks of "bonus" materials like Volatile Life.

On release, the perk unintentionally granted a chance to gain additional keystones from archaeology, but this has since been fixed and Bountiful Bags no longer has any effect on any secondary professions.
