Guild Crafting

Overview
Guild augmentation is like enchanting your gear – you need specifig gear that has a augment slot (tiny, small, medium and large) and the guild you are in is high enough to use that augment crystal(10, 25, 45 or 70). If you have the stuff needed you have to jump over to House Kundrak and find the suitable augment crystal vendor. Each size has its own vendor.

Once you purchase the right item and want to attach the crystal to your equipment item – head over to the Marketplace Stone of Change and stick them both in there and fire away. Soon the augmentation process will be complete and your item will have a stat/skill boost on it that stacks with everything.

The crystal will last for 6 hours after which it will disappear and you’ll have to reaugment it (and rebuy the crystal aswell). You can see the applied stat/skill boost in your character slot, usually marked as enhancement bonus. Note that the augment crystal bonuses don’t stack – if you are wearing two items that both have a +power crystal in it – only the highest applies.
