Here are some ideas on pieces of gear you could add, these would be the level 29 versions... I am not quite sure how they could look if scaled down to lower level. Anyhow, I searched through item attributes for quite a while before I ended up with these.... I spent about two and a half hours coming up with all of these and feel they would fix the complaints on the set piece selections for the Adherents Of the Mist set choices. Please give criticism where needed and perhaps make your own suggestions and thanks in advance.

6) Sentient Bracers (bracers)
Feeding these bracers named items has a chance for them to randomly take on individual attributes from said named items, otherwise this item is blank, the sentient stone embedded into these bracers is slightly damaged and can not be removed. Feeding it a copy of itself will remove the last enchantment successfully gained. Five enchantments max! (Item does not accept filigrees). The highest level piece of gear this takes an attribute from determines the minimum level attached to it.
