Robe of the Mad Archmage

This plain dark gray robe, trimmed in silver embroidered sigils, bears no other decoration or imagery. This robe was once the possession of the Grey Savant, reputedly a mystic theurge of Boccob who supervised the Academy of Art and Science of Greyhawk. Upon his death, the school was renamed the Grey College in his honor and his magical robe passed to his star pupil, Zagig Yragerne. The robe of the mad archmage is an intelligent robe of blending that also grants a +2 bonus on rolls to defeat a creature's spell resistance and a insight bonus to your Armor Class and on all saving throws. Three times per day, you may cast a quickened spell of up to 9th level without increasing the spell level or your casting time. Spells already prepared or affected by a metamagic feat may not be quickened in this fashion. Finally, you may store up to 10 spell levels of spells in the robe, as a ring of spell storing.
The robe of the mad archmage's ability scores are Intelligence 18, Wisdom 10, and Charisma 18. It can speak Abyssal, Ancient Suloise, Celestial, Common, Draconic, and Flan, and it can also communicate telepathically. It can see (with darkvision) and hear up to 120 feet; it also has blindsense with a range of 120 feet. A personality conflict occurs any time you attempt to remove the robe to don another magical garment. The robe of the mad archmage's alignment is chaotic neutral, and its primary emotion is a curious longing, typically directed at magical treasure or arcane lore.
