*The robe is a Robe of the Archmagi. Now, those usually have a colour of black, grey, or white, but he can't help but noticing that it's a sort of off-black dark purple affair. The analysis indicates that some combination of Elayna Valsice going Neutral and trying to refix her Robe to not give her negative levels but never finishing combined with Wild Surges has left it at a point where it is neither colour. It gives one negative level to Neutral and Evil wearers and still three to Good wearers. For a small price, it can probably be fixed in either direction, but it will still always be a ladies' dress/robe for female mages.*
*The spiraling coiling sapphire thing is a very classy personal spell nexus that has apparently been safeguarded and connected to one particular mage's energies and casting style. It also has some sort of Misdirection magic that prevent the Identify from determining more details--stronger magic is required.*
*The orb is a modified Orb of Storms that ostensibly can attempt to control aether storms and temporal aspects as well as usual weather, though it doesn't have the whole Storm of Vengeance thing. There is an unidentifiable quirk in the item due to wild surges. For a small price, it can probably be fixed.*
*The skull-tipped rod is a Lesser Necromantic Nexus. You can cast necromancy spells into the nexus, one each of levels 0, 1, 2, and 3. You can then substitute any spell of those levels for the spells stored in the nexus (this does not expend the nexus spells, but it does expend your spell slot) as long as you are holding the nexus. Whenever you cast the spells stored in the nexus, the DC increases by 1. Also, you can cast the spells stored in the nexus as if they were the subject of the Still Spell feat 3/day. There is an unidentifiable quirk in the item due to wild surges. For a small price, it can probably be fixed.*
