I know I am late, so I'm not going to promise 30 magic items. I am playing a verditious at the moment, so thinking of items anyway. I am not 100% good at this so please comment if I am doing anything wrong.
The helpful laboratory (ReTe, level 30)
This item gives the mage control of all the solid items in the room. The magus can tell an item to perform one action, and it will continue to do so until told to stop. Items will stir themselves, or be held in place when commanded.
(base 3, +1 touch, +1 concentration, +2 room) +5 levels, item maintains concentration, +10, unlimited uses
((does touch range work if the item is touching the room, or does it need voice for all the things in the room?))
Chariot of Helios (ReTE level 30)
A chariot of bronze, which when given its command will move as instructed, including flying through the sky.
(base 3, +2 metal, +1 concentration, +1 size, +1 moves quickly) +5 item maintains concentration, +5 34 uses per day
The useful gap (PeMe level 30)
This item causes the person targetted to lose the last ten minutes of memory.
