Okay, here's how I'd do all that:
Armored Coat [6 shift Block or Armor: 3, 7 times per session](4 Enchanted Item Slots)
Laser Wand [Weapon 6 Attack targetted with Discipline, 3 times per session] (2 Enchanted Item Slots)
Telekinesis Bracelet [6 shift Maneuver used as Might, 3 times per session] (2 Enchanted Item Slots)
Magical Grenades [Weapon 4 Attack against an entire Zone targetted with Discipline, 3 times per session] (2 Enchanted Item Slots)
Veil Ring [4 shift Veil (no penalty to see out), 3 times per session] (2 Enchanted Item Slots)
4 potion Slots.
That's 16 Item Slots, which will require Thaumaturgy [-3], and Refinement [-3] invested in Item Slots.
Thinking about it, with that setup, you should drop to two Item Slot Refinements and buy Refinement for Specialties once, for a total of +1 Strength, +2 Frequency for Crafting Specialties. That'll drop the cost of all 5 items by one slot, and leave 5 slots for Potions.
