Actually, you get thaumaturgy [-3], which gives free 2 focus items and 1 free specialisation for +1 power. 3 specialisations for +8 focus total (+5/+3) and another 3 specialisations for 12 enchanted items.
Lore 5 + 5 focus +1 specialisation for a total power of Legendary+++ (+11)
1 + 3 focus for a total of 4 uses each.
12 items at +11 strength, 4 uses each.
For defense you get one item at 11 strength 4 uses, one item at 10 strength for 2 exchanges 4 uses, one item for 9 strength 3 exchanges.
For offense you get 5 items for 4 disruptions, 4 physical attacks, 4 mind controls, 4 transformations. All Power 11.
For specials you get 2 items for 4 veils strength 10 duration 2, and 4 teleportations strength 10 duration 2 (20 zones).
You also get 2 potions of whatever you want of base power 11 which you invoke 2 aspects (or have a helper invoke them) to get power 15 and invoke an additional aspect when used for power 17.
Last but not least, you are still a full thaumaturgist with Lore 5, Lore 11 for crafting things like Golems via ritual. If you make and drink a potion of Lore before doing your thaumaturgy, you could raise your lore to 13 for enough time to do a Power 13 thaumaturgy spell. And you can still do slower rituals.
Yeah, that's a huge amount of stored magic. Unfortunately, you cannot adapt to the situation; your powers are prestored. But maybe that's something you have no problem with.
