i still think a sixth level spell should not be capable of this. 11 level wizards creating permabuffs? Allowing for more spell slots with which to use better spells? You create a combat machine. Permanent Creations. Permanent Regenerations. Permanent Timestops. Think of the Permanent Timestops. Noone can dispell it but you. You have literally infinite prep time. Every wizards dream. (Okay, that last one has little to do with spell level, but still. Permanent Timestop=King of All Cosmos without using Epic Spells)
