I reached level 2 and got 2 attribute points. 1 skill slot = 2 Memory points. I don't know if there is such a thing as equipment with +Memory, but I would bet against that. I don't know if the amount of attribute points per level increases, but I don't expect that either.
Seems like Mages will need to alternate their attribute points each level between INT/Whatever and Memory. And we haven't reached a point where some spells cost multiple memory slots.
I'll have to play a mage for some time to decide how well this works.
