So far I have obtained the master conjuration, illusion and destruction spells and with the exception of conjuration, I have been very disappointed. They just don't seem at all practical and in the case of destruction they are far too weak.

What do you think?

I am not fond of them. Not a lot of variety or use.

i like the master spells. especialy those from alteration, destruction and the permanent summons from conjuration. there could be more variety though. also the destruction spells didn't seem to be very strong.
