Yeah, it's possible to get over 300 magicka, but you'd probably need to be a breton or high elf if you wanted to do it without enchanted items. Not sure though. You might just need really high intelligence (like 90-100) if you are another race. And as paralyze goes, for 5 seconds, you will probably need to be at least Expert in Illusion, if not master.

One more thing...

Choose either the Mage or the Apprentice as your birthsign if you are going to primarily be a spellcaster and need the magicka.

Cool summons = 500 magicka? Then you're looking in the wrong place my friend. I believe as a master of conjuration my summon dremora lord for 30 seconds spell is about 110 magicka, which is all oyu really need considering the battle will either be over by then, or your summon will have been killed, thus wasting a lot of mana.

If you are not a Breton or a High Elf, and don't have a birthsign that conferes any magic boost at all, then your max mana is 200. (1 intelligence point is 2 magicka). However this can be solved too with enchantments. I think without temporarily fortifying with spells, it is possible if you do everything perfectly to get about 1020 magicka semi permanently.

I think the only paralyze spells available for sale are 3 second sand 10 seconds. If you want a 5 you'll have to make it, and you'll probably need to be a master of illusion for it.

Sorry for spelling/grammar mistakes.
