Oh, so now I put a paralysis effect on my shock spell. Oh okay.
No, not really. Paralysis was much too expensive and combining it with shock, which was also very expensive (presumably because it was the least resisted type of elemental damage), would make for a very low-damage spell if you wanted to have any hope of actually casting it without crazy amounts of fortify int or fortify magicka. What you quite possibly would do is combine with weakness to shock, blindness, calm, or damage attribute.
Or combine water breathing with swift swim. Gee, art like this should be on a museum!
Why bother with swit swim? I'd personally rather add more night eye since torches and the like doesn't work too well under water. Then again, I usually CE'd water breathing and a ton of NE, since my monitor back then was an old CRT with very faded colors and brightness. Couldn't see anything unless I turned up the light to crazy levels.
Well, how about merely having the ability to make spells that suited the situation? Increase damage at the cost of needing to go into touch range? Or keeping it a ranged target type spell but turning the AoE way down, effectively making your spell a single target sledgehammer? How about having the freedom to build the spells you found suitable? How about slowly but surely killing Gaenor by constantly spamming slow damage strength spells until they'd punch through his Reflect-layer and, due to his full suit of ebony, root him to a single spot permanently? How about making customized summon spells with half the duration and a *much* more agreeable magicka cost?
There were plenty of funny things you could do with magicka in Morrowind and if gamesas hadn't totally gutted magic and removed spell creation on top of that, there'd be just as much fun with it in Skyrim. More, actually. Touch, bolt-type, ball-type, or sustained jet. More ways to deliver the effect = more options = more variety = more fun. Can you really tell me with a straight face that you wouldn't like to use a poison jet in one hand and a freeze jet in the other? That you wouldn't like to throw balls of exploding thunder after bandits? That you wouldn't enjoy having a high damage, short range flame thrower as a late game anti-draugr measure, rather than the short damage, short range flamethrower the game gives you? Really?
