I am surprised at how little difference the Light spell makes, and the Night Eyes spell doesn't seem to do a thing. Guess I'm spoiled by Oblivion. Did anyone ever make a mod to improve these two spells?

Also, I've notice how your character always starts out at walking speed when loading a Quicksave made when you were running (also not like Oblivion). Did anyone ever try to fix that with a mod?

Uuh, if you don't notice a difference, I suggest checking the actual settings for your screen. Because as long as I play in full-screen, the light & night eye makes HUGE differences. However, playing in window mode decreases the difference they make (or the difference they appear to make). And yes, I've played Oblivion plenty, and I would say that the Morrowind night eye is way better, when you actually have got about 100 points in Night Eye.

Yeah...I'd also say check your settings. The default Khajiit Night Eye spell actually makes it TOO BRIGHT on my computers. Do you use any mods that darken the ambient lighting? That might contribute to your problem. At any rate, it's easy enough to fix. Either go into the CS and change the magnitudes or create your own spells in-game.

The "Spells" portion of my mod jacks up the effectiveness of the pre-made Light spells and lowers the cost significantly.

Their is a mod called "Night Vision" which turns everything green at night and requires/uses MGE shaders to make the effect work flawlessly. Also during the day if you turn it on, it blinds you. However, I thik it may be more of a cheat than a tweak but if you can somehow justify your character having a few special Avatar spells to begin with that no NPC has, this could be one of them. Their is no manna cost to cast but the mod maker says to change that in the CS to make it less of a tweak.
