First of all I'd like to thank the SDA crew, secondly RealityO and all the other forum posters for their advice and words of encouragement, and Risme for his ideas. After I had submitted my first Nox speedrun, I started to have second thoughts about the quality of my run, mostly because of poor planning. I quickly planned a better route, did a few practice runs, and managed to improve the old run by 10 minutes.

Comments for each segment:

1) Chapter 1 & 2
One thing to note here is that when Horvath the Archwizard steps out to save you from the urchins, the time it takes him to dispose of the urchins is completely random. They will throw rocks at him, which causes him to interrupt his spellcasting.

3) Chapter 4.
This is where things start to get interesting. I use the swap position spell in 3 locations to skip entire areas, a simple trick but a huge timesaver, one which I use several times in this speedrun. The first fight with the necromancer can be quite tough, but I found that you can just take cover behind a mana pylon while channeling lightning on him, while he is unable to retaliate because he needs to have a clear line of fire. Against the warrior I spam sulfuric flares to force him to stand in place and block, while standing in a burn spell. As for the mage, I found that he usually teleports between 2 fixed spots every time he takes damage. If you place a burn spell on the teleport locations, and then damage him once, he will teleport back and forth between the 2 burns, constantly taking damage.

4) Chapter 5 part 1.
This is the first chapter that I split into 2 segments. Not because it's a long chapter or anything, it's just that the trick I use to skip an area is veryhard to pull off.

5) Chapter 5 part 2.
Here I use magic missiles to lure an ogress out of her house to use swap position with her, in order to skip going through a long underground tunnel to get to the ogre boss. This trick works very rarely, which is the first reason for splitting this chapter into 2 segments. After defeating the ogre boss I'm supposed to escort Horvath out of the ogre village safely. The second reason for using 2 segments for this chapter is that I just leave him to fend for himself. Most of the times he'll just die, causing me to fail the mission, but once in a while he'll stay alive long enough that I manage to exit the area, causing him to teleport to the next area with me.

6) Chapter 6.
In this segment I use lock to prevent some of the warriors from following me. I also got really lucky here with jumping over the lava river, as I almost got killed by the pursuing guards that were waiting on the other side.

7) Chapter 7
At the beginning of this segment I sold some loot and bought Reflective shield and some mana potions. Reflective shield is the only spell that I buy, because I need it to defeat Hecubah. The imps in this chapter shoot fireballs, which will kill me instantly unless my forcefield is up. The boss can be quite hard sometimes, if he gets angry. Sometimes he just casts haste on himself, runs up to you while repeatedly launching perfectly aimed fireballs at you, so I got quite lucky this time.

8) Chapter 8.
In this segment I use telekinesis to move boulders out of the way, and another swap position area skip with the help of a friendly bat. Got hit by a confuse spell from an urchin shaman, but it only slowed me down by a second.

9) Chapter 9
There were a couple of tiny mistakes here, like failing to swap with the fairy before she slowed me or bumping into a corner, but I got a perfect time on killing the 3 necromancers, which compensates for the tiny mistakes.

10) Chapter 10 part 1.
This chapter is the longest yet, and I decided to run it in 2 segments. I use invisibility to avoid fighting most of them, and in some places swap position while invisible to move quickly from 1 enemy to the next. There's a spellbook of 'wall' in one of the rooms in the teleport maze which I take for use in the next segment. I also swap fireball for turn undead, since I won't be using it anymore.

11) Chapter 10 part 2.
I use the same invisibility trick as in the previous segment to avoid fighting most of the gargoyles and all of the foes in the last room. I use the wall spell to block one of the death rays that are blocking my path, so that I'll only need to fetch 1 of the keys required to turn them off. in the spinning deathray room I have to kill the 2 liches and 2 mechanical golems before a switch is revealed, and the fastest way to do this is by using swap position to move the enemies into the rays (thanks to Risme for this insight).

12) Chapter 11.
I kill Hecubah basically with 3 spells; forcefield, burn and reflective shield. She likes to spam deathrays alot, and unless I have forcefield up she'll kill me in 1 hit. The problem is that forcefield has a slow casting time, so she usually gets the second hit in before I can reapply forcefield. This is where reflective shield comes in, since it reflects any projectile launched at you, along with deathrays. While reflective shield is up, I can reapply forcefield without dropping the shield. And of course burn to deal damage to her while she stands around.
