I did not enjoy when i got robbed of a non lethal option when i had to pass a certain gate guarded by 3 big and very hard globins, there was a certificate i had to get signed in order to get trough a gate the problem is that when i was escaping the globin prison i made a choice of killing everyone i saw including the very person from which i needed the signature.
Arx will give you the freedom to go axe crazy and murder quest-related NPCs. You can still complete the game, even if you slaughter everyone, but it will be much harder.
Also getting killed by a guard just because you were hanging in the second floor of the king's hall is not fun, it's dumb.
The guard does warn you that the upper level is private property. You should probably listen...
Moving on i am kinda dissapointed i haven't come across any other spells besides the boring "light torches with fire", i basically poured all of my stat points in magic related skills hoping that i would be casting fireballs and crap in no time, maybe i haven't searched hard enough.
You didn't search hard enough ;) The fireball and incinerate spells are available very early on.
