Just to note, may be useful for people just messing around after beating the game:
I discovered you could Blizzard and Earthquake neutral NPCs and some of them will fall over/get frozen. I'm sure most of you realize this by now.
However, I found that if you used Blizzard on Duncan/First Enchanter during the Mage Origin before you get the escort Duncan quest, it bugs Duncan out and he will not actually follow you for the escort. The quest worked fine and I noticed no bad consequences from this happening but I imagine this possibility could bug later encounters so be wary.
The only issue I have with the current trainer is how you can not add more than one attribute point per strike of the Numberpad 5. Would it be possible to add an 'increase by 10' ability for attributes?
I find it just takes so long to increase attributes to a level where running with infinite mana is even worth it. If you want to have powerful abilities activated that's fine but it takes forever to increase your willpower to support the energy cost.
If it would be possible to introduce a multiple of 10 option to attribute points I'd be most thankful.
