The vid: https://www.youtube....eature=youtu.be
The vid is using console generated char, all items/talents are obtainable in the game. However some of the items (little savior to be exact) are not obtainable before defeating the dragon (although it might be possible to sneak into the treasury, has anyone tried that?). They are by no means necessary though, and only present since OP has taken the liberty to use superb armor/shield as well (which are definitely not obtainable without defeating the dragon). Stats/talents are not really optimized, cautious attack is a complete waste for instance since it does not stack with better wiz buffs (forgot about that). Stats are M 18 D 19 C 3 P 4 I 19 R 15 (standard glass cannon wizard). Talents are W&S, Superior deflection, Deep pockets, Bear's fortitude, Snake's reflexes and Cautious Attack. As I said CA is a waste and the only really indispensable talent is W&S, others you can skip with a bit of stat tweaking and go for stuff like veil/fast runner/caster talents.
In the vid the dragon got stuck between xaurips for a few sec, but I freed him with maelstrom. I did the fight several times to ensure I can repeat it. It is actually possible to die if you attack the dragon upfront before you get your buffs up, so it's actually better to attack the minions first and buff, but I wanted to demonstrate a facetank approach. however, with second chance item you're guaranteed to survive and get all your buffs up and running (I had it, but didn't need it), and then it's very difficult for the dragon to touch you. It is possible to raise deflection further with stuff like mirror image.
As seen in the video, I had 30+ seconds on most buffs after the dragon died (I actually wanted to use smth else than scrolls but martial prowess was still active and I didn't have a backup dps weapon) and I had enough casts to rebuff it 1-2 times more.
The fight is much easier if you use hard CC though and doable without any scrolls in this case.
Probably i could've recorded a better vid, and optimize the char better but I don't want to spend more time on it.
Edit: I'm pretty sure I can do priest and fighter as well (and priest buffs last waaay more than 10 sec, but I'm not sure I want to spend time on it)
