I decided to do some tough monster kicking and installed all the Improved Tougher 'XXXX' patches.
so there I am, a kensai/mage with only Viconia at my side (I wanted to solo but then decided to give Vicky's romance a try
first off, I found the fight was a lot tougher than I had expected, the real pain is keeping Viconia alive (or at least, not getting her permanently killed
well, after about 20 reloads and getting him down to Near Death almost every time, I got suspucious. whatever I did, he wouldn't die! once I got him to Near Death and then cast Time Stop three consecutive times and kept whacking at him all along; still, he wouldn't die. next time I cast Wish, got a double length Time Stop, then cast Time stop a further five times, without interruption; kept pounding him all the time and still he insisted on living. I added up all the damage and it turns out I did about 1000 dmg to him! that's twice the amount of his HP (500... checked with SK)! so I'm thinking 'Sc*ew you, I beat you fair and square' and decide to Ctrl-Y him... well, you guessed it - he DIDN'T die!! Ctrl-Y didn't kill him!
so I then Qtrl-Q him and sure enough, he has 1 of 500 HP left, and regardles of how much I pound him he's stuck at that 1 HP.
so now I'm stuck with an immortal dragon
