Thanks.
Apparently I was too quick to whine, as I had a dragon skill book and I used it to purchase Dragon Spirit.
Then, I hid around my tower. Plenty of places, especially if you go out and destroy the ballistae around your tower. It is a very new thing for me, to have to cast any healing spells at all. I used to just sit in a safe place and regenerate.
This game is really difficult sometimes, and the answer isn't always within easy reach. This (and the battle with Laiken) were the only times I was really frustrated, though. A lot of times the answer can be found simply by running around and exploring. In this case, it was kinda hard to explore when I was dying in an average of 15-20 seconds.
Thank goodness my tower has more dragon armor pieces. I'll need to look into what they do more, now that I've sent upwards of 60 items to my Tower.
