Just beat the Void Dragon!

[BrainSpawn]

That was sweet! Probably took me 10 tries, but I got the mofo.
Astarte kept dying on me, so I started covering her in a smokescreen as well as putting an ice wall between her and the dragon. That helped, but then I had trouble healing her, so I just stuck with a combo of ice wall and actually freezing the dragon.
I used a combo of Hail Attack scrolls and Freezing Arrows, as well as maybe knocking it down once or twice. With all the incapacitating I managed to kill the dragon before it had a chance to teleport to the other side of the room. Actually managed to get the killing blow by reflecting damage.
Found it best not to worry much about actually killing the adds, but rather CC'ing them seemed to work best. Still had to get some heals on Astarte, damn she's squishy, and that dragon really doesn't like her.
Had a couple deaths, but they got revived quickly by either Icara or Astarte, Zandalor died and was revived once too. Had some luck with charming the adds sometimes, seemed to work better on the spiders though.
It's pretty rare for me to actually finish a single player game and this is the first game of this type that I've really played. Loved it, great game. Looking forward to #2..... when it goes on sale again.
