Well...it is finished. I got the Ghost point from the dragon first, then went for the hardest boss first, Josie. I found that poison weapon was no use, she's resistant to it, and plus she would insta-kill me with her spikes. I sunk my cash into the only gold charm I could afford, a very large vitality; it still didn't help, the spikes were instant death. So after a little more experimenting, I leveled deadly gift up to 2, and released 15 or so. The first five I released she killed pretty quickly, so I had to come back with 10 more. Then Moriendor, who did fall quite easily to arrow with super poison. Iona was again resistant to poison, so I scorpion'ed her too. Demonia and Cornelius were suckers for arrows with super poison.
Just a quick tip that many of you probably already know: with a poisoned melee weapon, you have to actually score a hit to poison the enemy. Not so with an arrow, it poisons them whether you score a hit or not.
For the Demon of Lies, I tried out a trick I read on these forums, as soon as he summoned his pet, I cast aura of command on it, then drank a minor shadows, sat back and watched. Kind of amazing that the Demon of Lies gets his health taken down by his pet rather quickly, while the pet suffers only minor damage. A very nice thing to watch. I killed the Demon at lvl 17, but the 201,033 xp I got from the kill pumped me up to lvl 18 right before the end movie.
